Abstract：
SCA-K01M is a monomeric alkylalkoxysilane with the shortest alkyl group that, when exposed to moisture, is an important component in sol-gel systems.
SCA-K01M is a colorless, low-viscosity liquid. Use requires acid- or alkali-catalysed hydrolysis. SCA-K01M is regarded as trifunctional since all three alkoxy groups are able to participate in this reaction. Additionally SCA-K01M contains a methyl group that adds organic character to the products. Hydrolysis leads to silanol groups which, in a subsequent condensation reaction, form very stable siloxane bonds (-Si-O-Si-).
Applications and Performance：
1. High-Performance Penetrating Sealers: Premium-grade penetrating sealers are easily formulated by blending 10 to 40 percent SCA-K01M in alcohols or organic solvents.
2. Sol-Gel system: It is an important component in Sol-Gel system.
3. Filler Dispersion: SCA-K01M can be used as a surface modifier to generate hydrophobicity (e.g. mineral fillers or inorganic pigments). The medium-chain alkyl functionality in unique compound properties when SCA-K01M treated minerals or pigments are incorporated into polymers e.g. PP, PE. Loading levels of 0.5 to 1.5 wt% SCA-K01M based on the weight of minerals or pigments are typically recommended.
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.
