Product Description
Addition Silicone Rubber For Cake Decoration Molds
Description of Addition Silicone Rubber For Cake Decoration Molds
MC Silicone MCPLA Addition Cure Series is a two component elastomeric cross-linking at room temperature. The polymerization can be accelerated by heat (max.1500 C). The silicone components are delivered as liquids, which once mixed and cured transform into a transparent, elastic and resistant material. Polymerization occurs without formation of heat.
Features of Addition Silicone Rubber For Cake Decoration Molds
Good flowability High tear and tensile strength Long shelf life with low shrinkage Fast mixing Easy processing due to the low viscosity
Applications
Label manufacturing, Molding applications requiring low shrinkage e.g., jewelry, automotive, plaster, cement decorations, toys and dolls, etc.

Processing and Instructions of Addition Cure Silicones
1. Mixing the two components
According the mixing ration 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: 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.
