HOS 182 is a high molecular weight polydimethylsiloxane emulsion, excellent smoothness and anti-adhesion, excellent surface smoothness and scratch resistance, unstable foam, easy to add, broad compatibility, the addition amount is 0.1-0.5%. Used in printing inks, wood coatings and leather topcoats.
Due to the incompatibility of the siloxane segments in the modified silicone, they will migrate to the gas-liquid interface and will be quickly and directionally arranged on the surface of the paint film. The coating surface has the effect of smooth, anti-scratch and anti-adhesion due to the enrichment of sufficient silicon oxygen chain segments.
Development Background:
It is a polymer feel agent that can address the issues of abrasion resistance and scratch resistance in paint film without compromising compatibility.
When formulating coatings, it is important to consider both decorative and protective functions. Traditional polymer feel agents often have poor water solubility, leading to incompatibility issues in water-based formulations and affecting the permeability of the paint film. However, this product undergoes a special emulsification process, greatly improving its water solubility. It exhibits good fluidity, making it easy to add and disperse. It is available in 80% solid content aqueous solution.
This product achieves a balance between smoothness, wear resistance, adhesion resistance and the ease of addition and compatibility of ultra-high molecular weight siloxane.
