Organic metal ester coupling agents (titanium esters, zirconium esters, and aluminum esters) are a type of coupling agent (bridging agent) that have both inorganic reactive groups and organic reactive groups in the same compound molecular structure, with a 4-valent (titanium, zirconium) or 3-valent (aluminum) metal as the central atom. Although they have four reactive groups attached to the same molecular structure as silane coupling agents (except for aluminum esters...

Silane coupling agent SCA and titanium (zirconate, aluminate) coupling agent TCA are widely used in industries such as plastics, rubber, coatings, and adhesives, playing multiple roles in improving the dispersion of pigments and fillers, enhancing product strength, and improving the adhesion of resin coatings to substrates. They play an indispensable and important role in many product formulations.

The protection of the coated object by the coating is largely influenced by the bonding strength between the coating and the substrate, and the size of the bonding strength is not only related to the surface state, surface material composition, and material density of the substrate, but also to factors such as the shrinkage stress, surface tension, crystallinity, and volume size of polar functional groups of the film-forming material in the coating. The paint film and substrate ...

Thermosetting powder coatings do not contain any organic solvents and do not release VOCs into the atmosphere. They have the advantages of being harmless, efficient, resource-saving, and environmentally friendly. Thermosetting powder coatings are generally composed of thermosetting resins, curing agents, pigments, fillers, and additives. Common thermosetting powder coatings include:

CapatueTM plastic foam carrier is a type of highly foamed polymer particle used as a carrier (adsorbent). Currently, there are four types of resin products that can be commercially produced: LLDPE, LDPE, HDPE, and EVA. CapatueTM plastic foam carrier provides ...
