Low VOC coating used crosslinking agent
Latest wood paint innovation solution - high - solid, low VOC coating system. It brings a new choice and possibility for the realization of better sustainability of the furniture industry chain. The environmental protection type wood paint solution does not need to adjust the spray line, or change the original construction habits.
The solution of high - solid and low VOC wood coatings is based on polyurethane crosslinking agent and 1801/2 resin. Can effectively reduce VOC emission by nearly 40%, meet the latest industry environmental standards (solvents less than 420g/L). In addition, it can improve the spraying efficiency, achieve the same coating thickness can save 40% of the coating amount, bring environmental protection economic coating solution for the furniture industry.
The research and development of high - solid coatings has high professional requirements for crosslinking agent and resin products. It opens up new possibilities for product performance optimization, efficiency improvement and sustainable development.
The solid content of new products with excellent performance is about 70%, which can be applied to both existing formula and high solid resin new formula, which can greatly reduce the emission of VOC and maintain excellent product performance.
High transparency, good film forming, less coating, fast drying etc. Whether from the appearance or the production efficiency Angle, this product provides the new choice for the product development of the coating customers.
The product can be used in preparation of primer or finish paint, paint or varnish, high or matte effect.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Uses:
The product is identical to Ethancure 100 and Lonza DETDA 80, DETDA is very effective polyurethane elastomer chain extender; also be used as polyurethane and epoxy resin curing agent, epoxy resin of an antioxidant, industrial oils and lubricants . In addition, also as intermediates in organic synthesis.Especially for the RIM (reaction injection molding), is important in the field of spray polyurea chain extender species. Also can be used for casting polyurethane elastomer (CPU) and a curing agent, epoxy curing agent, epoxy resin of antioxidants, lubricants and industrial oils other antioxidants.
The curing speed of resin is fast and the drying speed is comparable with the existing medium solid resin. Can be used for high light effect, can build matte finish face. Another advantage is a high film. It can achieve the same film thickness as the existing coating system with less coating and improve the spraying efficiency.
Nakajima, etc will be sublimated Al (C2H7O2) 3 join the colloidal silica or alumina sol, such as glass substrate surface heat treatment, through material sublimation, surface roughness, the coating has a certain use chlorosilane or alkoxy silane process, coating the surface with super hydrophobic performance.
Nakajima and Yamaochi found that a small amount of TiO2 powder was added to superhydrophobic transparent coating, which could give the coating self-cleaning performance. To improve the mechanical strength of super hydrophobic transparent coating, Nakajima in sol-gel system, such as the phase separation phenomenon, using filling effect of colloidal SiO2 particles, preparation of the transparent hard super hydrophobic coating.
In the original RTV anti-fouling flash coating, the modified anti-icing coating has increased the anti-fouling performance and effectively improved the anti-icing effect. The process is simple and there is no need to carry out the circuit transformation, and has a broad application prospect. According to the pollution of the transmission line, the filler in the paint, polysiloxane and so on are adjusted.
Yang Yang on the basis of the original RTV pollution flashover dope on the hydrophobic material construct a micron nanometer double rough structure so as to realize the technical route of super hydrophobic, developed a super hydrophobic coating process, the preparation of insulator in this process of the preparation of super hydrophobic coating surface presents the "lotus effect". It can be used for the preparation of low surface coating system.
Benzene is a toxic solvent, which can cause the disease of hematopoietic system and cannot be used in coatings. In most countries of China and the world, there are strict limits on benzene content in the solvent. Ethylene glycol ether and its ester solvents (especially CAC) are highly toxic and should be banned. Some solvents are still necessary for coatings: toluene, xylene, mixed aromatic s-100, MIBK and diethylene glycol butyl ether. People are actively looking for new solvents not on the HAP list.
