Uses: mainly used as hardening accelerator for epoxy resin, crosslinking agent for phenol, silicone, acrylic resin. In white ink, transparent ink and other inks, the adhesion is obviously improved, and the color will not be darkened. Aluminium acetylacetonate and the substrate, ink, and paint conjugates form phenolic antioxidants and form a chelating effect to improve the adhesion of electronic adhesives in use.
Usage: If the substrate does not contain -OH, -COOH, -NH2, etc., it must be pretreated. Resins such as PA, NC, PU, PVB, CAB, CAP, EVA, etc. can be used directly.
Recommended dosage: The amount of bridging agent for acrylic pressure-sensitive adhesive (solvent type) is about one thousandth. The specific dosage adjustment in summer/winter depends on the effect.
