Tin-cured silicone (condensation-cure silicone) is a room-temperature vulcanizing (RTV) silicone that uses tin-based catalysts (e.g., dibutyltin dilaurate) to cure. It is widely used for mold making, casting, and sealing due to its cost-effectiveness and ease of use.

Platinum-cured silicone (addition-cure silicone) is a two-part, platinum-catalyzed liquid silicone rubber that cures into a non-toxic, odorless, and highly transparent elastomer. It is ideal for food, baby care, electronics, and precision molding applications where safety and accuracy are critical.
