HEMA
HEMA contains hydroxyl groups, capable of crosslinking with isocyanates and melamine formaldehyde resins, offering excellent adhesion. It has good wetting properties on plastic, metal, and glass substrates and is highly water-soluble. It can enhance system wettability and pigment dispersion.
Product Description
Main Uses
Primarily used for modifying resins and coatings. Copolymerizing with other acrylic monomers can produce acrylic resins with active hydroxyl side chains, enabling esterification and crosslinking reactions to synthesize insoluble resins and improve adhesion, usable as fiber treatment agents.
Reacts with melamine-formaldehyde (or urea-formaldehyde) resins, epoxy resins, etc., to make two-component coatings. When added to premium automotive paints, it can maintain a mirror gloss for a long time. It can also be used as an adhesive for synthetic textiles and as a monomer for medical polymers.
Used as a crosslinking monomer in solvent-based or emulsion-based acrylate adhesives. Due to the presence of polymerizable vinyl bonds and active hydroxyl groups, it easily homopolymerizes to form soft resins with excellent gloss, transparency, and weather resistance, used as contact lens materials.
Also used in producing photosensitive resins, medical polymer materials, and thermosetting coatings. Reacting with melamine formaldehyde resins and epoxy resins can produce two-component coatings for premium automobiles. It can also be used as a modifier for resins used in fiber and non-woven fabric processing, and paper processing resins.
