3-Glycidoxypropyltrimethoxysilane (GLYMO) | Manta E560

Manta E560 is γ-glycidoxypropyltrimethoxysilane (GLYMO, CAS 2530-83-8), an epoxy-functional silane used as a coupling agent, surface modifier and adhesion promoter in coatings, sealants, mineral-filled polymers, fiberglass sizing and copper clad laminates for PCBs. It offers non-yellowing adhesion and better storage stability in 1K polyurethane systems than amino silanes.

Overview

Manta E560 is an epoxy-functional organosilane with a reactive glycidoxy (epoxy) group and hydrolyzable trimethoxysilyl groups. This dual-reactive structure allows it to bond chemically to both inorganic substrates, such as glass, metals and minerals, and organic polymers, such as epoxies, polyurethanes and acrylics.

Unlike amino silanes, E560 provides good non-yellowing characteristics and storage stability in reactive polymer systems. In single-component polyurethane and SPUR systems it helps to avoid the premature crosslinking or gelling seen with traditional amino silanes. In heavily mineral-filled plastics and composites it lowers resin viscosity, improves filler dispersibility and enables higher filler loading.

E560 is the trimethoxy epoxy silane in the range. Manta E563 is the methyldiethoxy grade, which releases ethanol rather than methanol and reduces crosslink density for flexible systems. Manta OP200 is a pre-condensed oligomer that reduces alcohol release during curing.

Key Features

  • Improved shelf-life stability in 1K polyurethane and SPUR systems compared with traditional amino silanes
  • Adhesion without the yellowing associated with primary or secondary amine adhesion promoters
  • Lowers resin viscosity in heavily mineral-filled plastics and composites, enabling higher filler loading
  • Increases flexural strength, tensile strength and modulus of elasticity
  • Improves resistance to water, vapor, acids and bases
  • Releases methanol on hydrolysis

Frequently Asked Questions

Why choose Manta E560 over an aminosilane in 1K polyurethane systems?

E560 offers improved shelf-life stability in single-component polyurethane and SPUR systems, helping to avoid the premature crosslinking or gelling associated with traditional amino silanes. It also gives adhesion without the yellowing typical of amine adhesion promoters.

What does Manta E560 do in copper clad laminates and PCBs?

It surface-treats electronic-grade fiberglass cloth to bond the epoxy resin matrix tightly to copper foil, giving resistance to high-temperature wave soldering without delamination. It is also added to epoxy molding compounds for semiconductor encapsulation, where it helps to limit moisture penetration.

How does Manta E560 affect heavily filled resin systems?

It lowers resin viscosity in mineral-filled plastics and composites, improves the dispersibility of fillers such as silica, talc and clay, and enables higher filler loading, while increasing flexural strength, tensile strength and modulus.

Which substrates benefit most from an E560 primer?

Challenging substrates such as glass, aluminum and steel, where it improves both wet and dry adhesion of paints and coatings. It is also used as a primer or internal additive in epoxies, polysulfides and polyurethanes to enhance substrate bonding.

What shelf life applies to Manta E560?

Keep away from heat and open flame. When stored at or below 25°C in the original unopened containers, this product has a usable life of 24 months from the date of production (200L drum). It is supplied in 25 kg pail, 200 kg drum and 1000 kg IBC.
