+ DRY POWDER IN-SITU ADDITION:1. For wettable resin or pigment, choose BESTGEL easier dispersing grade and add directly to accomplish in-situ incorporation:1) Solvents and resin, mix2) BESTGEL organo clay powder, mix for 10 min. 3) Polar activator, mix for 10 min. 4) Surfactant 5) Pigment 6) Dilute 2. For non-wettable resin, addition sequence is as follows:1) Solvents2) BT organoclay powder, mix for 10 min.3) Polar activator, mix for 5-10 min.4) Resin 5) Surfactant 6) Pigment 7) Dilute
+ PRE-GEL ADDITION
1) PREGEL PREPARATION
A. Charge the organic solvents to the dispersion vessel, rate of use is generally 87%. Mix
B. Add 10% BESTGEL series additive. Disperse at high speed (3000rpm) for 10min.
C. Add polar acrivator, rate of use is generally 3% Disperse at high speed (3000rpm) for 10-15 min.
2. Addiing of BESTGEL pregel:
A. For non-wettable resin (epoxy, polyester, polyacrylate, etc.), use in combination with surfactant, addtion sequence is as follows:
(1). Charge resin and solvents, mix
(2). BESTGEL pregel
(3). surfactant
(4). pigment
(5). dilute
B. For non-wettable resin and non-thixotropic pigment, addtion sequence is as follows:
(1). Charge resin and solvents, mix
(2). Surfactant (if any)
(3). pigment
(4). Disperse to desired fineness with grinding.
(5). BESTGEL pregel
(6). Disperse again to desired fineness with grinding (if required).
(7). dilute
