US’ Flexcon, an innovator in adhesive coating and laminating, has announced an expansion of its L-59FR series flame-retardant adhesive portfolio. The Flexcon L-59FR series, featuring a self-extinguishing, non-halogenated flame-retardant adhesive, is now available in both 2.0 mil and 4.0 mil adhesive coat weights as either a transfer tape or coated film.

All products now meet industry leading UL 94 flammability standards. Testing has been expanded on the 2.0 mil products to comply with components of Federal Aviation Regulation 25.853, Appendix F, for vertical 12 second and 60 second burn, heat release, and smoke density. Coated films meet Federal Motor Vehicle Safety Standard 302 for a range of automotive applications, the company said in a press release.

Flexcon L-59FR series high-tack and high-shear adhesive provides excellent adhesion to polypropylene, stainless steel, polyethylene, acrylic, and glass surfaces within aircrafts and motor vehicles. This self-extinguishing, non-halogenated adhesive is available in nine standard constructions of Flexmount transfer tapes and Flexmark coated films.

“The expansion of aviation testing enables our adhesive products to be fit for use in a wider range of aerospace applications, including assembly of interior structures like wall panels and ceiling panels, which are commonly updated in the aircraft during the standard retrofit process every 5 to 7 years. All products, including high and low adhesive thickness, boast the highest UL 94 vertical burn rating of V-0, which is superior to competitive products in the industry. Converters and OEMs now have another adhesive choice that offers superior quality and performance to products available today,” Jordan Smith, manager, marketing and product management at the company, said in a statement.
