R77F

R77F is a processing aid (plastic internal-additive-type breathable water- and oil-repellent agent), not a masterbatch: a white powder, three-component, added directly into chemical fiber and plastic raw material systems. The manual page title reads verbatim "Breathable water- and oil-repellent agent R77F", while the table-of-contents line and the official full name read verbatim "Plastic internal-additive-type breathable water- and oil-repellent agent R77F"; the website list title and detail page title read "Hydrophobic agent (containing fluoride ions)" and "Plastic internal-additive-type hydrophobic agent (containing fluoride ions)". The naming at each level coexists; this page records them layer by layer without altering one another. (Data source: product handbook / official product data)

Main components verbatim: "Silicon dioxide 27.5% hydrogenated silicone 56% magnesium oxide 16.5%" — the three items written adjacent to one another, totaling 100%. As for the role of magnesium oxide (16.5%) in this product, the materials give no functional description (the entire source has only one mention, the ingredient table); this page states only the compositional facts and makes no mechanistic inference. (Data source: product handbook / official product data)

Overview verbatim (main mechanism line): "The process of adding the breathable water- and oil-repellent agent R77F internally into chemical fiber products to lower the surface tension of the fibers, so that water droplets cannot wet the surface, is called water and oil repellency, also known as breathable waterproof and oil-proof. It is suitable for materials such as raincoats, shell jackets, travel bags and protective clothing. The water- and oil-repellent effect of the fabric is also related to the fabric's structural organization. Fabric to which the R77F water- and oil-repellent agent has been added can still maintain its breathability. Because it is an internal-additive-type water- and oil-repellent agent, it has excellent resistance to washing, dry cleaning and rubbing, as well as breathability and durability, etc. It can also be used for anti-fouling plastic films and various anti-fouling plastic components, etc." (Data source: product handbook / official product data)

Separate note on the fluorine position (specific to this product): the official data layer registers it as "containing fluoride ions (contains no perfluorinated or organofluorine compounds, can pass perfluorinated checks)"; the compliance narrative follows the perfluorinated-compliance direction — this product does not belong to a halogen-free system, and the page writes no compliance statements in the halogen direction. This grade does not involve flame retardancy, and there is no flame-retardant rating or flame-retardant mechanism. (Data source: official product data)

• Definition of water and oil repellency (source text) — "the process of lowering the surface tension of the fibers, so that water droplets cannot wet the surface, is called water and oil repellency, also known as breathable waterproof and oil-proof".
• Breathability retention — "fabric to which the R77F water- and oil-repellent agent has been added can still maintain its breathability"; the page wording is "does not affect the fabric's original breathability performance".
• Durability chain — "excellent resistance to washing, dry cleaning and rubbing, as well as breathability and durability, etc."; the page wording is internal-additive-type modification, with the active ingredients deeply fused with the substrate.
• Perfluorinated compliance (official wording, verbatim) — "containing fluoride ions (contains no perfluorinated or organofluorine compounds, can pass perfluorinated checks)"; the official data/list layer uses "perfluorinated checks" and the page layer uses "perfluorinated testing", recorded layer by layer as written.
• Application examples — materials such as raincoats, shell jackets, travel bags and protective clothing; also "anti-fouling plastic films, various anti-fouling plastic components, etc.".
• Conditional statement on effect — "the water- and oil-repellent effect of the fabric is also related to the fabric's structural organization": the effect results from the combined action of the additive and the structural organization.

Composition facts: white powder, three-component formulation — silicon dioxide 27.5%, hydrogenated silicone 56%, magnesium oxide 16.5% (totaling 100%). The materials give no role annotations or compatibility explanations for each component; this page does not presume to assign roles. (Data source: product handbook / official product data)

The action route is internal addition: the additive enters the interior of the chemical fiber system, lowering the fiber surface tension so that water droplets cannot wet the surface — this is the source's definition of "water and oil repellency = breathable waterproof and oil-proof". Because it comes from internal modification of the system rather than a surface coating, the water-repellency durability chain (resistance to washing, dry cleaning and rubbing, breathability, durability) holds together with "still maintaining breathability". (Data source: product handbook / official product data)

