Recommended dosage
0.1-0.7 % Auxiliary dosage(purchase form)Based on total formulation.
The above recommended dosage is for reference,The optimal amount of addition needs to be determined through a series of experiments.
Adding method and processing guidance
For best defoaming effect, Defoamers should be added to the millbase. If added later,shear must be high enough to ensure defoamerGood dispersion,to prevent cratering.
room temperature curing plastic system
Product Features and Benefits: defoaming agent,inhibits room temperature curing plastics from producing foam and air bubbles during production and construction.
Recommended use
Recommended for polyurethane casting materials(includes electronic potting).
Recommended dosage
0.1-1 % Auxiliary dosage(purchase form)Based on total formulation.
The above recommended dosage is for reference,The optimal amount of addition needs to be determined through a series of experiments.
Joining method and processing guidance
Before other components are added to the resin, can also be added to the entire system.
