Product Description

High Efficiency Modified Bentonite Clay Organoclay for ink

GDGEL-281 RHEOLOGICAL ADDITIVE

High Efficiency Modified Bentonite Clay Description:

GDGEL-281 is an organo clay (modified bentonite), designed especially for use  in solvent based system. It can be used widely in solvents from low polarity to medium-high polarity.

Bentonite Clay Using:

GDGEL-281 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 40%~50% of GDGEL-281 in weight. If in xylene system, addition level of polar activator is about 30%-40% of GDGEL-281 in weight.

Pre-gel is made as below procedure.

1.    Charge solvent to mill

2.    Slowly add GDGEL-281(6-10% by weight of total pregel) to mill under agitation.

3.    Mix at high speed for 5 minutes.

4.    Add polar activator.

5.    Mix at high speed for 5 minutes.
