Product Description
Product Brief introduction of RTV liquid silicone molding compounds
RTV liquid silicone rubber is the a kind of room temperature vulcanized molding compounds with two parts, Part A is the silicone rubber base and part B is the condensation cure hardner, which are in mixing ratio of 100:3 and with features of:
• Easy for operation
• Reproduce intricate details
• Resist tearing with repeated use
• Provide good resistance to most chemicals
• Offer variable cure times at room temperature
• Flexible to reduce de-molding and stress problems
• High duplication times(e.g.800-1000times for gypsum products)
Title goes here.
• Artificial stone products molding, Wax casting
• Making molds for gypsum, GRC, concrete, resin products etc
• Casting for Statue, Buddha, Christmas ornaments, sculptures, figures
• Unsaturated rein crafts, epoxy resin crafts, poly resin crafts, polyester resin
•Decoration building mold making (cornice, column, balustrade, ceiling, pedestals, fountains, mantels, wall ornament, planter, furniture decorative etc.)

Main Application: XB-730# is in the hardness of about 30 shore A, then the application of XB-730 would be used to make mould of the products in medium size such as 40~50cm with simple patters, such as the concrete/cement/stone products, plaster line/conics, concrete stamping, garden statues, gypsum decoration, plaster ornaments, fiberglass products, polyester decoration, unsaturated resin crafts, poly resin crafts, polyurethane, bronze, wax and similar products.
Packing & Delivery
Gernal package of platinum cure silicone rubber
The mixing ratio of the platinum cure/additional silicone rubber is 1:1, so the part a and part b would be half.
Gernal package of tin cure silicone rubber
The mixing ratio of tin/condensation cure silicone rubber is 100:3, thus 3% catalyst would be offered for free. And if you dont want the plastic bags in side, catalyst would be sent in extra drums.
