Product description of 10:1 RTV2 liquid addition cure molding silicone rubber for crafts molds
MC Silicone MCPLA-H40 is a two-component elastomeric material consisting of Silicone Base, which when mixed with Curing Agent,cures to an elastic and resistant material at room temperature by an addition reaction. The curing can be heat accelerated. A range of materials can be cast into the cured silicone mold.
Features of 10:1 RTV2 liquid addition cure molding silicone rubber for crafts molds
High Transparency
Good flowability
High tear and tensile strength
Long shelf life with low shrinkage
Fast mixing (10:1)
Flexible and dimensional stability
Applications of 10:1 RTV2 liquid addition cure molding silicone rubber for crafts molds
Label manufacturing, hearing aid earmold, molding applications requiring low shrinkage e.g., jewelry, automotive. It can be used to make exceptionally strong and tear resistant molds for casting wax, resins and other materials, etc.

Processing and Instructions
1. Mixing the two components
According the mixing ration 10:1 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: in general contact with certain materials can inhibit the cross linking of RTV.
Natural rubbers vulcanized with sulfur
RTV silicone compound catalyzed with metal salts, e.g. Tin compounds
PVC stabilized with tin salts and additives
Epoxy catalyzed with amines
Certain organic solvents, e.g. Ketones, alcohols, etc.
In case of doubt, it is recommended to test the substrate by applying a small quantity of the mixed silicone on a restricted area.
