Abstract
The invention features a spiral wound membrane filter including an outer shell, the outer shell including a reinforcement material and an acrylate adhesive composition including a multifunctional (meth)acrylate, wherein the adhesive composition has a viscosity of no greater than 10,000 cP when measured at 23° C. according to ASTM D1084 Test Method B.
Claims20
A spiral wound membrane filter comprising an outer shell, the outer shell comprising:
- a. a reinforcement material, and
- b. an acrylate adhesive composition comprising a multifunctional (meth) acrylate, wherein the acrylate adhesive composition has a viscosity of no greater than 10,000 cP when measured at 23° C. according to ASTM D1084 Test Method B.
A method of making the outer shell of a spiral wound membrane filter comprising the following steps:
- a. obtaining an acrylate adhesive composition comprising a multifunctional (meth)acrylate and an initiator having a viscosity of no greater than 10,000 cP when measured at 23° C. according to ASTM D1084 Test Method B,
- b. passing at least one continuous strand of reinforcement material through the acrylate adhesive composition,
- c. wrapping the continuous strand around the outside circumference, along the entire length of the spiral wound membrane filter, and
- d. exposing the continuous strand of reinforcement material coated with the acrylate adhesive composition to an energy source at a time selected from during wrapping, after wrapping and a combination thereof.
