Environmental protection wood coating crosslinking agent
Environmental protection wood paint solution does not need to adjust spray line, also need not change original construction habit. High solid and low VOC wood coatings solution is based on polyurethane crosslinker Desmodur ? ILV170 and Uralac1801/2 resin development. Can effectively reduce VOC emissions by nearly 40% and meet the latest industry environmental standards (solvents below 420g/L). In addition, it also can improve the spraying efficiency, the realization of equal thickness can save 40% of the amount of coating, bring the furniture industry environmental protection coating solution.
Desmodur ? ILV170 patent product of solid content of about 70%, used in the existing formula and new formula of high solid resin can be greatly reduced VOC emissions, while maintaining the excellent product performance. Desmodur ? ILV170 is a patented product.
Laboratory tests, according to the results of Desmodur ? ILV170 presents high transparency, film forming ability, excellent number less, quick drying coating performance. The product is a new choice for the product development of coating customers, both from the appearance and the efficiency of production. The product can be used in the preparation of primer or surface paint, paint or varnish, high gloss or matte effect.
Another key element of high and low VOC coating solutions is resin products. 1801 and newly developed Uralac ? Uralac ? 1802 patent polymerization technology, using Desmodur ? ILV170, about 410 g/L can realize low VOC emissions. Different from traditional high solid content of resin, Uralac ? 1801 and Uralac ? 1802 curing speed, drying speed with the existing medium solid resin.
Uralac ? 1801 can be used to highlight effect, Uralac ? 1802 can create a matte finish. Another advantage of the product is that it is highly membranous. It can achieve the same film thickness as the existing coating system with less coating and improve the spraying efficiency.
Polyurethane wood coatings can be divided into closed primer, intermediate surfacer, paint, and special features special floor lacquer sealer permeability good, strong compatibility, in addition with polyurethane finish, two middle coat well, but also with lacquer, unsaturated polyester paint systems. Between two coat, on seal primer, face paint is a kind of intermediate coating, a further filling effect, make the wood paint has three kinds of specifications, its composition is slightly different, have different purposes and characteristics also vary.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Raw material ：
TDA industrial, Sichuan production
Ethylene (Et) polymer grade, Shanghai production
TEA industrial imports
A reagent grade additives
Unsaturated polyester wood coatings for solvent-free paint, mainly by the unsaturated bond dibasic acid and glycol polycondensation of unsaturated polyester as film former, in the role of the initiator, promoter or special energy, and used as a diluent containing unsaturated monomer polymerization of free radical crosslinking, form a mesh structure of insoluble film.
Varieties by crosslinking curing of the paint can be divided into three categories: type of unsaturated polyester paint, light and electron beam type of unsaturated polyester paint type unsaturated polyester paint. The paint does not contain volatile solvents, does not discharge poisonous and harmful gases, does not pollute the environment, once coating can obtain thick film. The film is composed of free radicals, and the normal temperature is dry, which is carried out outside of the inside of the paint film, and the thick film can solidify. The paint film is plump, hard and shiny.
Our country at present the development of waterborne wood paint type has the self-crosslinking, acid type, shape, pu water dispersion compared with solvent paint, water-based wood coatings in terms of energy conservation and environmental protection has incomparable superiority, not a lot of VOC emissions into the air, no organic solvent, water do thinner, save energy, but also exist shortcomings, waterborne wood coatings from traditional ideas, in the paint film performance, compared with the solvent wood coatings, dry slow, low hardness, easy to stick, paint film on the fullness than solvent wood coatings, based on the performance of waterborne wood paint are able to achieve, home decoration, hotels, restaurants and other public places, protection and decorative wooden door, panel, etc.
Domestic commonly known as wax coating, wood oil is vegetable oil is a kind of similar to paint and different from natural wood coatings, paint it and now that based on petrochemical production of synthetic resin paint, a completely different raw materials mainly refined linseed oil, palm wax, and other natural vegetable oil and vegetable wax and cooperate with other natural ingredients, even the color pigments are used in the food grade. So it contains no poisonous elements like triphenylbenzene, formaldehyde and heavy metals, which have no pungent scent, can replace paint for home decorating and outdoor garden wood.
