Those who often use liquid silicone should know that mold silicone is divided into two types: addition type condensation type. The materials uses are also different. The following Hongtu liquid silicone manufacturers tell you addition type condensation type the composition use. Uses differences between silica gel.

Composition use of liquid silica gel in addition mould:

Addition molding liquid silicone mold silicone is a two-component addition molding environmentally friendly silicone. It consists of two parts: component A is silica gel, component B is catalyst, the two components are mixed used in a ratio of 1:1; environmentally friendly, non-toxic, odorless, transparent liquid silicone material, temperature-resistant -65 degrees- 250 degrees, limited by the thickness of the product, it can be cured at room temperature for 1-3 hours, it can be cured at 100 degrees for a few minutes. Due to the environmentally friendly, non-toxic odorless silicone material of the addition mold, it can be used in human wax models, simulated robots, simulated human wax figures, adult products, food food material molds, cake molds, candy molds, simulated dishes, dental mold making, yacht gel coats , Yacht gel coat other silicone products rubber mold making, all uses of the condensation mold silicone can be applied to add molding.

Liquid silicone condensation mold silicone A, B component ratio is generally 100: 2 ~ 2.5, using organic tin curing agent, will produce small molecules, a little smell, the default color is white translucent, other colors Can be modulated with pigments; room temperature vulcanization molding, easy to demould. Condensation mold silica gel is mainly used for cultural relic reproduction, resin handicraft jewelry mold making, plaster product complex mold making, cultural stone other building materials product mold making, toy gift model complex mold, imitation mahogany furniture, shoe mold making, Buddha carving crafts, etc. Product model duplication mold making in various industries.
