2017-3-1 17:32:04
Coating with silane/ammonia ester mixed crosslinking agent, a series of high-performance wood coatings using new general crosslinking agent has been developed. VESTANAT? EP -m crosslinking agent of innovation is based on combining the advantages of silane chemical and the performance of polyurethane, both to increase the scratch resistance of the coating, while maintaining the performance of the ammonia ester. New method using 3 - isocyanate basis propyl silane three oxygen radicals (IPMS) as a key raw material, is good for free design and custom synthesis of basic material and crosslinking agent.
Adoption of isocyanate resin solutions (NIS) technology, shows that beyond the performance of polyurethane. The technology can be used in the monocomponent and bicomponent coating formula.
Two-component aliphatic polyurethane wood coatings technology is currently used for etching and durability of the benchmark environment, and is famous for its toughness and hardness of the perfect balance. The technology provides the first-class comprehensive performance, good wood substrate adhesion, and also can be used as primers and paint to sanding.
Multi-layer matte varnish. Varnish on the surface of the wood furniture is resistant to mechanical, physical and chemical effects of the first protective layer. Dust caused a minor, corrosive chemicals, such as detergent and sunscreen lotion, and cause swelling, colored objects such as red wine cause discoloration. Even after several years of varnish must also look as good as new.
Varnish quality is steadily improving, but still need to improve some performance, especially the resistance to wear. This trend is not limited to the market demand specific varnish.
Application of silane/ammonia ester mixed crosslinking agent, can enhance varnish scratch resistance, and meet the market demand for multi-functional varnish. IPMS can with all sorts of isocyanate reactive group (R group), especially the diol containing hydroxyl, multiple low alcohol and polyethylene glycol preparation an alkoxy silane reaction faculties of ammonia ester links of isocyanate (NISO) crosslinking agent or base.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine packingļ¼ 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).
R - group depends on the choice of main crosslinking agent, or the performance, thus significantly affect coating performance. Such as crosslinking agent, or the longer the skeleton, the greater the toughness in the coating effect. On the contrary, if R and the skeleton of short branched chain, the coating of the elastic.
With VESTANAT EP -m crosslinking agent formula, add ammonia ester chain, thus increasing the excellent properties of aliphatic polyurethane, such as chemical corrosion resistance, excellent adhesion and good mechanical properties.
IPMS kind of crosslinking agent, the use of the alkoxy can realize two possible reaction mechanism. To room temperature curing reaction may be through hydrolysis reaction and condensation reaction to form a siloxane bonding (Si - O - Si). Another crosslinking mechanism is the ester exchange reaction, reaction conditions is contain a hydroxyl (such as an acrylic polyol) and high temperature. As has been reported in the literature, apply the appropriate catalyst can accelerate any reaction mechanism.
This article describes a method of coating performance analysis of coating is by hydrolysis of the preparation of crosslinked at room temperature. In the first experiment, VESTANAT EP - MF 201 is the only base. In the second experiment, the hydroxyl acrylic resin used as curing agent, and formed an interpenetrating network, it is also a familiar epoxy siloxane technology.
To analyze the impact of siloxane network, and compared with standard of two-component polyurethane formula, the varnish formula as standard, to characterize VESTANAT EP - MF 201 is used as the performance of the unique makings. Room temperature curing time is about 1 hour.
VESTANAT EP - MF 201 is a solvent free, no cyanate ester, ready-to-use, alkoxy silane sealing side crosslinking agent or makings, don't need other crosslinking agent (e.g., polyisocyanate), can be applied to one-component moisture curing system. Use it to make the coatings shows excellent scratch resistance, stain resistance and chemical corrosion resistance.
