Recommended dosage
0.1-0.7 % Auxiliary dosage (as purchased) is based on the total formulation.
The above recommended dosage is for reference, and the optimum dosage needs to be determined through a series of tests.
Joining method and processing guidance
For optimum defoaming, defoamer should be added to the millbase. If added later, the shear force must be high enough to ensure good dispersion of the defoamer to prevent cratering.
Room temperature curing plastic system
Product features and advantages: defoaming agent, inhibits the generation of foam and air bubbles in the production and construction of room temperature curing plastics.
Recommended use
Recommended for polyurethane-based casting materials (including electronic potting).
Recommended dosage
0.1-1 % Auxiliary dosage (as purchased) is based on the total formulation.
The above recommended dosage is for reference, and the optimum dosage needs to be determined through a series of tests.
Joining method and processing guidance
It can be added to the resin before other components are added, and it can also be added to the whole system.
