Oil-based polyurethane defoamer HY-5300

Overview:

HY-5300 is a modified polysiloxane defoamer. It is especially suitable for the bubble elimination of thick films of polyurethane coatings, and at the same time, it has a remarkable effect on the bubble suppression and elimination of spraying, roller and curtain coating methods.

Physicochemical properties:

Characteristics and uses:

1. The defoaming effect of bubbles (carbon dioxide) generated by the reaction of two-component polyurethane is extremely remarkable.

2. Inhibits and eliminates air bubbles generated during the manufacture, agitation and application of coatings.

3. Has superior inhibition and bubble breaking effect for the air bubbles generated by the baking paint system of dip coating or curtain coating operation.

4. Has good compatibility and will not cause defects such as fisheyes, pinholes, craters, etc., and is very suitable for application in various colors of topcoats and overcoats.
