PRODUCT NAME: EPOXY RESIN WB-121
PACKING: ISO TANK / IBC / DRUM
DESCRIPTION: WB-121 IS A HGH PURITY LIQUID EPOXY RESIN PRODUCED FROM BISPHENOL A AND EPICHLOROHYDRIN. BECAUSE OF ITS HIGH PURITY AND LOW POLYMER FRACTIONS CONTENT, WB-121 EPOXY RESIN ASSURES UNIFORM PERFORMANCE AND EXCEPTIONALLY LOW VISCOSITY, LOW CHLORIDE CONTENT AND LIGHT COLOR. IT PROVIDES IMPROVED ELEVATED TEMPERATURE PROPERTIES UNDER SOME CURE CONDITIONS. CYCLOALIPHATIC POLYAMINES, POLYAMIDES, AMIDOAMINES, AND A WIDE VARIETY OF CURING AGENTS CAN BE AVAILABLE TO CURE WB-121. WB-121 EPOXY RESIN MIGHT CRYSTALLIZE. THIS REVERSIBLE, PHYSICAL PHENOMENA CAN BE GREATLY AVOIDED BY STORING THE RESIN AT TEMPERATURES NOT BELOW 25ºC.
APPLICATIONS: WB-121 IS USED MAINLY IN FILAMENT WINDING, ELECTRICAL LAMINATES AND ENCAPSULATION, MARINE AND PROTECTIVE COATINS, ADHESIVES, COMPOSITES APPLICATIONS.
