Epoxy Silane Oligomer | Manta OP200
Manta OP200 is an epoxy-functional silane oligomer used as a crosslinker and adhesion promoter in industrial, automotive, marine and architectural coatings, structural adhesives and sealants. Its pre-condensed structure carries significantly fewer hydrolyzable alkoxy groups than monomeric epoxy silanes, reducing alcohol emissions during processing and curing and improving hydrolytic stability.

Overview
Manta OP200 is an epoxy-functional silane oligomer with a pre-condensed polymeric structure. This oligomeric network significantly reduces volatile organic compound (VOC) emissions during curing and improves hydrolytic stability.
It acts as a cross-linking agent and adhesion promoter designed for compatibility across water-borne, solvent-borne, high-solids and solvent-free formulation systems. The pre-formed siloxane network promotes dense cross-linking, which enhances the wet scrub resistance, chemical resistance and anti-corrosion properties of cured films.
OP200 differs from the monomeric Manta E560 in its pre-condensed structure. It contains significantly fewer hydrolyzable alkoxy groups, so less alcohol is released during processing and curing, and it shows lower sensitivity to premature moisture hydrolysis in formulated systems.
Key Features
- Pre-condensed oligomer with significantly fewer hydrolyzable alkoxy groups than standard monomers
- Low-VOC profile, minimizing alcohol emissions during processing and curing
- Designed for water-borne, solvent-borne, high-solids and solvent-free resin systems
- Dense cross-linking enhances wet scrub resistance, chemical resistance and anti-corrosion properties
- Good storage stability and lower sensitivity to premature moisture hydrolysis than traditional silane monomers

Frequently Asked Questions
How does Manta OP200 lower VOC emissions compared with monomeric epoxy silanes?
As a pre-condensed oligomer it contains significantly fewer hydrolyzable alkoxy groups than monomers such as γ-glycidoxypropyltrimethoxysilane (Manta E560), so less alcohol is released during processing and curing. Hydrolytic stability in formulated systems is also improved.
Which formulation systems accept Manta OP200?
It is designed for water-borne, solvent-borne, high-solids and solvent-free resin systems, and it is used to modify epoxy, polyurethane and acrylic resins.
