Feature
LG-628 is a cyclic amine modified epoxy resin curing agent, mainly used in the fields of epoxy floor coating, epoxy colored sand, epoxy grinding stone, transparent electronic packaging materials, etc. This product has the advantages of low odor, low viscosity, light color, long service life, and good resistance to yellowing. The formed cured paint film has high glossiness, hardness, strong adhesion, good toughness, and excellent characteristics such as water resistance, acid and alkali resistance, moisture resistance, birch resistance, and yellowing resistance.
