Applications
Benefits
▪ Cold temperature properties ▪ Ip/Bd structure provides good crack resistance, better damping performance, good compatibility with BR, hydrocarbon and rosin resins ▪ Good solubility in aliphatic, aromatics and ethers ▪ High reactivity due to Ip/Bd structure ▪ Improves expansion in foams ▪ Improves heat and abrasion resistance
▪ Sealants ▪ Sprayable/foam-able sealants ▪ Anti-flutter adhesives ▪ Oil replacement
L-IR-390
▪ Good bonding to wide variety of substrates ▪ Joining of dissimilar materials ▪ Improved adhesion to oily surfaces ▪ Softness ▪ Higher Mw helps prevent sagging
▪ Spot welding sealants ▪ Anti-flutter adhesives ▪ Flexibility improver for Multi-substrate bonding
L-IR-403 L-IR-410
▪ Better processability and reactivity in mastic sealants (BR, SBR, IR) ▪ No migration ▪ Compatible with a broad range of vegetable oils ▪ Higher Mw helps prevent sagging
▪ Mastic sealants ▪ Extrudable rubber-based patches ▪ Oil replacement ▪ Underbody coatings
L-IR-30 L-IR-50
▪ Sprayable/foam-able sealants ▪ Spot welding sealants ▪ High damping foams and acoustic baffles (LASD)
▪ Excellent sound and vibration damping ▪ High tan δ over a wide temperature range ▪ Improves reactivity ▪ Improves expansion in foams
