USE & PERFORMANCE
Outstanding properties: Provides matte appearance as well as superior scratch, burnish, and mar
resistance. Micro-touch additives are an ideal alternative to formaldehyde-based materials such as
polyureas. Offers tactile effects, surface touch and gloss reduction.
Recommended for products: Used in coatings for plastics, metals, paper, wood, leather and textiles.
Also used in electronics (computers, laptops, and mobile phones), automotive interiors, wall cov-
erings, parquet, vinyl flooring, inks, and furniture.
Concentrations used, wt%: 2-10% (higher amounts when greater tactile effects are desired) (on
total formula weight)
