Products Description
1. High light transmittance, preventing the coating from turning yellow or white, suitable for optical films;
2. Significantly enhances hardness, wear resistance, scratch resistance, heat resistance and chemical resistance;
3. Reduces UV curing shrinkage rate and improves adhesion to the substrate;
4. Molecular-level nano-dispersion, unlike ordinary silica fillers, does not settle;
5. After curing, the surface has similar wear resistance characteristics to silica.

FAQ
Q: Will adding this increase the resin's viscosity?
A: Yes; since it has a high viscosity itself, adding it to the formulation will raise the overall viscosity of the system.
Q: What impact does moisture content have on the POSS curing process?
A: Water can cause the hydrolysis and destruction of the POSS cage-like silicon-oxygen structure, interfere with free radical polymerization, reduce the hardness of the coating, and easily lead to fogging and performance degradation.
Q: Storage: What are the main things to keep in mind?
A: Store in a sealed, dark, cool and dry place. Strictly prevent moisture and water ingress. Avoid high temperatures. Minimize opening the container and prevent the hydrolysis and failure of the silica cage.
Q: How is the light transmission effect of the cured product?
A: When added in the appropriate amount, it has excellent light transmission; if added in too much, it may cause an increase in haze and a whitish appearance.
