APPLICATIONS :
Gujmet is often copolymerised with other monomers to improve and provide
specific properties in the product. Presence of Acid groups of Gujmet in a
copolymer increases the hardness, raises the softening temperature improves
oil and corrosion resistance and adhesion property. Also it improves
freeze / thaw stability of emulsion. Free acid groups are also used for
cross linking with epoxy resins and multivalent metal ions to produce
thermo-setting finishes.
Gujmet can be polymerised / copolymerised to produce polyelectrolytes.
Polymer/copolymer produced from Gujmet is neutralized with Alkali metal
or Ammonia to manufacture water soluble polymer salts. These salts are
widely used as viscosity modifier / thickening agents in paints. Some
alkali metal salts are used as dispersing agents.
Copolymers, esters, cross linking agents and water soluble polymer
salts of Gujmet are used in various fields depending upon their functional
applications.
