2021 Good Quality Polyester Fiber - Manufacturer Good Price EPOXY RESIN CURING AGENT PACM CAS#1761-71-3 – INCHEE Detail:
Applications of PACM
EPOXY RESIN CURING AGENT PACM can be used to process various types of environmentally friendly polyurethane coatings and adhesives with good transparency and yellowing resistance. The epoxy resin cured by EPOXY RESIN CURING AGENT PACM has Chemicalbook’s excellent heat resistance, dielectric properties, solvent resistance, mechanical properties, as well as excellent optical properties, weather resistance, and can be used in damping materials, optical materials, coatings, Engineering plastics, adhesives and other fields.
- 4,4′-Methylenebis(cyclohexylamine) is a potential high inhibitive and high temperature resistant shale inhibitor.
- 4,4′-Diaminodicyclohexyl methane be used as organic intermediates and epoxy curing agents.
- 4,4′-Diaminodicyclohexylmethane is used as epoxy curing agents. It is a versatile intermediate to produce leather, rubber products, plastics, dyes, and photo sensitive polymers. It is used in manufacturing diisocyanates and polyamides. It is also used as lubricant additive as and corrosion inhibitor.
Preparation: Diversify 1g titanium dioxide powder in 40ml of water and methanol mixture (water to a methanol volume ratio of 9: 1), stir well after mixing evenly, add 60 μmol/ml RUCL3 · XH2O dark brown aqueous solution to control the amount of titanium dioxide in titanium dioxide The load is 5WT %. After 3 hours of sealing the room temperature seal and stirring for 3 hours, add 1m sodium hydroxide solution until PH10.5 continues to seal and stir for 20 hours. After the centrifugation and water and ethanol mixture was washed with water and ethanol for 3-5 times, 60 ° C. catalyst. Fresh prepared catalysts are placed in the reactor, a certain volume of solvents are added, and an appropriate amount of 4,4’- two Chemicalbook amin aminomyl methane (MDA) is added. After 10 times, the closed reactor was rinsed with a hydrogen reaction kettle to 150 ° C to start the reaction. The Moore ratio of the hydrogen and MDA was not less than 80, and the hydrogen pressure was 1 to 5MPa, and the reaction product and conversion rate were taken in real time. The benzene ring in MDA can be quickly hydrogen to generate a single benzene ring hydrogenation product (+6H) and the hydrogenation of hydrogenation of bisopyzhenbenzhenyl. It is worth mentioning that the 4,4′-dihydrophill methal methane is a raw compound of a special nylon.
