CAMX 2018 preview: L&L Products
Appears in Print as: 'Room-temperature cure adhesives for aerospace, automotive'
L&L Products (Romeo, MI, US) is presenting its room-temperature cure adhesives for applications that require fire and smoke and toxicity performance. Booth N21. Two new adhesives include L-9150 and L-9115. L-9150 is a two-component adhesive with a 1:1 mix ratio, which cures at room temperature or can be accelerated with heat. It provides high-performance bonding (work life 35-50 minutes). L-9115 is a two-component, toughened adhesive that cures at room temperature and provides high-performance bonding (work life 10-20 minutes). Both adhesives are designed for aerospace interior applications and meet the FAA fire regulations (vertical burn, smoke density and toxicity). Also in the L&L Products booth is the company’s newest technology, Continuous Composite Systems (CCS), which combines highly engineered sealants and adhesives with a fiber-reinforced composite carrier in a two-dimensional profile designed to provide strength, stiffness and rigidity in a lightweight structure. Also new from L&L Products is a structural adhesive foam, L-5920, an epoxy-based structural foam with higher strain to failure than traditional structural foams. It is commonly paired with a reinforcing material such as nylon and then designed to create an engineered structural insert. The heat-activated foaming structural material is intended for crash applications with improved strain to failure and modulus (strain energy). L-5920 has a higher vertical rise at the same volumetric expansion than its Generation 3 predecessor, L-5520, meaning it is capable of spanning larger gaps and achieving adhesion more quickly during heat exposure and thereby producing more durable bonding.
