1. At present, the most widely seen and used sealant in China is Huitian 586,588 of Hubei Huitian Company. Huitian Company was formerly a scientific research institute under the National Spark Plan, and was later restructured by state-owned enterprises. At present, Huitian Company has two wholly-owned branches in Guangzhou and Shanghai.
huitian company is the earliest company engaged in the adhesive industry in China. Its early products were mainly supplied to national defense and military industry. Later, after restructuring, it launched the first domestic polymer sealant LG-31, and then developed the first domestic 586 black sealant and 588 red sealant.
Huitianjiao has good quality, and has successively obtained ISO91 international quality certification, ISO/TS16949:22 automobile production parts and service parts quality management system certification, National Spark Plan certificate, People's Daily's China adhesive market product quality customer satisfaction first brand, China professional adhesive supplier, and the honorary title of China famous trademark. Its products have more than 4 varieties and specifications in 8 series, which are widely used in aerospace, military, automobile, machinery, metallurgy, electronics, construction and other industries. At present, Huitianjiao has achieved matching with Steyr, Shaanxi Automobile, Dongfeng, FAW, Heavy Duty Truck, Yuchai, Shandong Lingong and other manufacturers.
586 was introduced by Huitian Company after LG-31 in 1986. It is the first gasket-free adhesive in China. Its characteristics are: temperature resistance of -6 degrees to+28 degrees, pressure resistance of 1MPa, and it can replace all kinds of gaskets to seal flanges, covers and pipe joints. 588 is the first domestic red sealant introduced by Huitian Company in 1988. Compared with 586, its temperature resistance has been greatly improved, and the highest temperature resistance can reach +32 degrees. For some engines, valve chambers, exhaust pipes and other parts with high temperature requirements, seal them.
the difference between 586 and 588 is that 586 is characterized by good oil resistance and will not be corroded after being soaked in oil for one year. The biggest feature of 588 is its good temperature resistance, and the highest temperature resistance can reach +32 degrees.
because numbers are not allowed to register trademarks, the market is full of 586,588 times. Back to Heaven 586 was renamed Jiuwang (formerly Back to Heaven 586), and Back to Heaven Red Devil 588 was renamed Weifeng. Later, an "instant seal" made of gray nano-materials suitable for quick repair was introduced.
At present, the best sealant in the domestic market is "Huitian" glue, followed by Guangdong "Sanhe" glue. Shanghai Jiayuan glue was originally a branch of Huitian glue, but it was separated later, and the quality was acceptable. The worst quality is Wuxi glue, followed by Guangdong glue (except Sanhe) and Hebei glue.
2. Imported American camel's 588 red sealant is good, but at present, most of the domestic products are fake camel glue produced in Guangdong, and the real products are rarely seen in the market.
3. The special gray glue for Toyota in the car market is also good, but it is very expensive, more than 2 yuan each, and it is special for 4S shops, so it is not easy to buy it outside. The quality of glue in Yantai Le Tai is good, especially in some buses such as Steyr and Ou Man, which are used in planar sealant 51 and 515.
