Platinum cure molding rubber silicone rtv
Strenghts for platinum cure molding rubber silicone rtv
Platinum cure molding rubber silicone rtv is used for prototyping and the reproduction of parts. Silicone moulds can be constructed in many different forms depending on the shape of the part you are making. In this section we will outline how to create the easiest one part flat back mould.
Why platinum cure molding rubber silicone rtv
Silicone is the first choice of material when casting 3 dimentional shapes that contain undercuts as it exhibits excellent release properties, a high level of surface detail, very good chemical and high temperature resistance.
It comes in a two-component system (base + catalyst) available in a hardness range of very soft to medium. It is available for making moulds that are poured, brushed or sprayed

Warm tips for for pcb electronic potting silicone
1. Sealing pakage for storage. The mixture should be used up at once to avoid wasting.
2. Silicone belongs to non-dangerous goods, but keep away form mouth and eyes.
3. When it gets stratified after a period of storage, please mix hy-210# evenly before using,
it does not affect the performance.
Shelf life and transportation
1. Twelve(12) months when stored at 25c in original unopened packages.
2. This is a non-dangerous product, it can be transported as general chemicals.
3. Products exceed the storage life should be confirmed normal before using.
