In polyurethane, amino resin, and other coating and adhesive systems, how to endow materials with the unique properties of silicone without altering the main formulation structure has always been a key focus of industry technological innovation. IOTA 2120 Carbinol Silicone Oil, with its high reactivity of terminal hydroxymethyl functional groups, can precisely introduce silicone properties such as weather resistance, hand feel, stain resistance, and low-temperature resistance into resin systems through chemical crosslinking, achieving comprehensive improvement of resin performance.

Product Core Characteristics

IOTA 2120 is a polydimethylsiloxane compound with terminal hydroxymethyl functional groups, with a molecular weight of approximately 2000 and active ingredient content exceeding 99%. Its terminal hydroxymethyl structure can undergo crosslinking reactions with polyurethane, amino resin, and other systems, achieving chemical bonding of silicone segments to the resin backbone rather than simple physical blending.
