Coating by using coupling agent function sex. Due to the development of new structure and excellent performance of epoxy resin progress is not big, to meet the requirements for resin, and the crosslinking agent with special functions will become a market darling.
Compared with the traditional crosslinking agent, coupling agent function sex usually has a quick crosslinking, low temperature crosslinking, toughening, flame retardant, such as the excellent performance.
With the development of new crosslinking technology, powder coating crosslinking agent also in development. Should further looking for crosslinking temperature is lower, crosslinking, add more fully heat smaller, more energy saving material, and the coating in good condition, good flexibility, good resistance to hydrolysis and low moisture absorption material, or low viscosity, high permeability, excellent storage stability and good applicability, crosslinking agent for powder coating.
Certain, thermosetting resin adhesives such as epoxy resin, phenolic resin, and crosslinked unsaturated polyester resin adhesives after low extension, and large brittleness, when bonding parts under external force is easy to produce cracks, and rapidly expand, result in the crack of the rubber, not fatigue resistance, not for the use of structural adhesive. Therefore, must try to reduce the brittleness, increasing toughness, improve the bearing strength. Whoever can reduce the brittleness, increase the toughness, and shall not affect the other main performance of the adhesive material is toughening agent. Can be divided into rubber toughening agent and thermoplastic elastomer toughening agent.
Toughening means can increase the adhesive coating layer of flexible material. Certain, thermosetting resin adhesives such as epoxy resin, phenolic resin, and crosslinked unsaturated polyester resin adhesives after low extension, and large brittleness, when bonding parts under external force is easy to produce cracks, and rapidly expand, result in the crack of the rubber, not fatigue resistance, not for the use of structural adhesive. Therefore, must try to reduce the brittleness, increasing toughness, improve the bearing strength. Whoever can reduce the brittleness, increase the toughness, and shall not affect the other main performance of the adhesive material known as toughening agent.
Toughening agent generally contain active group, can react with resin, crosslinking is not fully compatible, after sometimes split phase, get ideal toughening effect, thermal deformation temperature is constant or dropped, with little, and shock resistance improved significantly. Some low molecular liquid or as plasticizer join resin, although also can reduce the brittleness, but rigidity, strength, heat distortion temperature dropped substantially, can not meet the requirement of the structural adhesive, therefore, plasticizer and toughening agent is completely different.

The main components of the paint includes the following five most:
(1) oil, including drying oil and semidrying oil, is one of the main film forming material.
(2) resin, including natural resin and synthetic resin, is part of the main film forming material.
(3) paint: including pigments, extender pigment and antirust pigment, breed is various, specific for secondary film-forming substances.
(4) thinners: including solvent and diluent, used to dissolve the above material and dispensing consistency, for auxiliary film-forming material.
(5) accessories: including drier, crosslinking agent, plasticizer, moistureproof agent. Also belong to auxiliary film-forming material.
Decorative coating composition: the main film-forming material, also known as adhesive and fixing agent, is the basis of the composition of coating.
Secondary film-forming material, and constitute a part of the film, but it can't leave the main film forming material and separate the coating.
Auxiliary film-forming material: including solvent and auxiliary materials. The former such as gasoline, oil smoke, rosin water, benzene, ethyl acetate, acetone, etc.; The latter such as crosslinking agent, emulsifier, tackifier, agent, wetting agent, dispersing agent, defoaming agent, initiator, catalyst, stabilizers, anti-ageing agent, antifreeze, etc.
Paint according to the reaction and the process is divided into PE, PU, UV, NC four classes.