The three feature cards on the page layer (qualitative statements, not measured data): (1) eco-friendly perfluorinated compliance — "although it contains fluoride ion components, it is completely free of perfluorinated and organofluorine compounds (such as PFOA / PFOS and other organofluorine pollution sources), and can smoothly pass all stringent perfluorinated testing indicators"; (2) biomimetic lotus-leaf effect — water beads form round droplets on the surface and quickly roll off, providing anti-fouling self-cleaning; (3) internal addition for high durability — resistance to washing, dry cleaning and rubbing, without affecting the fabric's original breathability performance. Quantitative criteria such as contact angle values, water-repellency ratings, durability cycle counts and retention rates are not given in the materials, and this page does not cite them as measured data. (Data source: official product data)

1. Internal addition — entering the chemical fiber systemAdded in the internal-additive manner into chemical fiber products (fabrics) or plastic systems; the specific process steps, mixing equipment and parameters are not given in the materials, and this page does not presume to draft them.
2. Lowering surface tension — water droplets cannot wetLowers the surface tension of the fibers, so that water droplets cannot wet the surface — this is the source's definition of water and oil repellency (breathable waterproof and oil-proof).
3. Breathability retention — fabric structure stays unblockedThe fabric after addition can still maintain its breathability; the page wording is "water vapor passes through freely · breathability retained".
4. Durability performance — resistance to washing / dry cleaning / rubbingThe durability chain brought by the internal-additive route: resistance to washing, dry cleaning and rubbing, breathability, durability; the page wording is deep fusion of the active ingredients with the substrate.

The physicochemical specifications recorded in the product handbook and official product data are as follows (the in-page wording and ordering of the specifications follow each page's original form, transcribed as-is by layer and not mutually altered). The values in the table are those recorded in the source materials; before bulk use, it is recommended to carry out small-scale trials with your own system.

Reading notes: (1) The specific surface area is written on the handbook page as "230+25M2/g" ("M2" is the in-page original notation); (2) The loss on ignition is written on the handbook page as "<72Wt%"; (3) The specification pages' wording and ordering follow each page's original form and are not mutually overwritten or unified with other model pages; (4) The role of magnesium oxide in this product is not explained in the source materials. (Data source: product handbook / official product data)

The dosage uses a single basis: the denominator is the plastic final product (as stated in the source), range 0.8%—1%; the handbook, the official dosage field, and the page presentation are consistent in all three places. The source gives no breakdown by substrate or scenario.

Denominator note: this model has only one denominator basis — the plastic final product; the source gives no substrate breakdown. Thickness-direction clause: none for this model (a full-source search for "thickness / thinner" returns no record relating to this model); this page uses no directional wording and does not apply the directional clauses of other models.

To be verified: (1) Dosage breakdown details and upper-limit verification — the source gives only the overall range "0.8%—1% of the plastic final product", and none is drafted here. (2) Processing details (process steps, mixing equipment requirements, feeding order) are not given in the source. (3) The quantitative criteria for the "lotus effect / hydrophobic and oleophobic" behavior and durability (contact angle, water-repellency grade, wash / dry-clean / abrasion cycles and retention rate) are not given in the source. (4) All of the above are values recorded in the source materials; for actual production, please conduct small-scale trials in combination with the fabric structure and process.

The application examples given in the source overview and the official application field (breathable functional film, protective clothing fabric, breathable packaging) are itemized as follows; this model's page has no separate [Application scope] subsection, and this page does not fill one in.

Boundary note

This product has the opposite direction from R77 (R77 is a fluorine-free system, while this product follows the fluorine-ion direction) — the two form a paired set of pages, are not interchangeable, and their values are not cross-applied; no code-by-code correspondence with the masterbatch-side models is recorded for this product, and dosages are not cross-calculated.

Field issues & application examples (as recorded in the source material)

R77F and R77 are paired page for page, opposite in direction; they differ in fluorine direction, number of components, specification values, and dosage. The comparison is as follows (for demarcation only, not an equivalence comparison):

Reading notes: (1) The two grades are identical only in two items—appearance and moisture content (white powder / moisture content <3Wt.%); the rest are differences as written on their respective pages; (2) The dosage values differ (0.8%—1% vs 0.5%—1%) and must not be cross-used; (3) The compliance positions on the pages are independent of each other (this grade's side is perfluorinated compliance; R77's side is fluorine-free and environmentally friendly) and are not interchangeable; (4) This table serves for demarcation only and is not an equivalence comparison of performance. (Data source: product handbook / official product data)
