Easy Demould Linear Shrinkage 1:1 A B Liquid Platinum Cure Silicone Rubber For Rapid Prototype Model Casting


Product description

Two-component addition type silicone rubber 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 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 (1:1)

Easy processing due to the low viscosity

39100000 Low Viscosity Linear Shrinkage 1:1 Two Component Silicone Rubber 0

Applications

Label manufacturing, Molding applications requiring low shrinkage e.g., jewelry, automotive, plaster, cement, cake decorations, 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.
