Powder coating with crosslinking agent

Powder coating with crosslinking agent,Three different cyanuric acid - beta - methyl glycidyl ester [tri - beta methylglycidylisocyanurate

Because of its containing methyl, compared with those of TGIC is influenced by space steric hindrance its reactivity fall greatly, therefore need to join in the preparation process of powder coating catalyst, which affect the storage stability. But it is the closest TGIC crosslinking agent, according to the manufacturers claim that their toxicity than TGIC is low, no toxic labels.

Several years ago, methyl glycidyl ester of acrylic (GMA) Estron (USA) and Worlee (Europe) will provide the commodity name for GMA300! Methyl glycidyl ester of acrylic polymer. Mainly refers to by the following monomer GMA resin as the main functional units.

This is TGIC appropriate substitute. Compared with AralditePT910, does not need to be specially designed polyester, can be used for the design of the conventional polyester TGIC, acid value is the most suitable for 22-26 mgkoh/g polyester.

Senior officials to degrees of GMA resin has far more quickly than the TGIC crosslinking speed, reaction will lead to the rapid rise of viscosity and flow on the surface of the square problem; In addition GMA resin easy phase separation with the formula of polyester resin, the compatibility is bad, lead to pigment wetting performance deterioration of the coating is used flowers; If you can't effectively improve dispersion of its mechanical properties is poor. In some conditions the system can produce pollution and the existing coating systems.

GMA300 compared with those of TGIC system of epoxy equivalent of about 300, such a high dosage of GMA hybrid powder coating resin as cross-linking agent, general is 16/84 weight portions, and therefore is not economic. Using GMA300 as crosslinking agent of coatings in the field of outdoor durability and fairly TGlC powder. But the coating hardness is lower than TGIC system.

Nylon powder coating. Nylon (Nylon), also known as polyamide, due to the molecular chain of chlorine based on N atoms and hydrogen atoms on the adjacent segment is easy to form hydrogen bonds, so the melting point of polyamide resins are generally higher.

Nylon has high mechanical strength, shock resistance, hardness, wear resistance and low friction coefficient, low dust collection etc, and can be used in the special requirements of parts. As used in the pump impeller, textile machinery parts and components, the starting of diesel engine piston, auto parts, motorized boats propeller impeller wheel, motorcycle, agricultural machinery, construction and sports equipment, etc.




Chinese name: Diethyl toluene diamine(DETDA)

Diethyltoluenediamine packing： net weight 200KG/ galvanized iron drum (a small cabinet pallet loaded 16 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).


In addition, due to the salt water resistance of nylon and inertia of mold, bacteria, very suitable for seawater or access to the coating of the water, at the same time, non-toxic, tasteless, nylon powder coating were not mould erosion, will not prompt bacteria growth, very suitable for spraying the parts of the food industry, drinking water and food packaging, etc.

Fluorine resin powder coatings. Fluoropolymer were many, many different kinds of powder coatings, such as teflon (PTFE), polytrifluorochloroethylene (PTFCE), poly (vinylidene fluoride) (PVDF), etc.

Ptfe melting point 327 ℃, can use for a long time within the range - 250 ~ 250 ℃, moreover also has excellent corrosion resistance, even also not corrosion in aqua regia, excellent dielectric properties, low coefficient of friction and self lubrication, so known as "plastics king".

Widely used in petroleum, chemical anti-corrosion coating, seal, bearing lubrication materials, electronic materials, launching guideway and titanium coating, etc. Polytrifluorochloroethylene PTFE price is cheap, can reduce the processing temperature, coating can be used under 130 ℃ for a long time, alkali resistance and hydrogen corrosion resistant ability is better than that of acid resistant enamel, hydrochloric acid, thin sulfuric acid, hydrochloric acid and chlorine corrosion resistant ability is better than that of stainless steel equipment.

Has a large number of applications in chemical, pesticide plant, pharmaceutical factory, detergent factory of anticorrosive equipment, etc. A major advantage of poly (vinylidene fluoride powder coating is excellent weatherability, had high resistance to degradation in outdoor exposure, and does not absorb dust, easy to maintain the original luster.
