RTV-2 condensation cure silicone rubber ( RTV-2 silicone )

Main applications of RTV-2 condensation cure silicone rubber:

RTV-2 is mainly used for making molds for duplications for the industries such as Poly resin, epoxy poly-resin, plaster crafts, soap crafts, candles crafts, lighting, architectural decorations, embossed furnitures, plastic toys, gifts and stationeries, large statues.

Features of our RTV-2 condensation cure silicone rubber

low viscosity,

good fluidity,

high tensile and tear strength,

produced by molds can be used repeatedly, longer life expectancy.

Operations of RTV-2 condensation cure silicone rubber :

(1) Brushing cast or Perfusion Molding operation

a.Carefully wash the original mold , then dry it with an air gun. Then brush some release agent such as soap water, detergent,vaseline,liquid wax ,etc..

b. Evenly brush the mixed silicon rubber on the product which is covered with mold spray with a brush or a brush pen.

c. After the cross linking reaction (about 30 minutes), brush a second coat which can increase the tension and tear strength of the mold.

d. Cover a glass cloth on it after another 30 minutes of a second cross linking reaction, and use a brush pen or a brush to avoid any interstices.

e. Cover a third coat.

(Note: if you have high requirements for the tension and the tear strength for the mold, please repeat step c and step d. Hence, the finished silicone moulds will have a good quality and a longer life, which can help you save cost and increase production efficiency.)

(2) Pouring moulding:

It is suitable for simple products with the smooth surface. Without any mold lines, which helps you save time and is easy for operation. Evenly and slowly perfuse the mixed silicone rubber into the square fram. After the cross linking reaction and the silicone rubber turns dry,you can take the products out. Thus, the mold has been done.

(Note:we usaully use soft silicone rubber to make molds by perfusing, which is easy for demoulding and will not damage the product in the silicone molds.)
