LG-622
Classification:
LG-622 contains two epoxy groups per molecule, which participate in the curing reaction to form linear and cross-linked structures. Compared with resins cured with monoepoxy glycidyl ethers, the cured resin offers improved mechanical properties, including tensile strength, flexural strength, compressive strength, and impact resistance, as well as a longer pot life.

Application:
Commonly used as a toughening reactive diluent for epoxy resins, widely applied in solvent free coatings, laminates, adhesives, and other epoxy systems. It can also serve as a cellulose finishing agent to improve the flexibility, fastness, alkali resistance, and dyeability of cellulose. Suitable for finishing cotton, linen, wool, and silk fabrics, it enhances the tensile strength of fibers.
