Hema-P Products for Coatings & Adhesives
VISIOMER® HEMA-P is a polymerizable flame-retardant comprising a combination of a phosphoric acid and methacrylate moiety. The phosphate function is responsible for the flame-retardant properties.
The methacrylate group readily polymerizes and leads to a non-migrating agent.
A single-flame source test was conducted on acrylic polymer emulsions confirming the flame-retardant properties of VISIOMER® HEMA-P 70M containing emulsions.
It is particularly well suited for transparent applications, such as WB coatings for wood, paper and textile applications.
VISIOMER® HEMA-P is a well-known adhesion promoter in applications like adhesives or coating resins. As functional co-monomers, VISIOMER® HEMA-P products enable superior adhesion to polar surfaces like minerals, glass, and metals.
Corrosion protection, an important requirement for coatings, is a challenge to maintain in waterborne systems. Our studies on acrylic emulsions with 7 wt% of VISIOMER® HEMA-P 70M demonstrate enhanced corrosion resistance compared to resins without any anti-corrosion agent.
HEMA-P Products for Composites
FLAME RETARDANT PROPERTIES
VISIOMER® HEMA-P products can be used as co-reactive diluent in UPR or VE composite resins. Its phosphate moiety is responsible for its flame-retardant properties. Additionally, being a methacrylate monomer it is polymerizable and therefore a non-migrating flame retardant additive.
VISIOMER® HEMA-P products can be used to formulate non-halogenic and filler-free flame-retardant composite materials.
improved resin-glass fiber adhesion
As an adhesion promoter, VISIOMER® HEMA-P improves the adhesion of the composite matrix to
the glass fibers and results in an increased ILSS (Interlaminar Shear Strength). It helps to improve the strength-to-weight-ratio in glass-fiber reinforced composites.
