solubility:
soluble in esters, ketones, aromatic hydrocarbons. in most cases, esters/aromatic hydrocarbon mixtures are used.
it is recommended to use “urethane grade” solvents for the dilution (with water content below 300 ppm).
applications:
tolonate™ hdt 90 is typically used as a crosslinker of hydroxylatedpolymers,especially polyesters and polyacrylic polyols, to prepare two-component polyurethanes coatings showing excellent outdoor durability and mechanical properties in conjunction with outstanding resistance to solvents, abrasion and chemicals.
