Features and application:
1. Addition cure type
2. Good operability, high tear strength
3. No oil migration and excellent chemical resistance
4. Suitable to make molds for casting of culture stone, sand stone and artificial stone.
INTRODUCTION:
We are a leading Chinese manufacturer of RTV(room temperature vulcanized) liquid silicone rubber for mold making, which is widely applicable to multipule fields and purposes, including candle casting, resin casting, polyurethane casting, gypsum product reproduction, lifecasting, food casting, metal casting, concrete casting, etc.
Our RTV silicone rubber for mold making, is normally of milkwhite color and in a viscous liquid state. It is composed of 2 parts(A: Silicone rubber, B: Curing agent). When the 2 parts are mixed in a proper ratio and applied to the model in room temperature, the liquid rubber would cure into solid state within a "curing time", which is adjustable depending on the user's requirements.
Our silicone rubber falls into 2 categories, namely addition cure(platinum-cured) and condensation cure(tin- cured). For each category, we have different items of different hardness, viscosity and curing time to cater to different users' requirements. Users can use it for different operations like pouring molds and brushing molds etc.
Advantages:
1. Good fluidity. Ensures convenience of operation.
2. High tear resistance strengh, which promises many times of reproduction without damage to the mold.
3. Low shrinkage, which enables you to precisely cast your products without deformation.
4. Non-toxic, with FDA certificates.
Hardness(shore A):
When it comes to choosing proper hardness and viscosity, usually lower hardness and viscosity is recommended for casting of small-sized products with intricate features, and higher hardness and viscosity is recommended for casting of simple or big-sized products. Our product's hardness ranges from shore 10A to 50A to meet customers' different requirements.
Different colors: As some customers may need to make colored molds, we also have our own pigments to match with the silcone rubber. If need be, it will be our pleasure to sell you colored silicone rubber, or you may do the dying process by yourselves. Just choose the best way for you.
Free sample: Considering many customers' need of testing before purchasing, we usually offer 1kg of sample to you for trial free of charge.
Below is a general use guidance for our RTV silicone rubber:
TECHNICAL GUIDELINES:
1. Weigh a desired amount of liquid silicone rubber (part A) and curing agent(part B), and mix them evenly by stirring.
2. Put the mixture into a vacuum chamber for deaerating. Keep it in the vacuum chamber for about 2-5 minutes, depending on the amount of silicone rubber. Make sure the container is bigger than the silione rubber volume, because the mixture must expand to give off bubbles.
3. Pouring the deaerated mixture over the highest point of the master model to form a casting mould;
4. Demold after the liquid silicone rubber cures thoroughly.
