The Condensation Cure Mold Silicone Rubber is a two-component silicone rubber, mainly composed of hydroxyl siloxane and crosslinker, which is cured by condensation reaction at room temperature or heating conditions. It has good flexibility, high-precision replication ability and excellent weather resistance, and is widely used in handicrafts, architectural decoration, industrial manufacturing and other fields of mold making.

Easy to handle, room temperature curing
This type of silicone rubber is usually crosslinked by mixing the base adhesive (component A) and curing agent (component B), and can be cured at room temperature without additional heating, which is suitable for a variety of complex mold production.

High precision reproduction
Due to the good fluidity and low viscosity of silicone rubber, it is able to accurately capture details and achieve high-precision reproduction. This makes it ideal for industries such as sculpture, cultural creativity, industrial prototyping, and more.

Good flexibility and tear resistance
The cured silicone rubber has high elasticity and tear resistance, and even the complex mold structure will not be easily damaged during demoulding, which helps to extend the life of the mold.

High temperature and weather resistance
Silicone rubber mold can remain stable in the temperature range of **-50 ° C to 200 ° C **, and is not easy to aging, deformation or cracking due to environmental changes, so it is suitable for hot casting, cold casting and other processes.

Suitable for a variety of materials
The silicone rubber mold is suitable for many kinds of casting materials such as gypsum, wax, resin, cement, polyurethane, epoxy resin, etc. It is widely used in the fields of sculpture, handicrafts, building components and so on.

Condensed vs. additive mold silicone rubber
In contrast to Addition Cure Silicone, the curing process releases small molecules (such as ethanol), so there may be a slight shrinkage (usually less than 0.5%) during curing. However, its price is low, the operation is simple, suitable for cost-sensitive mold manufacturing needs.

Application field
Crafts and sculpture mold: such as plaster, wax, resin crafts and so on.
Architectural decoration: such as GRC components, imitation wood, imitation stone decorative pieces.
Industrial manufacturing: Silicone molds used to make precision parts, such as plastic parts or models produced in small batches.
Food and baking: Some food grade condensed silicone rubber can be used for chocolate, sugar and other food mold manufacturing.

Precautions for use
Mixing ratio: Mix according to the manufacturer's recommended A/B component ratio, too much or too little curing agent may affect the mold performance.
Avoid moisture and pollution: condensed silicone rubber is sensitive to moisture in the air, and should be kept dry during operation to avoid contact with moisture or impurities, so as not to affect the curing effect.
Appropriate release agent: For some special materials, such as epoxy resin or polyurethane resin, it is recommended to use release agent on the surface of the silicone mold to extend the service life of the mold.

Sum up
Condensed mould silicone rubber has become an ideal mould material widely used in crafts, construction, industrial manufacturing and other industries due to its easy operation, high-precision replication ability and good durability. For mold manufacturing needs that require cost-effective, easy to operate and durable, condensed silicone rubber is undoubtedly an excellent choice.
