Coating classification: epoxy silane crosslinker

Core tip: Introduction: the epoxy silane crosslinker, xr500, is mainly applicable to the aqueous system containing carboxyl and amino groups The reaction mechanism is that the epoxy group in the crosslinker reacts with the hydrophilic group, carboxyl and amino groups of the aqueous resin; the alkoxy group reacts with water for hydrolysis condensation to form the silica bond, thus greatly improving the adhesion and water resistance of the coating film to the substrate Epoxy silane crosslinking agent (xr500) is a new type of environmental friendly and non-toxic coating additive It is particularly amazing that the application period of the water-based system with epoxy silane cross-linking agent xr-500 is abnormally long, which can reach one year at room temperature Therefore Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Coating home news: Introduction: the epoxy silane crosslinker, xr500, is mainly used in water-based systems containing carboxyl and amino groups The reaction mechanism is that the epoxy group in the crosslinker reacts with the hydrophilic group, carboxyl and amino groups of the water-based resin; the alkoxy group reacts with the water through hydrolysis condensation to form the silica bond, so as to greatly improve the adhesion and water resistance of the coating film to the substrate Epoxy silane crosslinking agent (xr500) is a new type of environmental friendly and non-toxic coating additive It is particularly amazing that the water-based system with epoxy silane crosslinker (xr500) has an abnormally long application period, which can reach one year at room temperature, so it can be prepared into a stable one-component coating Features: technical index type of the project: colorless and transparent liquid specific gravity 1 molecular weight 288.46 refractive index 1.45 flash point / ℃ 104 boiling point / ℃ > 300 active ingredient /% 100 recommended formula: ① the recommended addition amount of epoxy silane crosslinker xr-500 in metal coating is 1% of the solid content; ② It is suggested to add 2% of the solid content in leather coating, 2% of the solid content in plastic coating and 1.5% of the solid content in glass coating; ⑤ It is suggested to add 0.5% - 1.2% of the solid content of epoxy silane crosslinker in architectural coatings; ⑥ it is suggested to add 2% of the solid content in general waterborne wood coatings, 3% for floor coatings, 1% for textile coatings, and 3% for special washing water requirements It is suggested to use: ① the two-component can be directly added to the water-based system to replace isocyanate, aziridine and amine crosslinking agent; ② the pH value of the water-based system should be adjusted to 6-8 when the single component is used, which is conducive to long-term preservation; ③ the general addition amount of epoxy silane crosslinking agent xr-500 is 0.5% - 3% of the solid content of the resin, which can be appropriately added in special requirements; ④ When the epoxy silane crosslinking agent (xr500) is used, if it is difficult to disperse and dissolve, some non-ionic emulsifiers can be used for emulsification before adding Note: the epoxy silane crosslinker, xr-500, belongs to the environmental friendly and non-toxic crosslinker, which can be used at ease Once it contacts with the skin, it can be washed directly with soapy water or clear water Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
