Good Flowability Easy To Use 1:1 Mix Ratio Platinum Cure Silicone Rubber For Making Cake Decoration Molds
Two-component addition type silicone rubber , liquid silicone rubber is a two component elastomer cross-linking at room temperature. The polymerization can be accelerated by heat. 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 High Transparency High tear and tensile strength Long shelf life with low shrinkage Fast mixing (10:1) Easy processing due to the low viscosity Applications Label manufacturing, Molding applications requiring low shrinkage e.g., jewelry, automotive, plaster, cement, cake decorations, etc.
Technical Properties
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: 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. Packaging 20kg per drum, 200kg per drum
