Platinum Cured Translucent RTV2 Liquid Silicone Rubber for Food Molds

MC Silicone platinum silicone rubber, also known as addition-cure silicone mold rubber, platinums exhibit the lowest long-term shrinkage (0.01% )and have long library life . The silicone are delivered as two-component liquids, which once mixed and cured transform into a translucent, elastic and resistant material. The polymerization can be accelerated by heat.

Features:
Non-toxic food grade
Application:
1.A range of materials can be cast into the cured silicone mold:
polyurethane and other reactive resins
Small pieces of cement,plaster,gypsum,concrete products.
Food like chocolate,fondants,desserts
Wax,candle,soap;

2.casting body parts, artificial skin, silicone dolls ,shoe insole.

TYPICAL PROPERTIES of liquid silicone rubber

INSTRUCTIONS for addition cure silicone rubber

1. Mixing the two components
According the mixing ratio 1: 1 weighting part A and B, the two components may be thoroughly mixed either by hand or using a low speed electric to minimize the entrance of air and to avoid any temperature increase.
Note: It is also possible to use a special mixing and dispensing machine for the two silicone components, further information is available upon request.

2. Molding
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 to 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. Polymerization
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 elastomeric is catalyzed with metal salts, e. G. Tin compounds
PVC stabilized with tin salts and additives
Epoxy catalyzed with amines
Certain organic solvents, such as Ketones, alcohols etc.

In case of doubt, it is recommended to test the substrate by applying a small quantity of the mixed silicone on a restricted area.
