Abstract：
SCA-K02W is a new type ograno-functional silane which contains 2 silyl groups, this unique structure enable it to have a better adhesion to dry/wet surfaces, stronger and weather resistance bond.
Applications and Performance：
1, 2-Bis(trimethoxysilyl)ethane (CAS No. 18406-41-2), Silane coupling agent SCA-K02W, has some application as below:
1. RTV silicone sealants: To enhance the adhesion to the dry or wet surfaces and could form a stronger and weather resistance bond.
2. Metal surface treatment: The toxic properties of chromates have caused an environmental demand on replacement of the chromium (VI) compound coating processes (chromating). One of the suggested methods is a silane coating. SCA-K02W with bis-silyl functional has six hydrolyzable groups and are believed to be more crosslinked than triand tetra-functional analogs. The enhanced crosslinking leads to better barrier properties in anticorrosion applications.
Packing：
The regular packing of this product is 25kg plastic pail, 200L steel drums and 1000L immediate bulk container.
Storage and Shelf Life：
Should be stored in dry, cool, ventilated room; keep away from water, moisture, high temperature and fire. This product has a shelf life of at least 12 months if stored in tightly closed original container at room temperature.
If this product is kept beyond the shelf life recommend on the product label, it is not necessarily unusable, but a quality control should be performed on the properties relevant to the application.
