SH-3021 Silicone Resin

Ⅰ. Features

This product is a low molecular weight and solvent-free silicone resin. It can cure at room temperature and exhibits properties such as high reactivity, high hardness, no after-tack at high temperature, low gloss loss, and low smoke emission upon heating. It can be used for heat-resistant coatings with high solid content, such as in automotive, motorcycle, and aircraft parts (e.g. exhaust systems, mufflers, and engine components.), household appliances (e.g. ovens, stoves, and grills.). It is also widely used in hardening coating materials for automotive protection.
