Translucent Liquid Platinum Cure Silicone Rubber RTV2 Silicone For Soap Candle Mold
|
Platinum Cure Translucent Liquid Silicone Rubber RTV2 Silicone Raw Material For Soap, Candle Mold MakingMCPLA-L20A/B are platinum-cured (also known as addition-cure), room temperature-curing silicones that cure to flexible, high-strength rubbers. MCPLA-L20A/B molds offer excellent release properties and release agent is not necessary when casting most materials. Features High tear and tensile strength Long shelf life with low shrinkage Fast mixing (1 :1) Easy processing due to the low viscosity Self-release properties Bubble Free Food safe, Skin safe,Eco-friendly
Applications Molding applications requiring low shrinkage e.g., jewelry, automotive, plaster, cement, cake decorations,food molds, Soap, Candle molds,etc.
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 -L 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. In order to preserve best properties it is recommended to follow strictly the following guild lines: Store the original packing tightly sealed and at a temperature below 30 degree Celsius. Use the product as soon as the packaging has been opened. Packaging 20kg per drum, 200kg per drum
