Title: Polyurethane adhesives for reverse osmosis modules
Inventor: DEY TANMOY
IPC: C09J175/04
Filed: 2016-04-07
Granted: 2023-08-15
Abstract: An adhesive composition is made from a first part containing an isocyanate group-containing prepolymer that is a reaction product of a first isocyanate and at least one polyol; and a second isocyanate that is essentially unreacted with the first isocyanate, the at least one polyol, and the isocyanate group containing prepolymer; and a second part containing at least two polyols; wherein the adhesive composition is essentially free of diluent oils and solvents. A polyurethane adhesive is made by mixing the first part and the second part in a 1 : 1 to 1.2 : 1 weight ratio of the first part to the second part to form a mixture, and curing the mixture. The polyurethane adhesive can be used in articles, including semipermeable membranes and reverse osmosis modules. When a solvent is filtered through the semipermeable membranes by reverse osmosis, the polyurethane adhesive prevents or reduces osmotic blistering.
