Organic Silicone Resin LR-021

This material is a resin with a highly cross-linked structure. Once cured, it exhibits high hardness and, when combined with inorganic fillers, demonstrates excellent temperature resistance. After undergoing high-temperature sintering, it forms Si-O or Si-C bonds, resulting in a high residue content. Even under extreme heat conditions, it maintains strong adhesion.
