Liquid silicon rubber for concrete mold

1. Applications of Liquid silicon rubber for concrete mold

Liquid silicon rubber can be used to cast a variety of materials including wax, gypsum, low melt alloys/metals and urethane, epoxy or polyester resins.

The following mouldings can be reproduced and cast by liquid Silicon Rubber:architectural bracket mouldings,

decorative garden resin statue mouldings, gypsum plaster ornament mouldings, cornices, round corners, corbels mouldings, ceiling roses, medallion mouldings, pilaster and balustrade mouldings, art sculpture mouldings, quick prototyping, precision castings, art sculpture molds, landscape mouldings, precast stone mouldings and so on.

2. Features of Liquid silicon rubber for concrete mold:

Liquid Silicon rubber for mold making is white or red flowing liquid with general hardness of 22-50A°after curing. Molding silicon rubber is a kind elastic silicon rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength ,tear strength and elongation. Our curing agent is free charged.

3. Process operations of Liquid silicon rubber for concrete mold:

Liquid silicon rubber molds are the least expensive and fastest way to create about a dozen prototype parts. As shown in the figure below, even with undercuts, the part is able to be removed through distortion of the mold.

a. Process and prepare the model mold or the product to be duplicated,

b. Take certain amount of the silicon rubber, add 2-3% solid curing agent, and mix evenly and they are ready for use.

c. Once cured, the RTV is removed from the vat and separated from the pattern and parting line surface to yield the two halves of the molding tool. RTV air-cures, so that the cure time depends on the geometry, the RTV type, and the environment. Cure time can range from .5 to 40 hours. Aging of the mold after cure for up to three days can improve mold lif
