Glycidoxypropylmethyldiethoxysilane | Manta E563

Manta E563 is a bifunctional epoxy organosilane with a reactive glycidoxy group and a methyldiethoxy silyl group. Compared with standard tri-alkoxy silanes, this structure offers two formulation differences: it releases ethanol on hydrolysis, and its dialkoxy structure reduces crosslink density, acting as a flexible chain extender rather than a rigid 3D crosslinker.

E563 is an adhesion promoter for water-borne systems. It is stable in aqueous environments and improves both dry and wet adhesion in water-borne acrylic sealants and coatings without sacrificing the elongation and flexibility of the cured polymer. It also imparts adhesion without the yellowing typically associated with amino silanes.

Compared with Manta E560, the trimethoxy epoxy silane, E563 releases ethanol rather than methanol and builds a less densely crosslinked network, which keeps sealants and adhesives flexible. E560 is used in mineral-filled polymers, fiberglass sizing and copper clad laminates.

• Water-borne sealants and coatings: adhesion promoter for water-borne acrylic sealants, polyurethanes and epoxies, improving wet adhesion to glass and metals
• Water-borne finishes: internal crosslinker and adhesion promoter in polyurethane dispersions and water-borne acrylics, especially wood and industrial metal finishes, improving mar resistance, chemical resistance and wet adhesion without embrittling the cured film
• Electronic encapsulants: improves wet electrical properties and moisture resistance of epoxy-based encapsulants and packaging materials
• Low-stress potting compounds: flexibilizer that reduces crosslink density, minimizing shrinkage and thermal mechanical stress on wire bonds and components
• Reduced-primer sealants: reduces the need for a separate surface primer in high-movement polysulfide and polyurethane joint sealants
• Composites and fiberglass: improves dry and wet mechanical strength in composites reinforced with glass fiber rovings
• Anti-corrosion metal primers: primers for steel and aluminum, improving salt-spray resistance and helping to limit cathodic delamination and blistering

Supplied in 200 kg drum and 970 kg container.
