Apply Domain

paint Chemistry

Features and advantages: This additive strongly reduces the surface tension of the paint, so it can Improves substrate wetting and crater resistance. At the same time, it can also improve the surface slip, gloss and anti-blocking properties of the coating.

Recommended Purpose

This additive is suitable for all solvent-based, solvent-free and water-based coatings.

Suggestions Dosage

0.1-0.3 % additive dosage (as supplied) based on the total formulation.

The above recommended dosage is for reference, the optimal dosage needs to be determined through a series of experiments .

join Methods and processing instructions

This additive can be added at any production stage, including post-addition.

special Reminder

Unlike ordinary silicone fluids, this additive is "user safe". However, before use, a series of tests should be conducted to confirm the foam stability of the additive, and to evaluate its tendency to recoat and crater.
