Transportation
Bumper Modules

Truck end users demand maximum durability from their vehicles. Day-to-day vehicle use in harsh environmental conditions is combined with tough operating conditions involving frequent low speed impacts due to parking, loading and general driving conditions.

Sika has formulated a range of specialist material for assembly of bumper system applications. SikaForce two-component polyurethane combines high strength with good flexibility. SikaFast twocomponent methyl methacrylate structural adhesive provides high strength and excellent impact resistance with low surface preparation. Both solutions provide excellent adhesion to glass fibre reinforced plastics (GRP/FRP), polyester sheet moulding compound (SMC), reinforced reaction injection moulded (RRIM) polyurethane,engineering thermoplastic alloys, coated steel and aluminium.

Why Use Bonded Bumpers?


-		Higher impact resistance than vibration welded and mechanically fastened systems to reduce repair costs and frequency
-		Reduced weight to improve fuel consumption
-		Lower component cost, due to the ability of adhesives to bond different types of plastics together that would be difficult toassemble via vibration or ultrasonic welding, to reduce cost
-		Compensates for differentials in co-efficient of linear thermal expansion (CLTE) in different types of materials (e.g. metals toamorphous thermoplastics)
-		Improved aesthetics - no visible fixings

Technological Benefits


-		Wide range of mechanical properties to suit individual customer application requirements
-		Excellent compatibility with polycarbonate alloys, ABS (Acrylonitrile
-		Butadiene Styrene), styrenic alloys, RRIM (Reinforced Reaction
-		Injection Moulded polyurethane), SMC (Sheet Moulded Compound) and polyester glass fibre
-		Broad range of processing speeds to suit customer manufacturing process requirements
-		Highly resistant to heat and aggressive climatic conditions
