GENIOSIL® UPTM
3-Ureidopropyltrimethoxysilane
GENIOSIL® UPTM is a clear liquid with a characteristic odor.
Properties
Besides the application of GENIOSIL® UPTM 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® UPTM is an alkoxysilane with
a functionalized amino group. It´s a clear, colorless to light yellowish liquid with a characteristically aromatic 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® UPTM can also interact with numerous organic polymers and thus function as a molecular bridge between organic and inorganic substrates.
Data sheets
1. General processing information
GENIOSIL® UPTM is very readily soluble in alcohols, esters and ketones. It is only slightly soluble in n-hexane. With other alcohols excepting methanol, an exchange reaction forms mixed alkoxysilane bonds. In neutral water GENIOSIL® UPTM reacts under hydrolysis and condensation of the silanol groups.
2. GENIOSIL® UPTM as an Adhesion Promoter in Formulations
In silane crosslinking formulations GENIOSIL® UPTM 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.
3. GENIOSIL® UPTM as a surface modifier
Fillers are treated either with pure GENIOSIL® UPTM or a solution thereof. It may be necessary to pretreat the substrate with water. In an alternative procedure referred to as "blending", GENIOSIL® UPTM 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® UPTM. Important application of GENIOSIL® UPTM is the use as an adhesion promoter in sealants, adhesives and coatings, and as a coupling agent for inorganic particles, pigments or fillers.
Packaging
GENIOSIL® UPTM is available in different packaging units:
- 200 KG Drum

Storage
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.
