LED light curing reduces work in process

LOCTITE® 3921™ Light Cure Acrylic Adhesive Offers Faster Processing for Spiral Wound Filters

Henkel has introduced a new method for protecting the membrane folds in spiral wound filtration elements: LOCTITE® 3921™ light cure acrylic adhesive, which offers improved fold protection with faster processing.

LOCTITE 3921 dispenses and cures in less than 10 seconds, offering a significant advantage for spiral wound membrane producers. It reduces expensive work in process and messy, wasteful two-component polyurethane systems. Alternate methods of fold protection, such as thermoplastic tapes or two-component polyurethanes, have process and performance limitations. LOCTITE 3921 light cure acrylic provides both faster speed and high performance.

Another advantage of LOCTITE 3921 is its ability to cure under LED light, rather than ultraviolet light, to offer superior membrane fold protection. LED light curing is less expensive and less cumbersome than UV curing and does not require special safety equipment.

LOCTITE 3921 offers excellent performance characteristics, including flexibility, penetration, adhesion, and chemical resistance. It also carries select agency approvals for water, dairy, food and beverage applications.
