SECURE 8140 series  
 

Plastics are an essential engineering material with versatile processing and wide variety of performance for modern product assembly. SECURE 8140 series are formulated for structural bonding of such polymeric substrates. SECURE 8140 series cured with outstanding bonding strength on plastics when exposed to ultraviolet light. SECURE 8140 series possess toughen flexibility with excellent peel and impact resistance. SECURE 8140 series are best suited for bonding, sealing and tacking of plastics molded components such as housings, chassis, sub-assemblies, printed circuit boards, flexible printed circuits, etc used for product assembly and mounting. SECURE 8140 series are also suited for high strength tacking and enforcement of components and connectors.

- Single component adhesives
- Rapid securing with ultraviolet light curing
- Secondary visible curing systems for versatile assembly
- Best suited for high speed and high volume production
