Adding dry powder

1. For wettable resin or pigment, choose BT-838S, BT-840 or BT-860 and add directly to accomplish in-situ incorporation

1) Solvents and vehicle, mix

2) BT organobentonite powder (mix for 10 min)

3) Polar activator (10 min)

4) Surfactant

5) Pigment (disperse)

6) Dilute

2. For non-wettable resin, addition sequence is as follows:

1) Solvent and mixed solvent

2) BT organobentonite powder (mix for 10 min)

3) Polar activator (mix for 5-10 min)

4) Resin (mix)

5) Surfactant

6) Pigment (disperse)

7) Dilute

This method is suitable when there is large amount of solvent for use when while molding.
