FIELD: chemistry.
SUBSTANCE: present invention relates to formaldehyde-free coating compositions. The coatings are used to endow fibrous panels and acoustic panels, such as ceiling tiles, with sag resistance. The composition includes a polyacid copolymer having at least two carboxyl groups, anhydride groups or salts thereof, a compound having a hydroxyl group, a phosphorus-containing catalyst and calcium aluminosilicate powder.
EFFECT: sag resistance, rigidity and strength of the formaldehyde-free coating.
