Environmental protection coating of crosslinking agent
2017-4-8 11:48:07
Environmental protection coating of crosslinking agent, the scientific research personnel development environmental protection coating no stimulation to the skin. Using polyester/TGIC powder with polyester/Primid powder solution, namely Primid/TGIC double crosslinking system.
In recognize the benefits of Primid&TGIC both at the same time, and avoid the disadvantages of Primid&TGIC, find a balance. And control the quantity of ultrafine powder particle size, the median diameter control in 37 about um, 3 um the following basic no fine powder. Prevent the powder float in the sky.
Through customer continuous use, the operator not stimulate the skin and eyes. Primid/TGIC double crosslinking reduce the amount of heat TGIC powder, to eliminate the influence of human allergic. Also no Primid system film defects such as coating the surface of the fog.
Primid/TGIC double crosslinking scheme, although solving the influence of operators is allergic to the skin and eye irritation, but the existence of TGIC still does not conform to the requirements of REACH. So, using Primid/PT912 double crosslinking solution to the best of both worlds.
PT912 low melting point, lower Tg was stronger than TGIC, will more effectively promote a smooth surface. Formula can be added in the methods of antioxidant and yellow rest, improve the resistance to yellow degeneration. Can also be added in the formula of zinc salt, etc. To improve corrosion resistance to salt fog.
Primid/PT912 double white powder (luminous intensity crosslinking system: 550 + 20 w/m2 "290 ~ 800 nm"; the blackboard 65 + 5 ℃ temperature; wet medium 18 min, drying medium 102 min cycle 1000 h)
Primid/PT912 double crosslinking system environmental powder low toxicity, integrated the advantages of polyester/TGIC and polyester/Primid as much as possible to avoid the disadvantages of the two. Is the optimal environmental powder ratio of products on the market.
PT912 terephthalic acid 60% 40% glycidyl ester and trimellitic formate three glycidyl ester mixture. Believe that products suitable for the market will continue to innovation and optimization. The pursuit of environmental protection is our goal and end-result.
Market economic model is the survival of the fittest, can be seen from the advantages and disadvantages of several kinds of green powder, double crosslinking system is the most advantage of green powder varieties. Through the joint development and polyester manufacturer, suitable for double crosslinking polyester products already has too many companies.
Chinese name: Diethyl toluene diamine(DETDA)
Chinese alias: aryl, aryl diethyl - aryl - methyl-p-phenylenediamine

Hazard Class: 6.1
Most manufacturers in selecting active solvent usually turn around the "youngest sample" : when it comes to alcohol usually choose/isobutanol, isopropyl alcohol. When it comes to ketones are run not to drop, butanone, acetone. Consider preferred butyl ester, ethyl ester. There are a lot of good performance of solvent suggested considering: such as alcohols of propyl alcohol; To methyl ketone ketone (2 - g) used in the nitrocellulose coating can effectively improve the coating film ductility, moisture resistance and gloss.
Three methyl ketone in the coating can be used as a gas flow ping agent of dry and drying system, can reduce the bubbles and the formation of shrinkage cavity, improve liquidity and luster.
At present most of the polyester resin as base material flow of coil coatings manufacturers to improve the coating property, will join with high boiling point, low hygroscopicity, slower rate of relative volatility (0. 02) and highlight the dissolving capacity of different fluorine ketone; And isobutyl ketone (DIBK) used in polyester resin as base material of coil coatings and canned coating can effectively improve the coating in the coating performance.
High carbon alcohol acetate can obtain higher resistivity of coating, because of the influence of resistivity of coating of the atomization characteristics and the transfer efficiency of electrostatic spraying, so want to electrostatic spraying coating resistivity to 0. 6-1. 0 m euro, but this for metallic coatings, etc. It is a difficult problem, and with close to hydrocarbon solvent resistivity high carbon alcohol acetate solvent not only can obtain high resistivity, can be obtained at the same time provides the dissolving capacity of hydrocarbon solvent.
As one of the high carbon alcohol acetate, ethyl acetate, and alcohol ether acetate compared with high boiling point ketone solvents, use it for is sensitive to the moisture of the various kinds of gas dry coating, not only because of its volatile rate slower and effectively reduce the film "white", at the same time because its escape from the film diffusion speed is faster than the former, it can be obtained at the same time, fast drying speed: under the condition of normal temperature: ethyl acetate than glycol ether acetate esters fast drying speed of 15% - 15%, this feature in the nitrocellulose coatings, two-component polyurethane coatings and volatile type of acrylic resin coating application shows unique advantages.
