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
- Excellent adhesion to variety of metals, glass, concrete and inorganic substrates
- Excellent anti-corrosion properties
- Reduction of number layers in coating systems
- Improved water resistance
- 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)
