Brief Introduction of Resin Casting Mold Making Silicones RTV-2 Rubber:
Liquid silicone rubber is a two component material, and it consist of Part A base silicone and Part B curing agent. When the two parts mix together and pour or brush on a object, the silicone base and curing agent can cure to be a silicone mold at room temperature; And 24 hours later, the silicone mold can be released from the object.
Characteristics of Resin Casting Mold Making Silicones RTV-2 Rubber:
1. Good flow ability and long working time
2. Medium hardness, Low viscosity - easy for pouring
3. High tear and tensile strength
4. Easy de-mould from complex replica parts
5. Acid and alkali-resistance
6. Low linear shrinkage
Extensive Applications of Resin Casting Mold Making Silicones RTV-2 Rubber:
RTV-2 silicone rubber can be used in the duplication of cement molds, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds. etc.
Procedures of Resin Casting by Mold Making Silicones RTV-2 Rubber
1. Make sure the surface of the original is clean and free of loose material.
2. Weight 100 Part A base and 2 parts of CA30 Curing Agent in a clean container.
3. Stir Part A base silicone before use thoroughly, as filler separation may occur upon prolonged storage.
4. Mix Part A and Part B evenly until the CA30 completely dispersed in the base.
5. Pour the mixed Part A base silicone and CA-30 curing agent as soon as possible onto the original
6. De-mold after 24 hours, it is will improve the replicate times of silicone mold.
Packing of Resin Casting Mold Making Silicones RTV-2 Rubber:
PAR A base Silicone: 5kg/pail, 20kg/pail, 25kg/pail or 200kg/pail.
PAR B catalyst ( curing agent ): 1kg/bottle.
Storage of Resin Casting Mold Making Silicones RTV-2 Rubber:
It is best for the mold if it can be stored in the original mold box or on a surface that will stress them the least. If left in a distorted shape for extended periods of time, the mold may not be able to return to the original state. Keep of out sunlight and in a cool, dry area if possible.
