- General processing information GENIOSIL® GF 98 is very readily soluble in alcohols, esters and ketones. It is only slightly soluble in n-hexane. It may react slowly with ketones and aldehydes to form imines. With other alcohols excepting methanol, an autocatalytic exchange reaction forms mixed alkoxysilane bonds. In neutral water GENIOSIL® GF 98 reacts under hydrolysis and condensation of the silanol groups. The water has an approximate pH of 9 - 10.
- GENIOSIL® GF 98 as an Adhesion Promoter in Formulations In silane crosslinking formulations GENIOSIL® GF 98 may be added to the formulation as an adhesion promoter. Processing is effected by means of standard mixing methods. Usually, about 1 - 2 wt % silane is added to the formulation. GENIOSIL® GF 98 as a surface modifier Fillers are treated either with pure GENIOSIL® GF 98 or a solution thereof.
- It may be necessary to pretreat the substrate with water. In an alternative procedure referred to as "blending", GENIOSIL® GF 98 is added directly to the polymer - either before the organic materials is compounded with the filler or at the same time. However, this is only possible if the polymer is compatible with GENIOSIL ® GF 98. Important applications of GENIOSIL® GF 98 is the use as an adhesion promoter in sealants, adhesives and coatings, and as a coupling agent for inorganic particles, pigments or fillers.

- Typical Properties
- Properties
- Besides the application of GENIOSIL® GF 98 as an adhesion promoter in formulations and primers, it is also used as a coupling agent for modifying fillers and pigments to enhance dispersibility in organic binders and plastics, and thereby improve mechanical properties (flexural strength, tensile strength, modulus etc.).
- The compound reacts with moisture under hydrolysis of the alkoxy groups and forms silanols, which reacts further forming siloxanes. As a bifunctional amine, GENIOSIL® GF 98 can also interact with numerous organic polymers and thus function as a molecular bridge between organic and inorganic substrates.
