Description
BK-PA67 is a polyamide based rheology additives for waterborne system. 3-D network structure is formed by interaction with paint components in a coating system, as a result it prevents settling, hard caking, and improves pigment orientation. Unlike traditional waterborne thickening agents, BK-PA67 can provide high thixotropic property without excess viscosity increasing. BK-PA67 can be easily added into systems with a dissolver.

Advantages
☆Excellent thixotropy, anti-sagging and anti-settling properties.
☆Easy incorporation.
☆Imparts high thixtropic property without excess viscosity increasing.
☆Good water resistance.
Applications
BK-PA67 can be used in a wide range of waterborne coating systems, and is especially suitable for emulsion coatings and dispersion coatings.
Incorporation
1. Can be added at any stage. Post-addition at a final stage by a dissolver is recommended.
2. Dispersing temperature is recommended between room temperature and 40℃.
4. Additive level is 1.0-4.0 weight% as product on total formulation.
Storage
1.Keep from freezing. Freezing causes degradation of quality and performance.
2.Do not heat. Store below 40℃. Heating causes degradation of quality and performance.
