ISR 358

High-quality, high-modulus single-component SMP adhesives.

  • STR 358 combines the advantages of a belt with those of a reactive system.
  • STR 358 has a pasty consistency with high thixotropy. High initial strength (green strength).
  • Excellent adhesion on many substrates without the use of primers, for example glass with ceramic screen printing, PMMA and PC.
  • Free of solvents, di-isocyanates and PVC.
  • Excellent resistance to UV rays and aging.
  • Good adhesion on many substrates without the use of a primer.
  • Permanently elastic in a temperature range between –40 ° C and + 90 ° C.
  • Neutral, odorless and fast crosslinking.
  • Low shrinkage coefficient during crosslinking.
  • Packaging: 300 ml cartridge – 600 ml bags – 20 drums
