- Dynasylan® IBTMO silane is used as a surface modifier to generate hydrophobicity (e.g. in inorganic pigments, mineral fillers). The short-chain alkyl functionality results in unique compound properties when Dynasylan® IBTMO-treated minerals or pigments are incorporated into polymers, e.g. polyethylene or polypropylene.
- Recommended Usage: Loading levels of 0.5 to 1.5 weight-% Dynasylan® IBTMO based on the weight of filler or pigment are typically recommended.
- Application: Dynasylan® IBTMO is excellent as a dispersion and hydrophobation agent in mineral-filled compounds. In the presence of moisture, the methoxy groups of Dynasylan® IBTMO hydrolyze to produce methanol and reactive silanol groups. These silanol groups react with the filler via silicon-oxygen bridges. Dynasylan® IBTMO can be used in many other applications, such as filler and pigment coatings, dispersions, etc.
Typical Property Improvements:
- Improved filler dispersion
- Good processability
- Significantly reduced water-uptake
- Strongly reduced stress cracking
Dynasylan® IBTMO is also an important starting material for sol-gel processes. It adds a certain amount of organic character to the siloxane network due to the isobutyl group in the product. Dynasylan® A (tetraethoxysilane) is often used in conjunction with Dynasylan® IBTMO to control the amount of inorganic character of the inorganic network.In some sol-gel applications, Dynasylan® IBTMO is partially hydrolyzed to form a pre-product that can be further hardened using temperature.
