Commonly used in the production of liquid silicone molding belongs to a new type of material, mainly composed of poly vinyl sealing end (or side base) polydimethylsiloxane, crosslinking agent containing hydrogen silicone oil, platinum catalyst, according to the requirements of product application, add the corresponding filler, inhibitor, color paste, fragrance and other additives.Filler is also known as filler, filler is usually quartz powder, gas phase method or precipitation method of silica black, inhibitors for alkynyl alcohol inhibitors.Its shrinkage rate is small, curing ability is strong, mechanical and electrical properties is excellent, easy to shape, is the modern generation of life of the excellent functional materials, widely used in electronic and electrical, automotive, medical and other fields.

Add molding liquid silica gel is how to cure?What is its principle, and the new best together to understand.

Add molding liquid silica gel curing principle is to add catalyst (platinum catalyst) in silica gel, catalytic reaction to make its curing.

Additive liquid silicone rubber usually uses platinum catalyst, and its reaction conditions are mild. It is often used in the synthesis of downstream products of silicone and the preparation of room temperature curing coatings and adhesives.However, due to the high activity of platinum catalyst, the operation time of cross-linking catalysis is short.The reaction control of platinum-catalyzed silohydrogen addition reaction needs to select appropriate catalysts according to the solubility and catalytic speed in the basic polymer.

To sum up, after we buy liquid silica gel, it is necessary to add the curing agent to make it cured. Grand plan reminds you to make silica gel mold when buying liquid silica gel, don't forget to let the seller give your silica gel with curing agent.Do not know how to ratio and fixed partners can contact and consult us hongtu silica gel, we will provide you with high quality silica gel and after-sales service.
