1-[3-(Trimethoxysilyl)propyl]urea CAS 23843-64-3

Introduction

3-Ureapropyl trimethoxysilane can be used as a metal surface rust inhibitor with special effects. It can be used to treat the surface of gold, silver, copper and other metals to improve their corrosion resistance, oxidation resistance and adhesion to polymer materials. It is widely used in filling polymer materials and can be applied to thermosetting and thermoplastic polymer materials, such as epoxy, nitrile, phenolsulfonate, polyvinyl chloride, polystyrene, polysilicon, etc.

Specification 

Application

1. Used as an additive or as a primer for phenolic, urea-formaldehyde, furan, polyurethane, silicone, epoxy, phenolic, acrylic and other coatings, inks, adhesives and sealants to improve the adhesion, corrosion resistance, weather resistance, water boiling resistance and scrub resistance of resin coatings, extend service life, and improve the dispersion and bonding of pigments and fillers in the resin phase.

2. Used in resin abrasives to improve the bonding strength and water resistance of resin and abrasives, and extend the service life of the product;

3. This product can significantly improve the bonding strength and sand strength of cold core box casting resin, and can reduce the amount of resin and gas generation while maintaining the strength of the sand, improve the quality of castings, and reduce the scrap rate ;

4. It is suitable for inorganic materials including glass, glass fiber, glass wool, mineral wool, mica, quartz and other siliceous materials and aluminum hydroxide, magnesium hydroxide, kaolin, talc, steel, zinc, aluminum and other metals and their oxides, but it has little effect on fillers that do not contain hydroxyl groups on the surface such as calcium carbonate, graphite, carbon black, barium sulfate;

5. It is suitable for polymers including (but not limited to) phenolic, epoxy, furan, urea-formaldehyde, melamine, polyurethane, acrylic, polyester, silicone, nitrile and other resins and nylon, PBT, PET, EVA, PP, PE, PVC, PVB, PVAC, PS and other plastics;

6. As an adhesion promoter for alcohol-based RTV silicone rubber, it can significantly improve its storage stability.
