M505 & M506 is a functional water-based adhesive additive which is used to enhance the adhesion of most common emulsion such as waterborne epoxy, waterborne acrylic acid and waterborne polyurethane and substrates (including metal, glass, ceramics, concrete and other inorganic substrates).
The molecule of M506 has strong activity which is able to form strong covalent bond with emulsion and inorganic substrate, which makes the binder and substrate have strong adhesion and be difficult to peel off.
