Product features and advantages

The defoaming agent is especially recommended for emulsion systems with pigment volume concentration in the range of 20-40. High shear force will not affect the defoaming effect of the product.

Recommended use

It is especially recommended for high gloss emulsion system, gloss and semi-gloss latex paint. Also suitable for high pigment volume concentration of latex paint/exterior paint and emulsion stucco.

Suggested usage

0.1-0.5 % additive amount (purchase form) based on the total formula. Up to 0.8 % under certain circumstances.

The above recommended dosage is for reference only, and the appropriate dosage needs to be determined through a series of tests.

Adding method and processing instruction

Under normal circumstances, 2/3 of the amount of the defoaming agent can be added to the abrasive and 1/3 of the amount can be added to the mixing or finished paint. In order to avoid defects, it must be added with sufficient shear force.
