Pourable ,Condensation Cure Mold Making RTV2 Silicone Rubber
Condensation tin cure molding silicone rubber, Tin-based silicone, also called condensation-cure silicone, are two-component materials which cure at room temperature (RTV) to flexible, high tear-strength rubbers. Tin cured silicone can be poured onto models or they can be made brush-able by adding a Thixotropic additive. They are ideal for molds where easy release or high temperature resistance is required.
Condensation Cure Mold Making RTV2 Silicone Rubbers can be poured or brush onto products for casting polyurethane,epoxy, polyester resin, gypsum/plaster, cement, waxes, low melt alloys/metals, etc.
• Low Shore A hardness (approx. 20)
• Excellent tear strength
• Very high elongation and flexibility
•Little rate of deformation and shrinkage
• High temperature resist,high tear resist

Mixing Ratio By Weight
Pot life Time
If mix 0.5%-1% ratio of RTV2 silicone Antioxidant agent into silicone rubber, it can great increase using times about 30%-100%, and casting resins resist, particularly polyesters.
Thickening agent for silicone rubber for vertical surface application(making brush-on molds)
Preparing the Model
Porous surfaces, such as wood, should be dried and sealed. Also applying a release agent, such as petroleum jelly will aid in easy release of a silicone mold. Because silicone can sometimes bond to surfaces which contain silica, such as glass, cements and natural stone; it is recommended to do a spot test for possible adhesion.

The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
Silicone Base is available in 1kg/5kg/20kg/25kg/200kg plastic/iron drum.Curing Agent is available in 0.25kg,1kg,5kg and 25kg plastic/iron drum.Vacuum bag can be used according to users demand.
Avoid contact with mucous membranes and eyes. Best method of cleanup is by wiping with disposable paper towels and washing with waterless hand cleaner, then soap and water. If solvents must be used, denatured ethyl alcohol is best, but should be handled with respect for health and flammability hazards.
