Product Description

RXSILICONE RX-825

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.

Antioxidant Agent

RTV2 silicone Antioxidant agent,mix ratio with silicone rubber at 0.5%-1%,it can great increase about 30%-100% using times of silicone mold and make the silicone rubber with high heat resistance and solvent resistance.
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.
