Description

BK-PA80 is a rheology additive composed of a polyamide and an amide wax for waterborne system. A needle-like structure is formed by itself in a coating system, as a result it prevents settling and hard caking. Unlike traditional waterborne thickening agents, BK-PA80 can provide high thixotropic property without excess viscosity increasing. BK-PA80 can improve thermos stability of the coating solution.

Typical Physical Data

Advantages

☆Excellent thixotropy, anti-sagging and anti-settling properties.

☆Easy incorporation.

☆Imparts high thixtropic property without excess viscosity increasing.

☆Excellent thermo stability

Applications 

BK-PA80 can be used in a wide range of waterborne coating systems.

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℃.

3. Additive level is 2.0-8.0 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.
