Adhesives and Sealants -Trimethylolpropane (TMP) is used in the production of adhesive resins such as (polyurethanes polyester polyol and polycarbonate diol).
Coatings -Trimethylolpropane (TMP) is used as a precursor for the manufacture of resins including alkyds, saturated polyesters and polyurethanes (polyester polyol and polycarbonate diol). Due to its structure, it TMP imparts high UV and chemical resistance
A. Standard Packing: In 25kg bag & 1000kg big bag.
B. TMP is hygroscopic and should be handled to prevent moisture absorption.
C. Store TMP flakes in its original packaging at low temperatures, preferably below 30ºC ( not exceed 50ºC), to avoid cake formation.
