QM-7560 Adhesion Promoter

Product Overview:

QM-7560 is an epoxy stannin coupling agent suitable for use in epoxy (added to epoxy resin systems), polyurethane, and amino baking varnish systems to improve the adhesion of coatings to glass, metals, and ceramics. QM-7560 is amine-free and will not yellow during storage. When using SN-7560 in water-based coatings, it must be added before application and cannot be added directly to the coating. When used in solvent-based coatings, attention should be paid to the water content of the solvent; high water content may affect storage stability.

Physicochemical Parameters:

Composition: γ-glycidyl etheroxypropyltrimethoxysilane

Appearance: Colorless transparent liquid

Active content: >99%

Boiling point: 290°C

Solubility: Soluble in water, undergoing hydrolysis to release methanol. Soluble in alcohols, propane, and some aliphatic hydrocarbons.

Product Characteristics:

As an inorganic surface treatment agent, it can activate glass wool, silica, talc, mica, kaolin, and pyroclastic.

In coating systems, it can increase adhesion to glass, ceramics, and metals.

It can participate in the cross-linking of paint films, thereby increasing the mechanical properties of the paint film.

Containing epoxy groups, it cannot be added to polyamide systems.

Application Systems:

It can be used in polyurethane, chloroform, alkyd, and amino baking paint systems, and is also suitable for water-soluble and water-based coatings (it must be added before application and cannot be added directly to the coating to avoid hydrolysis and failure).

Recommended Dosage: 

The recommended dosage is approximately 0.3% to 3.0%, and it can be added at any stage of production. When adding it to the coating, attention should be paid to the solvent’s moisture content, as high moisture content may affect storage stability. Before coating, all grease and liquid moisture on the substrate must be thoroughly cleaned.

Packaging and Storage:

25kg/drum or 200kg/drum.

The product should be stored in a cool, ventilated place. Unopened, the shelf life is 12 months from the date of production.
