"KER"
epoxy resins produced and marketed by
Kumho P&B Chemicals, Inc. They are
commercially established as major raw
materials in the field of coatings,
adhesive, civil engineering, structural,
electronic and composite applications.
The
basis of the product is KER 828 liquid
epoxy resin, Bisphenol A glycidyl
ether. The product line includes liquid
resins, solid resins, solutions, blends
and other special resins based on
a variety of formulas. As these products
are used with various curing agents,
diluents and modifiers, an almost
unlimited range and variety of properties
may be obtained. |

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