KH-819 is a cycloaliphatic Amine modified curing agent for use with Epoxy Resins. It has very low viscosity in epoxy systems. KH-819 gives very rapid curing rate at ambient and low temperature. It can be used in formulations with good water spot resistance and resistance to amine blush and chemical resistance.

YDPN-638 has advantageous characteristics of good adhesion strength, excellent heat and chemical resistance because of its multi-functional groups in one molecule fully cross-linked. Therefore, it has excellent physical properties in addition to the basic reactivity of general Epoxy Resin.

YDF-170 is a liquid type Epoxy Resin derived from BPF and ECH. Especially, it has low viscosity without diluents or modifiers. YDF-170 has excellent mechanical, adhesion, electrical, and chemical resistance properties after being cured with appropriate curing agents . Due to its special properties, YDF-170 is generally used in coatings, moldings, adhesive, construction and civil works, and composite applications for the low VOC or non-solvent system. YDF-170 is a standard BPF type liquid resin.

YD-011 is a Bisphenol-A type unmodified solid Epoxy Resin which can be softened at medium temperature(over 40ºC). Its properties after curing are excellent for mechanical strength, adhesive strength and chemical resistance. YD-011 is recommended for industrial coating primer, top coating and construction & civil work application in solution form with Xylene or other various solvents.
