Description of RTV2 silicone for resin ornaments molding
Condensation cure, tin cure liquid silicone, RTV 2 mold making silicones are generally named as two-part silicone rubbers which vulcanise, or cure, at room temperature. Part A is a dynamic liquid silicone/Part B is the curing agent (tin catalyst).
Main applications of RTV2 silicone for resin ornaments molding
Construction of moulds for gypsum, soap, candles, concrete, resin products, artificial (very lightweight) stone, wax or custom moulds;
Decorative building moulds (cornice, column, balustrade, ceiling roses, pedestals, fountains, mantels, wall ornament, planter etc;
Resin crafts, epoxy resin crafts, poly resin crafts, polyester resin.
Advantages of our RTV2 silicone for resin ornaments molding
Exceptional fluidity and good operability, easy to demold.
Cures at room temperature within 3-4 hours (assuming constant temp of 25 degrees C).
Good tensile and tear strength, low shrinkage (<0.3%)
High duplication levels or longevity
Good resistance to weather, temperature, aging, acid.
Long shelf life (12 months at least) if kept at constant temperatures.
STORAGE of Molding RTV-2 Silicone Rubber:
When the silicone rubber is stored at or below 30 ° C (85 ° F) in the original unopened containers, RTV2 Silicone Base and CA30 Curing agent have a usable life of
12 months from the date of production. After
12 months stockpiles use the Stir to mix the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.
Professional factory of RTV-2 Molding Silicone:
We are manufacturer, and specialized in manufacturing different hardness, different viscosity silicone rubber series, we are competitive in price with good quality.
