Components A and B are supplied ready for use in 20 kg pails and 200 kg drums. They can be pumped from the drums using standard metering equipment, mixed via a static mixer, and directly injected into the heated mold. The mixing ratio is 1:1 by weight.
Silicone rubber should be stored at room temperature in a dry and well-ventilated environment. In warm climates, storage in an air-conditioned warehouse under cool (below 25°C) and dry conditions is required.
The recommended storage period is twelve months. Storage beyond this period does not necessarily render the product unusable; however, the relevant properties for the intended application should be verified for quality assurance purposes.
Vulcanization time varies with the production method and product thickness, and should be adjusted as required for different applications.
Avoid contact with nitrogen-, phosphorus-, sulfur-, or tin-containing materials, which may hinder vulcanization.
Users are responsible for understanding the intended applications and proper use of products. These products are not intended for implantation or injection into the human body.
Due to variations in testing and production conditions, we cannot guarantee identical test results. Users are advised to use data obtained under their own testing conditions as a reference for performance.
The above performance data and usage recommendations are for reference only and do not guarantee the effectiveness or applicability of DONGGUAN JINGSHUO SILICONE MATERIALS CO.,LTD products in specific applications.mobile:010-123456798
