Sales: Polypropylene glycol diglycidyl ether (epoxy diluent D-1217 )

-------------- activity flexibilizer flexible epoxy resin, toughening effect better than the D-410

1. Description
D-1217 polypropylene glycol diglycidyl ether, polypropylene glycol by reaction with epichlorohydrin from dehydration, pale yellow liquid, because of its unique molecular structure of long-chain type can therefore replace the commonly used D-410 Central Oxygen Flexible flexibilizer was. is widely used in solvent-free coatings, laminates, adhesives such as epoxy system. As a cellulose fiber finishing agent can increase flexibility, fastness, alkali resistance, dyeability, etc., can be used for cotton, hemp, wool silk and other fabric finishing. Can improve the tensile strength fibers.

     2.Nature: many contain propylene glycol ether of the structure of epoxy resin. Epoxy equivalent 150 ~ 360g/eq. Viscosity (25 ℃, Pa s) 0.02 ~ 0.10. Relative density 1.07. Adaptation by oligomeric polypropylene glycol with epichlorohydrin reaction. Often associated with bisphenol A type epoxy resin used in conjunction. Mainly used for the adhesive and its modifier, resin modifier, paper processing aids, fabric treatment agent. Epoxy resin used as a common reactive plasticizer; and degree of polymerization for the following 3 bisphenol A epoxy resin is used as a reactive diluent.
