A three-component moisture-curing polyurethane resin for PCB potting

The PJ6833-70 and PJ6833-70-2 are special modified aromatic aliphatic moisture-curing polyurethane resins developed by Jiangmen Resin.

PJ6833-70 and PJ6833-70-2 solvent-curing polyurethane resins are compatible with esters, ether esters, and ketones, and can be diluted with solvents such as dimethyl carbonate (DMC), n-propyl acetate, n-butyl acetate, propylene glycol monomethyl ether acetate (PMA), propylene glycol monomethyl ether propionate (PMP), dipropylene glycol monomethyl ether acetate (DPMA), and dipropylene glycol dimethyl ether (DMM). They can be limitedly dissolved in aliphatic solvents (D30, D40) before use. Customers are advised to test the suitability before use to determine the optimal application method.
