Characters of Trihydroxymethylethane cas 77-85-0

Trihydroxymethylethane, also known as TME, also known as 2-hydroxymethane-2-methyl-1,3-propanediol, 1,1,1-tris (hydroxymethyl) ethane, pentaeryl glycerol, CAS number 77-85-0, EINECS number 201-063-9, molecular formula C5H12O3, molecular weight 120.15, is an odorless white crystal with a melting point of 200-203 ℃, easily soluble in water.


Main uses of trimethylolethane cas 77-85-0

Trihydroxymethylethane (TME) is a polyol used to prepare oil-free polyester resin. The compact neopentyl structure of TME molecules endows TME polyester with outstanding quality. Due to TME not having β Hydrogen, and its @ hydrogen is blocked, so TME esters have strong resistance to the destructive effects of heat, moisture, light, and oxidation. Therefore, due to the use of TME, further characteristics can be obtained, such as weather resistance, color and thermal stability, durability, light retention, baking resistance, and pollution resistance. TME alkyd resins can be manufactured with membranes, and in moderate and low oil containing alkyd resins, TME is often better than other polyols or mixtures of polyols. At the same time, TME can also endow these alkyd resins with good dry and hardness qualities.
