Press Release: VISIOMER® HEMA-P 100

Functional Monomers for Adhesion and Corrosion Protection in Coatings and Composites

VISIOMER® HEMA-P is a phosphate methacrylate designed to enhance performance across a wide range of applications. Its unique chemical structure enables strong adhesion, improved corrosion resistance, and compatibility with various resin systems. Below, you’ll find key application areas where VISIOMER® HEMA-P delivers measurable value in formulation and end-use performance.

Application Areas

VISIOMER® HEMA-P is a well-established adhesion promoter used in applications such as adhesives and coating resins. As a functional co-monomer, it enables strong adhesion to polar surfaces including minerals, glass, and metals.

VISIOMER® HEMA-P is a polymerizable flame retardant combining a phosphoric acid group with a methacrylate functionality. The phosphate moiety imparts flame-retardant properties, while the methacrylate group enables polymerization, resulting in a non-migrating additive. Flame performance was confirmed through single-flame source testing on acrylic polymer emulsions containing VISIOMER® HEMA-P 70M. The product is particularly suitable for transparent applications such as waterborne coatings for wood, paper, and textiles.

VISIOMER® HEMA-P products can be used as co-reactive diluents in unsaturated polyester (UPR) and vinyl ester (VE) composite resins. The phosphate group contributes to inherent flame-retardant properties. As a polymerizable methacrylate monomer, VISIOMER® HEMA-P acts as a non-migrating flame retardant additive. It enables the formulation of halogen-free, filler-free flame-retardant composite materials.

Corrosion protection is a critical performance requirement for coatings, especially in waterborne systems where maintaining long-term resistance is challenging. Studies on acrylic emulsions containing 7 wt% VISIOMER® HEMA-P 70M show improved corrosion resistance compared to formulations without dedicated anti-corrosion additives.

As an adhesion promoter, VISIOMER® HEMA-P enhances the bonding between the composite matrix and glass fibers, resulting in increased interlaminar shear strength (ILSS). This contributes to improved mechanical performance and supports a favorable strength-to-weight ratio in glass fiber-reinforced composites.
