Which cause polyurethane coatings, sealants and adhesives to thicken during storage.
(2)It is recommended especially for one-component, low- VOC polyurethane coatings. The reaction of PTSI with water introduced from pigments and solvents in the paint formulation generates carbon dioxide and soluble inert chemical products.
