QM-7063 Adhesion Promoter

Product Overview:

QM-7063 is an adhesion promoter developed based on phosphate ester technology, possessing multiple anchoring groups. It exhibits extremely strong adhesion to metal substrates and contains epoxy and hydroxyl groups, allowing it to participate in the cross-linking reaction of resin systems. It is particularly suitable for coil coatings, as well as other baking varnishes, water-based coatings, and other pure water-based baking varnish systems. It also increases adhesion in other two-component and one-component coating systems, but testing is required.

Product Characteristics:

Improves paint film adhesion to various hard-to-adhere metals such as aluminum, zinc, stainless steel, and electroplated surfaces;

Increases the ductility and impact resistance of the paint film;

Does not discolor during high-temperature baking, suitable for high-temperature baking paints and coil coatings.

Application Systems:

Suitable for various coating and ink systems, such as industrial coatings, printing can and coil coatings, anti-corrosion coatings, acid-curing primers, etc.

Recommended Dosage: 

0.5%~5%, or 5% or even higher for substrates that are particularly difficult to adhere to. It can be added at any stage of production.

Packaging and Storage:

25kg/drum or 200kg/drum.
