Technical Details & Test Data

Performance Evaluation

Scrub resistance

Scrub resistance was evaluated according to ASTM D 2486 using a PVC 60 formulation with a VAE latex and different Alcosperse grades. The effect of additional non-ionic wetting agent was also evaluated.

Color acceptance performance

Color acceptance, in a PVC 60 formulation, using the Alcosperse grades was evaluated for three different types of binders in combination with two of our Bermocoll products. The amount of colorant was 3% based on total paint weight.
