Physical Indicators

CAS NO.:-- Density (25 ° C), g/cm3: 0.915 Boiling point:-- Flash point: ≥ 100 ° C Refractive index (nD20): 1.425 Appearance: Colorless transparent liquid Solubility: Soluble in conventional aliphatic and aromatic solvents such as alcohol, ether, benzene, etc; It is easily soluble in water, but at the same time, hydrolysis reactions occur.


Bifunctional silanes with reactive secondary amines and hydrolyzable silyloxy groups can enhance the interaction force between organic polymers and inorganic substrates and fillers, thereby improving the mechanical properties of composite materials; It can also be used for the preparation of structural adhesives, sealants, etc. Its unique molecular structure can endow the adhesive with better elasticity and tensile properties. Improve bending strength, tensile strength, impact strength, and elastic modulus to improve water resistance and corrosion resistance. The industries applied include: 1. The components of glass fiber and electronic cloth sizing agents; 2. Additives for casting resins such as phenolic resin, furan and melamine resin; 3. Primers, additives, or chemical modifications for adhesives and sealants; 4. Used as a pre-treatment agent for fillers and pigments in polymer systems containing inorganic fillers; 5. Used as a primer or additive to improve the adhesion of coatings or paints to the substrate; 6. Used for the modification of isocyanate silane in the production of SPU, or pre modified as a bonding promoter for isocyanate sealant.
