JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
L&L Products announces a range of room temperature-curing two-component fire, smoke, toxicity (FST) compliant adhesives for simple assembly of composite parts.
Adhesives are supplied in a two-component cartridge, as well as in pails or drums. One of the components contains an epoxy-based adhesive, while the other contains an amine-based curing agent. Once the two are mixed, the adhesive adheres to the surrounding substrates and hardens.The company says its adhesives hold a high-strength bond and are designed to meet the stringent requirements of the aerospace industry. They note that a 12-second vertical burn is the minimum specification to meet FAR 25; L&L’s adhesives exceed the requirement by passing the most stringent of the tests at 60 seconds.All of L&L’s two-component adhesives have a 1:1 or 2:1 mix ratio, enabling easy working conditions using standard applicator gun sizes. Typical gel times are 5-90 minutes, depending on the material used. All of L&L’s two-component FST adhesives are developed with REACH compliance.Typical applications include bonding inserts to honeycomb panels, panel-to-panel bonding (ability to bond multi-material substrates), composite potting and fillet seals.More information: www.llproducts.com
