The Right Technology for any Application
Lightweight bonding has become a common part of the vehicle manufacturing processes but joining substrates with different properties (like thermal elongation or polarity) presents a real challenge.
Sika offers a proven portfolio of bonding products which offer good adhesion to a broad range of substrates all over the vehicle exterior, including spoilers, fenders, hang-on parts such as doors and hoods, covers and even complete tailgates.
SikaForce® (flexible) 2C PU adhesives, 1C Sikaflex® Booster technology, and SikaMelt® hotmelts are specifically designed for lightweight bonding of mixed materials – metals, composites, woods and plastics like PBTP, ABS, and PC, as well as different blends. All three Sika technologies work well when pre-treatments like plasma, corona, or flame are utilized. SikaMelt® can also be used to bond polyolefins without the need for pre-treatments or primers.
- Hang-on parts
- Cost reduction – faster handling time (accelerated adhesive, fast adhesion build-up): shorter line, less storage time and space
- Low modulus – no read-through marks (even in winter conditions)
- Cures independent of environmental conditions
- No pre-treatment (primer) needed
