Aminoethylaminopropyltrimethoxysilane | Manta A112

Manta A112 is a bifunctional organosilane with two reactive amino groups, primary and secondary, and one hydrolyzable trimethoxysilyl group. Its 2-aminoethylaminopropyl structure provides higher bond strength to difficult inorganic and organic substrates than standard mono-amino silanes.

A112 reduces filler sedimentation tendencies, improves dispersibility and enhances the mechanical and electrical properties of composites and sealants. In many sealant systems it can reduce the need for separate surface primers, and in polysulfide sealants it produces cohesive failure in the sealant rather than adhesive failure at the interface.

Compared with the mono-amino grades Manta A110 and Manta A111, A112 adds a secondary amine for crosslinking with organic resins. Manta A112T is the technical-grade version with an active content of 85% min., designed for faster dispersion into high-viscosity resins.

• RTV silicones and hybrid sealants: improves adhesion to glass, steel, aluminum and concrete in one- and two-part silicone-crosslinked sealants, and to a wide array of plastics in combination with silylated polyurethane (SPUR) technology
• Polysulfide sealants: adhesion to glass, aluminum and steel in one- and two-part systems, producing cohesive failure in the sealant rather than adhesive failure at the interface
• Plastisol sealants: replacement for polyaminoamide adhesion promoters, improving bonding to metal while keeping a very light color and a bubble-free cured compound
• Paints and coatings: internal adhesion promoter and crosslinker in 2K epoxy and 2K polyurethane heavy-duty protective coatings, improving inter-coat adhesion and anti-corrosion, salt-spray and chemical resistance on metal
• Glass fiber and mineral wool: sizing and finishing agent that improves flexural and tensile strength and helps to protect the interface from moisture degradation
• Foundry and abrasives: additive to phenolic, furan and melamine resin binders, increasing sand core strength and durability, and enhancing the bond between abrasive grains and resin in grinding wheels
• Phenolic and epoxy molding compounds: reduces water absorption of molded composites and improves wet electrical properties such as volume resistivity and dielectric constant

Supplied in 25 kg pail, 200 kg drum and 1000 kg IBC.
