Description

BK-PA63 is a specially modified aqueous polyamide wax rheological additive that  forms a 3-D network structure in aqueous coatings, providing anti-settling and anti- caking effects, and enhancing pigment alignment properties.It is very easy to disperse.Unlike traditional waterborne thickening agents, BK-PA63 provides high thixotropic properties without increasing extra viscosity to the system.

 Typical Physical Data

Advantages

☆Excellent anti-settling properties to prevent hard settling.

☆The positioning of metallic and pearlescent pigments increases the glossiness of the paint film.

☆It is easy to disperse and can be dispersed by a high-speed disperser without grinding.

Applications

BK-PA63 can be used in a wide range of industrial and civil waterborne coating systems.Especially,suitable for emulsion coatings. 

Incorporation

1. Can be added at any stage. Post-addition at a final stage by a dissolver is recommended.

2. High speed disperser is recommended. High shear equipment such as sand mill to be avoided.

3. Dispersing temperature is recommended to be under 40℃.

4. Additive level is 1.0-4.0% by weight of total formulation.

Storage

Store in cool and dry places between 10-40℃.Shelf Life: 2years.
