FD503-H7 organosilicone sealant is a two-component addition type organosilicone material cured at room temperature or after hearting. This two-component elastic silicone sealant is designed for potting and protecting electronic products under harsh conditions. The formula adopts a new technology so that the product cures well at room temperature. After thoroughly and evenly mixing components A and B as per 1:1 weight ratio, the product cures into an elastic material within a certain period of time.
