Translucent Platinum Liquid Silicone RTV2 Silicon Molding Rubber For Food Molds

MCPLA-L25A/B are platinum-cured (also known as addition-cure), room temperature-curing silicones that cure to flexible, high-strength rubbers. MCPLA-L25A/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, 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.
