Chemical reaction · professional additive
DD550 is a professional additive developed for the permanent anti-static needs of leather, made by precisely proportioned chemical synthesis; it offers excellent conductivity and good dispersion.
11 Ω · fast and lasting
Low resistivity: static dissipates quickly and durably; it is well compatible with water and common solvents, making immersion baths easy to prepare.
Leather colourway unaffected
Colour coverage is extremely low and it does not affect the leather’s inherent colour, so it suits any leather colour — hover the swatches to verify "treated but unchanged":
Specification
Alkaline system (pH 10.26–11.0) — finished goods must avoid strong acids to prevent acid hydrolysis of the conductive factor.
Alkaline system
This product is an alkaline system (pH 10.26–11.0); use alkali-resistant mixing and storage vessels.
Pore immersion bench · 50–60 ℃ process
Toggle the temperature: at room temperature the pores are closed and ions float on the surface; at 50–60 ℃ the pores open fully and conductive ions penetrate deeply.
Stir first · then add to water
Before use stir thoroughly, then add to water in proportion; the dosage is generally 0.2% – 0.5% of the water.
Undiluted · do not touch
Before immersion treatment with this conductive agent, do not touch it with bare hands while undiluted.
Use together with R810
Best used together with our R810 additive, which markedly improves the adhesion of the conductive factor on leather.
Pigments or dyes may be added
Depending on the colour required, pigments or dyes may be added to the bath; it is compatible with leather colour-matching systems.

Key points at a glance
01Product positioning
Name and positioning. The data page is titled 'Permanent antistatic agent DD550 for conductive leather'; the mechanism field is 'antistatic via conductive channels'; the main component is 'ionic antistatic agent'. (Data source: product handbook / official product data)
Overview (quoted verbatim): 'DD550 permanent antistatic agent was developed by our company for permanent antistatic properties in leather. It is formed through a precisely proportioned chemical reaction. It has excellent conductivity and good dispersion performance. It has a good effect on the treatment for manufacturing antistatic high-end leather.' (Data source: product handbook)
Advantages (quoted verbatim): 'Superior conductive performance and relatively low resistivity, good compatibility with water and solvents, very low color hiding rate, suitable for use in any leather color formulation.' (Data source: product handbook)
Data status note (quoted verbatim): 'Note: This product is not a regular product of our company, has no third-party test report, and is only a trial product used on leather for the first time. Customers are advised to have the treated leather undergo third-party testing to see whether it can meet the relevant requirements.' — Quoted verbatim, without interpretation. (Data source: product handbook)
- Performance indicators: appearance 'off-white paint-like liquid'; PH value 10.26-11; density 2.6; resistance 11 ohms; solids content 60% (quoted verbatim).
- Usage points: stir evenly first, then add to water in proportion; condition 'it is best to maintain a temperature of 50-60℃', so that the leather pores are fully opened and conductive ions can easily penetrate.
- Combination usage: the documentation records, 'In the liquid, it is best to use it together with our company's R810; R810 can improve the adhesion of conductive factors.'
- This grade is a historically listed grade (Discontinued); the documentation is retained; this page is compiled as-is from historical documentation.
02Formulation system & mechanism of action
Action path (as stated in the documentation): during the immersion process, conductive ions penetrate the leather pores under the water temperature conditions, forming a permanent antistatic conductive channel; the documentation describes this process as 'immersion treatment using a super conductive agent,' and emphasizes that before treatment, when it has not been mixed with water, do not touch it directly with hands. (Data source: product handbook)
Compatibility and appearance: good compatibility with water and solvents, very low color hiding rate, suitable for use in any leather color formulation; conductivity is described as 'excellent', resistance specification 11 ohms (quoted verbatim). (Data source: product handbook)
Adhesion enhancement: the documentation recommends using it together with R810 to improve the adhesion of conductive factors. (Data source: product handbook)
- Liquid preparation — add to water in proportionBefore use, stir evenly first, then add to water in proportion; the addition ratio is generally 0.2% to 0.5% based on water.
- Penetration — soaking under 50-60℃ conditionsFor use conditions, it is best to maintain a temperature of 50-60℃, so that the leather pores open fully and conductive ions can easily penetrate.
- Stabilization — adhesion and protectionUse together with R810 to improve the adhesion of conductive factors; the product after soaking should avoid contact with strong acids to prevent acidolysis of the conductive factors.

04Recommended dosage window
The source gives one sentence on this product's addition ratio and includes the complete soaking process:
| Scenario | Dosage | Conditions & notes |
|---|---|---|
| Addition ratio | 0.2% to 0.5% based on water | Original source text: "The addition ratio is generally 0.2% to 0.5% based on water."; denominator is water |
The denominator is explicitly stated (ratio based on water). The source also provides a soaking process: soak in solution at 50-60℃ for 90 minutes → remove and immediately place in water at ambient temperature and soak for 10-30 minutes → after air-drying to 50% dryness, immerse in clean water to soak (quoted verbatim from the source). Determine the value through small-scale trials according to leather type and process.
This entry is the only dosage record for this grade in the source, and the denominator is explicitly stated (based on water); this page does not devise other bases or convert across grades. (Data source: product handbook)

06How it differs from related grades
DD550 is in the leather antistatic direction. Models that also involve the 'conductive / antistatic' theme differ in direction; select according to the target. The comparison is as follows:
| Model | Data positioning (key points) | Primary target / direction | Dosage (documented) |
|---|---|---|---|
| DD550 | Permanent antistatic agent for conductive leather; ionic antistatic agent | Permanent antistatic treatment of leather (immersion process) | 0.2% to 0.5% based on water |
| D3-A | Waterborne super-conductive carbon black hyperdispersant (waterborne dispersion and adsorption) | Super-conductive carbon black; immersion-type superconducting electronic products | 1-2% (by total formula weight); 5-8% (by total liquid amount) |
| S007 | Zinc-based nano antimony-doped tin dioxide (transparent conductive material) | Transparent conductivity and antistatic, UV and IR blocking for glass / plastics / resins (coating) | No dosage column is provided in the data (no numerical value is given on this page) |
Reading note: The three models all involve the conductive / antistatic theme, but their categories and targets differ (leather antistatic / waterborne dispersion / transparent conductive coating); the numerical bases differ and cannot be applied interchangeably. (Data source: product handbook)
