Product description of Platinum Liquid Silicone

Two-component addition type silicone rubber Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a Shore A 0~55 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 of Platinum Liquid Silicone

Convenient to operate with the RTV property

Easy to mix due to the low viscosity (7000~9000Cps)

Can be accelerated by heat for rapid cure

High duplication because of high tear and tensile strength

Long shelf life of 12 months

Odorless,Skin safe, Food safe

 

Applications of Platinum Liquid Silicone

1. A range of materials can be cast into the cured silicone mold:

polyurethane and other reactive resins

Small pieces of cement,plaster,concrete products.

Food like chocolate,fondants

Wax,candle,soap;

Low melt metal

2. Label manufacturing, toys, jewelry, automotive, rapid prototyping etc.


Processing and Instructions of Addition Cure Silicones

1. Mixing the two components

According the mixing ration 10:1 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:

1. 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.

2. Apply a release agent, Although not usually necessary, a release agent will make demolding easier when casting into most surfaces.

Storage and shelf life

When the silicone rubber is stored at or below 25 degree Celsius in the original unopened containers, Silicone Base and Curing agent have a usable life of 12 months from the date of production. After 12 months’ stockpiles, please use tool to stir the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.

1. Store the original packing tightly sealed and at a temperature below 25 degree Celsius.Use the product as soon as the packaging has been opened.

2. Close the lid tightly after taking out the proper amount of liquid silicone rubber.Use the product as soon as the packaging has been opened.
