MY 2062F2 isocyanate-based silicone oil

Product Description

2062F2 is an organosilicon monomer polymer containing NCO functional groups. The NCO groups not only enhance the compatibility of organosilicon in polar systems but also facilitate reactions with active groups such as hydroxyl and amino groups. It has a high NCO content, and it has good moisture curing film-forming property and fluidity. Moreover, its molecules tend to migrate to the polymer surface before curing, highlighting the characteristics of smoothness, softness, non-stickiness and anti-fouling. The NCO group can prevent the aggregation and precipitation of silicone oil after reaction, and has good color development.
