-------------- 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.

5. Use
Mainly used as a flexible epoxy resin flexibilizer, 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.
6. The amount of
General amount of epoxy resin 15 ~ 20% (weight ratio).
7. Packaging and storage
5kg plastic pail or 200Kg iron drum packing. Sealed to preserve.
