A paint company in Shanghai proposed that pinholes, fisheyes and shrinkage cavities occur in the coating film

Purpose: How to avoid pinholes, fisheyes and shrinkage cavities in the coating film

Recommended: WPL-ink defoamer

Usage: Add 1-5ppm ink defoamer to oil-based paint to improve paint leveling, hydrophobicity, mold release and defoaming, and avoid pinholes, fisheyes and shrinkage cavities in the coating film.

Results: The surface tension of the ink defoamer is low, and it is easy to spread on the solid surface whose critical surface tension is greater than it, and can also spread on the surface of the liquid whose surface tension is greater than and does not dissolve it, so that it presents leveling and smoothness on these surfaces. Hydrophobic, mold release and defoaming properties, avoiding pinholes, fisheyes and shrinkage cavities in the coating film.
