Sipomer® PAM series

Metal Adhesion

Adhesion and much more

Sipomer® PAM series are efficient specialty monomers added during emulsion polymerization to improve performance in adhesives and architectural and industrial coatings applications.

 

Sipomer® PAM series benefits

  1. Excellent adhesion to variety of metals, glass, concrete and inorganic substrates
  2. Excellent anti-corrosion properties
  3. Reduction of number layers in coating systems
  4. Improved water resistance
  5. Ability to shift from solvent borne to waterborne systems

 

Sipomer® PAM series key features

  • Effective in a wide range of polymer systems : All-acrylic, Styrene/
  • acrylic, VEOVA/Acrylic, Vinyl VEOVA, Polyurethane (Via acrylic polyols))
  • Effective in a wide variety of substrates (Aluminum (plain and chromated), Cold rolled steel, Zinc phosphated steel, Iron phosphated steel, Galvanized Steel, Stainless steel, Glass, concrete
  • Easy to incorporate
  • Small amount required (1%-4% BOTM)

Sipomer® PAM 200 was used to modify a waterborne styrene acrylic resin to improve anti-corrosion and adhesion properties:

 
Coating based on styrene acrylic latex with 1.0% Sipomer PAM 200
Coating based on styrene acrylic latex Control (Blank)
Adhesion is evaluated based on ASTM D3359 test
