RTV2 Addition Cure Liquid Silicone Mold Rubber For Concrete Mold Casting 40 Shore A

Mold Making RTV2 Liquid Platinum Cure Silicone Rubber For Mold Making

DESCRIPTION
RTV silicone rubber is a two component 1:1 elastomeric cross-linking at room temperature. The polymerization can be accelerated by heat (max. 150 C). The silicone components are delivered as liquids, which once mixed and cured transform into a elastic and resistant material. Polymerization occurs without formation of heat.

Item No.	MCPLA-L40A/B
Appearance	Viscous liquid
Color	Translucent
Viscosity ( cps,approx.)	7000-9000
Mix ratio (A:B)	1:1
Working time(at 25℃ ,minutes)	30-40
Curing time(at 25℃,hrs,approx.)	4-6
Hardness Shore A(after 24 h)	40
Tensile Strength(Mpa,after 24 h)	3.8
Elongation(%)	510
Tear Strength(N/mm)	17
Linear Shrinkage (%)	0.1

ADVANTAGES
Custom color
Convenient to operate WITH the RTV property
Easy to mix due to the low viscosity (7000~9000Cps)
High duplication WITH high tear and tensile strength
Long shelf life with low shrinkage
Excellent chemical resistance
Can be accelerated for rapid cure

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.
