Chartwell B-505.1 Mercapto functional organic Chartwell International Adhesion Promoters Epoxy (EP) PU - Prepolymers ADHESIVE A mercapto functional organic adhesion promoter synthesized using a STABILIZED BIMETAL PRECURSOR. The product is supplied in ethylene glycol to aid in rapid dispersion and solubilization of the active component in polymer matrices. Recommended for epoxy (esp. dicyanamide cured) and urethane adhesives to enhance adhesion to metals, plastics, and elastomers. Increased T-peel strength. Improved resistance to moisture, heat, and corrosive environments. Mercapto functional organic adhesion promoter synthesized using a stabilized bimetal precursor. Used in epoxy and urethane adhesives. Enhances adhesion to metals, plastics, and elastomers. Increases T-peel strength. Improves resistance to moisture, heat and corrosive environments.
