Bentonite Clay for solvent Application:
● Marine paint, Industrial paint, heavy-duty, anticorrosion paint such as bituminous coatings, polyester paints, Alkyd paints.
● Sealant ● Inks ● Grease ● Oil Drilling Mud
Bentonite for solvent borne systems Using:
Organophilic Montmorillonite Clay GDGEL-282 disperses under high shear and requires a polar activator for best efficiency. Heat is not required to obtain good dispersion. Addition levels are typically in 0.2%~2.0%. Polar activator (95% Ethanol or 95% Methanol) is needed. Normally addition level of polar activator is recommended to be 45%~60% of GDGEL-282 in weight. If in xylene system, addition level of polar activator is about 30%-40% of GDGEL-282 in weight.
Control Additives Pre-gel is made as below procedure.
1. Charge solvent to mill
2. Slowly add GDGEL-282 (6-10% by weight of total pre-gel) to mill under agitation.
3. Mix at high speed for 5 minutes.
4. Add polar activator.
5. Mix at high speed for 5 minutes.
