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.

Applications

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.

 

Features 

• 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

Antioxidant Agent

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.

Thixotropic agent

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.
