Dynasylan®

Dynasylan® IBTMO, an alkyltrialkoxysilane is an important surface modifier and component in sol­gel systems. Dynasylan® IBTMO, an alkyltrialkoxysilane is an important surface modifier and component in sol­gel systems. Dynasylan® IBTMO, an alkyltrialkoxysilane is an important surface modifier and component in sol­gel systems. Dynasylan® IBTMO is a colorless, low­viscosity liquid. Dynasylan® IBTMO is regarded as trifunctional since all three alkoxy groups are able to hydrolyze. Additionally Dynasylan® IBTMO contains an isobutyl group that adds organic character to the products. Hydrolysis leads to silanol groups which, in a subsequent condensation reaction, form very stable siloxane bonds (­Si­O­Si­). Condensation occurs parallel to hydrolysis once a certain amount of silanol groups have been formed. The absolute and relative rates of hydrolysis and condensation depend on a number of factors. The most important factors include pH, concentration, solvent, temperature and the catalyst.

Dynasylan® SIVO 408 is an oligomeric short-chain alkylfunctional silane. Dynasylan® SIVO 408 is a clear, colorless to slightly yellow liquid and soluble in common organic solvents (e.g. petroleum ether, toluene, alcohol). Because of its unique structure and viscosity Dynasylan® SIVO 408 is an easy-to-handle additive.

Dynasylan® 1146 diaminofunctional silane may be used in coatings, adhesives, and sealants to improve the adhesion of amino­reactive resins. These are resins such as silicones (RTV), two­part urethanes, silylated urethanes, MS polymers, and two­part epoxies to inorganic surfaces, plastic surfaces, and inorganic fillers. Dynasylan® 1146 silane is characterized by randomly­distributed linear and cyclic oligosiloxanes and fullfills the OECD polymer definition. Its low volatility and viscosity make compounding easy. Dynasylan® 1146 silane produces significantly less by- product (VOC) and has a correspondingly low odor level during application.

Dynasylan® 6598 is an oligomeric siloxane containing vinyl, propyl and ethoxy groups. Dynasylan® 6598 is a further development of Dynasylan®VTMOEO, vinyl-tris(2-methoxy ethoxy)silane. Dynasylan® 6598 is a colorless, nearly odorless low-viscosity liquid. Dynasylan® 6598 is an excellent silane compatibiliser between inorganic fillers (e.g. kaolin, MDH, ATH) and organic polymers (EPDM, EVA, PE).

Dynasylan® CPTEO functions as a surface modifier in CASE ingredients and plastics and elastomers.

Dynasylan® MTMS an alkyltrialkoxysilane is an important component in sol­gel systems. Dynasylan® MTMS is a colorless, low­viscosity liquid. Dynasylan® MTMS is regarded as trifunctional since all three alkoxy groups are able to hydrolyze. Additionally Dynasylan® MTMS 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 (­Si­O­Si­). Condensation occurs parallel to hydrolysis once a certain amount of silanol groups have been formed. The absolute and relative rates of hydrolysis and condensation depend on a number of factors. The most important factors include pH, concentration, solvent, temperature and the catalyst.

Dynasylan® SIVO 203 is a new multifunctional aminosilane adhesion promoter that can be used for a wide variety of applications. Dynasylan® SIVO 203 is mainly dedicated for use in adhesives and; sealants to improve the adhesion of hybrid products (e.g. silylated polyurethanes, MS Polymers), RTV-silicones, two-part polyurethanes and two-part epoxies to inorganic surfaces and some difficult plastic surfaces. In addition, Dynasylan® SIVO 203 can lead to fast sealant curing and high-crosslinked products and it imparts both additional flexibility and hydrophobicity.

Dynasylan® PTMO an alkyltrialkoxysilane is important component in sol­gel systems. Dynasylan® PTMO is a colorless, low­viscosity liquid. Dynasylan® PTMO is regarded as trifunctional since all three alkoxy groups can hydrolyze. Dynasylan® PTMO also contains a propyl group that adds hydrophobic character to sol­gel coatings. Hydrolysis leads to silanol groups which, in a subsequent condensation reaction, form very stable siloxane bonds (­Si­O­Si­). Condensation occurs parallel to hydrolysis once a certain amount of silanol groups have been formed. The absolute and relative rates of hydrolysis and condensation depend on a number of factors. The most important factors include pH, concentration, solvent, temperature and the catalyst.

Dynasylan® F 8261 is a bifunctional silane possessing hydrolyzable inorganic ethoxysilyl groups and a fluoroalkyl chain. Dynasylan® F 8261 acts as a surface modifier on mostly hydroxyfunctional substrates (e.g. glass, ceramic). It can also be used as an adhesion promoter between inorganic materials and fluoropolymers (PTFE, fluorosilicones etc.). Dynasylan® F 8261 is a colorless and odorless liquid. It can be diluted to a proportion of about 25 wt.% in ethanol and various other organic solvents, e.g. n-hexane, xylene, acetone or ethyl acetate.

Dynasylan® SIVO 160 is a water­borne storage stable silane based sol­gel system for the formulation of inorganic surface treatment primers. As part of the SIVO® SOL Technology, it features all the benefits of the other well established products of this series. These are the absence of heavy metals, fluorides, and solvents. It is designed to have a low volatile organic content. Due to its polymeric nature, it is characterized by a high reactivity. This is demonstrated by its extraordinary low curing temperature of 20 to 80 °C which represents a major breakthrough for water­borne sol­gel systems. Dynasylan® SIVO 160 is a clear to slightly opaque, colorless to slightly yellow, low viscosity liquid.

Dynasylan® F 8815 is a fluoroalkylfunctional water-borne oligosiloxane which acts as a surface modification agent on oxidic, carboxy- and hydroxyfunctional substrates for example ceramic, natural fibers like cotton or leather. Dynasylan® F 8815 is a yellowish, slightly turbid liquid. The product can be mixed with water to any desired concentration.

Dynasylan® 1124 is a secondary aminofunctional methoxy- silane possessing two symmetric silicon atoms. Dynasylan® 1124 acts as an adhesion promoter between inorganic materials (for example glass, metals and fillers) and organic polymers (thermosets, thermoplastics and elastomers), as a surface modifier and can be used, for the chemical modification of substances. Dynasylan® 1124 is a colorless to yellow liquid with an amine-like odor, which is, for example, soluble in alcohols, aliphatic or aromatic hydrocarbons.
