Chemi Tech Wetting Agent Solves Spreading Challenges in High-Pigment Systems

In high-pigment coatings (＞35% content), viscosity-induced uneven spreading and cratering compromise decorative and protective properties. A luxury faucet manufacturer faced fisheyes and gloss fluctuations (60° gloss ＜85) with 40% carbon black slurry. After adopting Chemi Tech's KMP-6100 wetting agent:

Dynamic Wetting Breakthrough: KMP-6100 contains fluoro-modified polyether siloxane, reducing static surface tension to ≤22.5mN/m to eliminate gas entrapment at slurry-substrate interfaces38. At 0.3% dosage, slurry viscosity dropped 32%, achieving film thickness deviation ＜0.5μm.

Process Compatibility: Added during pre-dispersion, it withstands high-pressure three-roll milling without molecular chain breakage. Post-spraying mirror effect improved (60° gloss ＞95) with zero peeling in cross-cut tests.

Extended Validation: Applied to agricultural machinery metallic paint, aluminum flake orientation increased 40%, eliminating mottling. In gradient spraying, interlayer color difference ΔE ＜0.88.

Annual rework costs decreased by ¥750,000 with 18% production efficiency gain.
