     Application:

    1.Alkyd resins

    2.Saturated polyesters 

    3.Synthetic lubricants

    4.Monomers/oligomers for radiation curing 

    5.Pigment coating

    6.Polyurethanes for coatings and foams 

    Di-TMP is increasingly used in environment-friendly applications like radiation-curing acrylate esters,resins for surface coatings with the highest demands on outdoor durability,synthetic lubricants,and as micronzied in PVC stabilizers.

    Packing25kg,500kg or 1000kg bags, or upon customer's request.

    Storage: Prevent moisture absorption. Store at low temperatures, preferably below 30℃, to avoid cake formation. Do not exceed 50℃. Stacking pallets during storage could increase the risk of caking
