Hydroxy-modified polyorganosiloxane-reactive anti-scratch and wear agent 02C

Typical features

• Contains active hydroxyl groups (R-C-OH) at both ends, which can participate in cross-linking reactions with isocyanates to provide a permanent velvet smooth skin feel.
• Excellent water solubility and dispersibility, can be added directly after or after dilution with water.
• With fumed silica matting powder 1-1.5% easy to appear fluffy sense, flesh thick sense.
• It can improve the cross-linking and hardness of the paint film, and enhance the scratch resistance and solvent wiping resistance of the paint film.
• A rich and unique feel, with anti-stick and release effect.
• Does not matte, does not cause shrinkage of the coating film, but has a lightening and brightening effect on the paint film.
• Does not affect recoating.

Product Use

• Water-based coatings, inks – anti-stick, slippery, hardening, scratch-resistant;
• Leather, textile-slip, anti-adhesive;
• Used as a synthetic modifier for aqueous polyurethane resins, generally added prior to the distillation of acetone solvent for resin synthesis, thereby increasing the permanent velvet smooth feel of the resin.
• It can participate in cross-linking reaction with isocyanate, so it can be widely used in water-based two-component polyurethane leather coatings, wood coatings and hydroxyacrylic coating systems.
• It can also be used as a one-component coating after adding additives, which can also provide excellent velvet feel and scratch and abrasion resistance.
• It has been widely used in water-based wood coatings, water-based leather finishing agents, water-based paper varnish, water-based tactile coatings, water-based UV coatings, inks, etc.
• Also suitable for solvent-based coatings and UV matte coatings, inks, etc.

Quality Indicators

How to use

• Water-based wood varnish, paper varnish : 0.5%.
• Leather coatings: 1-3%.
• Other industrial coating inks: 0.5 – 0.8%.
• It can be added directly, it is recommended to pre-dissolve and dilute with water 1:1 or soak the product with water in the system for 10-12 hours to dissolve before doing the addition.
• It can also be added directly to systems with good compatibility.

Warm Tips

• As silicone products migrate slowly in some water-based one-component systems, the feel comes out slower, so it is recommended to place at room temperature
• Observe the effect after 5-7 days, or the effect will be brighter and better after the sample is baked for 3-4 hours at medium to low temperature 40-60°.
• If you need the product to get a strong velvet feeling, you need to use with about 1-1.5% matting powder, the effect is better.

Storage conditions

• Store airtight, at room temperature and avoid exposure to sunlight.
• Avoid contact with strong acids, strong bases and strong oxidizing substances.
• Effective storage period is 1 year, after the storage period, after testing qualified can still be used normally.
