KER Liquid Epoxy ResinsLiquid "KER" Epoxy resins are used in several major industries, notably the paint industry(high-solid and
solvent-free coatings), the Electrical industry(casting, potting, encapsulation), the building industry(floorings,
mortars, grouts, adhesives) and in many other application e.g., structural laminates, high performance
adhesives , etc.. The KER range contains resins with different reactivities , viscositie s and handling
characteristics, which provide a wide choice to the user.

KER Solid Epoxy ResinsSolid KER epoxy resins are mainly used in the manufacture of solvent-borne paints, air-drying epoxy esters,
can coatings, PCM(coil) coatings, powder coatings, printing wiring board and moulding powders. The KER
grade range contains resins of different molecular weight. All solid KER epoxy resin grades, manufactured by
Kumho P&B Chemicals, Inc., are characterized by a low and consistent hydrolizable(or saponifiable) chlorine

Epoxy curing agents are used to cure epoxy resins by reacting with the epoxide groups or by promoting
self-polymerization of the epoxy by catalytic action. Application characteristics and final physical properties
can be tailored by the choice of curing agent. Kumho P&B Chemicals, Inc. offers a wide variety of epoxycuring agents/hardeners in the following classifications.
