GENIOSIL® 9201
3-Ureidopropyltriethoxysilane in Methanol
GENIOSIL® 9201 is a clear liquid with a characteristic odor with an active silane content of 50 % (w/w).
- CAS编号 23779-32-0
- 实验式 C10H24N2O4Si
- 分子量 264,39 g/mol
特性
Besides the application of GENIOSIL® 9201 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.). GENIOSIL® 9201 is an alkoxysilane with
a functionalized amino group, dissolved in Methanol. It´s a clear, colorless to light yellowish liquid with a characteristically odor. The compound reacts with moisture under hydrolysis of the alkoxy groups and forms silanols, which reacts further forming siloxanes. As a bifunctional alkoxysilane, GENIOSIL® 9201 can also interact with numerous organic polymers and thus function as a molecular bridge between organic and inorganic substrates.

1. General processing information
GENIOSIL® 9201 is very readily soluble in alcohols, esters and ketones. It is only slightly soluble in n-hexane. With higher alcohols an exchange reaction forms mixed alkoxysilane bonds. In neutral water GENIOSIL® 9201 reacts under hydrolysis and condensation of the silanol groups.
2. GENIOSIL® 9201 as an Adhesion Promoter in Formulations
In silane crosslinking formulations GENIOSIL® 9201 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 which would be equivalent to 2 - 4 % of the diluted silane in GENIOSIL® 9201.
3. GENIOSIL® 9201 as a surface modifier
Fillers are typically treated with pure GENIOSIL® 9201 as it is already diluted in Methanol It may be necessary to pretreat the substrate with water. Important application of GENIOSIL® 9201 is the use as an adhesion promoter in sealants, adhesives and coatings, and as a coupling agent for inorganic particles, pigments or fillers.

储存
The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
