Water-based polyurethane soft coating crosslinking agent
In recent years, the automobile industry has been looking for soft, high quality and comfortable surface. In the for mobile devices, the consumer electronics industry (more for hand-held electronic equipment) design is more comfortable grip coating, and has good resistance performance, even fingerprint resistant fouling resistance and other properties.
On the other hand, the development of water-based coatings is important because of strict environmental regulations and the continued cry of VOC. In order to realize these characteristics, we can use environmentally friendly water-based polyurethane coating to be a sustainable coating system. The latest generation of the coating system also meets the strictest specifications for hydrolysis, resistance to yellow and chemicals. The process currently under development can make the production of soft coatings more effective and have wider range of changes.
Waterborne two-component polyurethane soft feeling coating system not only can make the instrument panel, instrument panel, door handles, door gasket, armrest and glove box baffle more aesthetically pleasing, it can also be an initiation touch. This is a simple and ideal way to improve the quality of plastic and metal parts. This is especially true of the new generation of soft senses.
Softness waterborne polyurethane coating no matter from the physical and chemical protection of substrate, or in terms of aesthetics, can provide superior performance, but also combines the luxurious tactility. Therefore, in recent years in the coating market, water water polyurethane soft feeling coating has gotten more and more extensive attention.
Generally, unprocessed cheap plastic, not only ugly appearance, feel is rough, and when a few parts of friction, emits an aggravating squeak, further realize the defect of product quality. But when these plastic parts are coated with soft paint, not only does the friction fade away, but the rough, ugly surfaces are aesthetically pleasing and tactile.
Chinese name: Diethyl toluene diamine(DETDA)
Physical and chemical properties: light yellow transparent liquid, slightly soluble in water, soluble in alcohols, ethers, ketones and other polar organic solvents, and polyether, polyester polyol compatibility.
Density 1.022
Viscosity (20 ℃) ??mPa·ss290±10
Pour Point ℃-9
Boiling point of310°C
Flash Point°C161.1°C
With a luxurious touch products can make person sense gentle, soft, like leather, a simple layer of coating can make product from rough cheap to luxury. Flexible coating not only can be used in plastic products, but also can be used in metal products, rubber soles, PVC, composite materials, etc. Softness coating can be used as car interior paint, including automotive instrument desk, door handles, door frame, etc., also can be used as car interior coatings to improve the quality of decoration of the car.
In addition, the softness of coating in the consumer electronics industry has also been widely used, various electronic products, office equipment, household appliances, especially in digital products, mobile phones, laptops, MP3 players, etc., product of touch and feel is largely one of the important parameters of consumers to make choices.
The principle of water-based bicomponent polyurethane coating. With the upgrading of technology, polyurethane soft feeling coating system can adopt different technical system to achieve: the traditional solvent-based and waterborne two-component polyurethane and two-component polyurethane UV light curing polyurethane and so on. The traditional solute two-component polyurethane is still dominant in the soft coating market, which is the mature technology system in the market.
The formulation principle also usually use polyester branched high degree of uniformity and linear polyester polyol collocation points (part A), as the resin aliphatic polyisocyanate curing agent as the crosslinking agent (part B), adjusting the proportion of different to realize the different feel and performance.
The commonly used resin polyols on the market, such as Desmophen 670, 1652 and Desmophen Desmophen C1100 or C1200 and so on, with use of curing agent, has Desmodur N75, Desmodur N3390, or soft type curing agent Desmodur N3800, or high-performance firming agent N3790, XP2679 to enhance RCA or contamination resistance.
