• Particle Size Distribution
The following is an example of the particle size distribution for the subjected “TECHPOLYMER” series.
• Softness Adjustment
Our wide range of products with different compositions offers particles with various degrees of softness. The balance between softness and recovery rate effectively absorbs abrasion force and improves the scratch resistance of the coating. The particles also add a soft feel to the coating surface.
