Waterborne polyurethane acrylate coatings with low gloss effect
Researchers have employed a simple method to produce low gloss waterborne polyurethane acrylate coatings that work without dulling agents.
A series of low gloss waterborne polyurethane acrylate (WPUA) hybrid emulsions with different weight ratios of hard/soft acrylic monomers were synthesised.
Compared with traditional low gloss coatings that achieve low gloss effects by adding a large number of pigments, fillers or both to roughen the surfaces, the low gloss effect of these WPUA emulsions was achieved through the formation of self-roughed surfaces during film formation. Gloss levels could be as low as 3 units at 60° incident angle. In general, the WPUA emulsions that afforded films with good hardness, good adhesion strengths and excellent thermal stabilities, showed a great advantage in applications of low gloss aqueous coatings.
The study is published in: Progress in Organic Coatings, Volume 115, February 2018.
