Adhesion and much more...

Sipomers are efficient specialty monomers added during emulsion polymerization to improve performance in adhesives and architectural and industrial coatings applications.

 

Benefits

  • Excellent adhesion to variety of metals, glass, concrete and inorganic substrates
  • Excellent anti-corrosion properties
  • Improved water resistance
  • Ability to shift from solvent borne to waterborne systems
