Abstract：
SCA-U60E is a bifunctional organo-silane possessing a reactive organic ureido group and a hydrolysable inorganic triethoxysilyl group. The dual nature of its reactivity allows SCA-U60E to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers), thus functioning as an adhesion promoter and as a surface modifier. SCA-U60E is a 50% solution of silane in methanol is a colorless liquid with an alcohol-like odor and is soluble in alcohols, ketones, esters or aromatic hydrocarbons.
Applications and Performance：
3-Ureidopropyltriethoxysilane (CAS No. 23779-32-0), Silane coupling agent SCA-U60E, is an essential ingredient in the products of many industries. Examples are:
as a size constituent of finish for glass fiber/glass fabric composites
as an additive to phenolic, furan and melamine resins for foundry resins and abrasives
as an additive for sealants and adhesives
as an additive and/or primer for paints and varnishes to improve adhesion to the substrate
Important product effects that can be achieved through the use of SCA-U60E are:
improved mechanical properties: e.g. flexural strength, tensile strength, impact strength, modulus of elasticity
improved resistance to moisture and corrosion
higher temperature of deflection under load
SCA-U60E also helps improve processing properties such as increased filler content
Packing：
The regular packing of this product is 25kg plastic pail, 200L steel drums and 1000L immediate bulk container.
Storage and Shelf Life：
Should be stored in dry, cool, ventilated room; keep away from water, moisture, high temperature and fire. This product has a shelf life of at least 12 months if stored in tightly closed original container at room temperature.
If this product is kept beyond the shelf life recommend on the product label, it is not necessarily unusable, but a quality control should be performed on the properties relevant to the application.
