RTV2 Platinum Liquid Silicone Rubber For Molding

RTV2 Platinum Liquid Silicone Rubber For Molding

MCPLA-L20 Two-component addition type Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a Shore A20 rubber. The polymerization can be accelerated by heat. The silicone components are delivered as liquids, which once mixed and cured transform into a translucent, elastic and resistant material. Polymerization occurs without formation of heat.

Applications

Polyurethane, Epoxy resin and other reactive resins molds

Small pieces of cement,plaster,gypsum,concrete products.

Food like chocolate,fondants,desserts

Wax,candle,soap;

Low melt metal

Life casting,casting body parts,prosthetics.

Processing and Instructions of Addition Cure Silicones

1. Mixing the two components

According the mixing ration 10:1 or 1:1 weighting A and B, the two components may be thoroughly mixed either by hand or using a low-speed electric to minimize the degassing of bubbles and to avoid any temperature increase. Note: It is also possible to use a special mixing and dispensing machine for the silicone components, further information is available upon request.

2. Moulding

The mixture should be degassed preferably at 30 to 50 mbar to eliminate any entrapped air. If a dispensing machine is used, the two components are degassed separately prior to mixing. The silicone mixture expands to 3-4 times of its initial volume and bubbles rise to the surface. The bubbles progressively disappear and the mixture returns to its initial volume after 5 to 10 minutes. Wait a few minutes to complete the degassing and then flash the vacuum. The silicone is ready for pouring, either by gravity or under low pressure.

Note: Flashing the vacuum once or twice accelerates the degassing. It is recommended to use a container with a high diameter/height ratio (3 to 4 times of the initial volume)

3. Polymerisation

The curing may be slowed down at lower temperature or accelerated by applying heat.

Note:

Contamination from sulfur (e.g., sulfur-based clay), amines, tin compounds, cured polyester resin, some paints and some silicone rubbers may inhibit surface cure of platinum-cured rubbers.

Apply a release agent, Although not usually necessary, a release agent will make demolding easier when casting into most surfaces.

Storage and shelf life
MC Silicone MCPLA -H Series should be used within 12 months from the manufacturing date. Beyond this date, MC silicone no longer guarantees the products confirms with the sales Specification.
