Condensation Cure RTV 2 Silicone Rubber with two-component, condensation-cure, tin-catalyzed, high tear strength

Decription of How to make silicone moulds without vacuum machine

Condensation Cure RTV 2 Silicone Rubber, liquid silicone rubbers are used for applications in prototyping, jewellery, special effects, model making, arts and crafts, pattern making and mould making.

Condensation Cure RTV 2 Silicone Rubber is used primarily in the mold-making industry. Silicone molds are durable, simple to construct and use, and can be used for most castable materials.

Condensation Cure RTV 2 Silicone Rubber is used in the electronic industry for potting and encapsulation. Silicones used to encapsulate electronic parts must maintain their properties over a wide range of environmental conditions.

Instruction of How to make silicone moulds without vacuum machine

Condensation Cure RTV 2 Silicone Rubber is generally named as two-part room temperature cure silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2% curing agent, they can still be operated within 30 minutes, but will be formed after 4-6 hours. With resistance to deformation, high temperature, acid and alkali, and expansion, silicon flexible molds are used for mold duplication and delicate mold making for poli crafts, resin crafts lighting and candle crafts.

Storage and Precautions of Condensation Cure Silicone Rubber RTV2

Condensation Cure RTV 2 Silicone Rubber is an environmentally-friendly liquid silicone product, is not easy to burn and can be stored and transported as non-hazardous goods. The shelf life of the product is about one year from the date of production. Inspection is required when exceeding the time limited. It can continue to be used in case of neither thickening nor deterioration.
