Application
2-Methyl-1,3-propanediol is used in polyesters for solvent- and waterborne coatings, imparting them lower viscosity than neopentyl glycol, easy processability, good flexibility, weatherability, and toughness. 2-Methyl-1,3-propanediol is used in paints with low content of volatile organic compounds (VOC) as two-component polyurethane coating and coil coating. It is also used in glass-fiber-reinforced unsaturated polyesters and gel coats. MPO is used for chemical modification of polyethylene terephthalate (PET) used in production of fibers and films. Low content of MPD in PET fibers improves the dye uptake and in films it improves clarity, toughness, elongation, and shrinkage. Plasticizers, elastomers, adhesives, cosmetics, and personal care products are other uses of MPO.
Storge & Handling
MPO should be stored in a cool, dry place away from light and heat sources to prevent degradation or unwanted reactions.
