No.ProductSystemSolid contentSolventCharacteristic & Application range
01SN-7061S/W70%Butanol / BCS / NBAEpoxy phosphate ester adhesion enhancer can significantly increase the adhesion of high-temperature paint and coil coatings to metal substrates, especially suitable for difficult adhesion substrates such as electroplating surface, non-ferrous metal, stainless steel, etc. Water and oil are universal, good compatibility, improve the salt spray resistance, water resistance and so on.
02SN-7088NS65-70%PMAIt can enhance the adhesion of paint film to metal and plastic substrate, and improve the flexibility of paint film. Thermoplastic acrylic and other resin systems with high glass transition temperature can be used as anti-silver agents for aluminum powder paint or pearl-like paint, with excellent anti-silver effect, and will not make metal pigments black. Suitable for all kinds of self-drying paint, such as single-component shell paint, plastic paint, etc., especially suitable for thermoplastic acrylic acid spicing CAB, NC and chloro-vinegar resin aluminum powder paint or pearl-like paint, for increasing adhesion and anti-silver effect.
03Phosphate ester
SN-7263
S/W58%BCSPhosphate ester adhesion enhancers can significantly increase the adhesion of high-temperature paint and coil coatings to metal substrates. Especially suitable for difficult adhesion substrate such as plating surface, non-ferrous metal, stainless steel, etc. Improve the salt spray resistance, water resistance and so on. Especially suitable for coil coating, high temperature baking paint, water paint and so on.
04Polyester type
SN-7227
S/W75%BCSEnhance the adhesion of the paint film to various metal substrates, and improve the water resistance, salt spray resistance, water resistance, and improve the flexibility and impact resistance of the paint film. Suitable for solvent-based, water-soluble and water-based acrylic amino paint, alkyd amino paint, polyester amino paint and other kinds of paint, especially suitable for coil paint, high temperature paint and so on. In the two-component polyurethane coating, single-component self-drying system also has a certain adhesion promotion effect.
05SN-7520S/W100%/Functional silane oligomer adhesion promoter, with excellent hydrolysis stability, can significantly increase the adhesion of coatings to metal, glass, ceramics and other substrates. Used for solvent-based or water-based systems to increase adhesion, corrosion resistance, while increasing the mechanical properties of the film, chemical resistance, etc. Used for water-based epoxy zinc-rich paint, it can also significantly increase the stability of zinc powder, improve the application period, and increase the salt spray resistance.
06SN-7560S/W100%/Epoxy modified silane coupling agent, improve adhesion to glass, metal, ceramics and other substrates, improve water resistance, alcohol resistance, chemical resistance. Suitable for polyurethane, epoxy (added in epoxy resin components), alkyd, amino paint and other systems, but also suitable for water-soluble and water-based coatings. (Must be added before construction, can not be directly added to the paint, so as to avoid hydrolysis failure)
07A300S70%IPAImproves adhesion on metal substrates in solvent-borne systems. Non-yellowing, good compatibility.
08A40S99%-Promotes adhesion on non-ferrous metals and low polarity plastics (such as PET, OPP etc.) in UV/thermo-cured coatings.
