Hybrid Polymer Crystal

The blaugelb Hybrid Polymer Crystal is a one-component, permanently elastic sealant and adhesive that cures crystal-clear. Formulated on the basis of a hybrid polymer, it exhibits high initial adhesion and rapid full cure.

Thanks to its crystal-clear transparency, the blaugelb Hybrid Polymer Crystal is ideal for bonding between or to glass indoors, but also for a large range of other uses (not as a glazing sealant). The blaugelb Hybrid Polymer Crystal is waterproof and weather-resistant and also resistant to many chemicals.

Thanks to its high initial adhesion, it can usually be applied without primer to almost all – even wet – substrates encountered in construction.

In the construction and industrial area, for strain-free structural bonding and sealing of glass, metal, hardwood, plastic, concrete, polystyrene, cork, etc. Very suitable for bonding and sealing metal constructions, in ventilation systems, automotive manufacturing and many more areas.

Glass, metals (steel, aluminium, brass, zinc, etc.), cork, concrete, stone (except porous natural stone types), enamel, glass, wood, HPL, plastics (polystyrene, polycarbonate, PVC, polyamide, GRP). Do not use on PE, PP, PTFE or silicones, PMMA or ABS.

Product benefits:

  • Universally usable for sealing and bonding
  • Crystal clear
  • Very good processability
  • Moisture and temperature-resistant
  • Weather-resistant
  • Permanently elastic, compensates for unevenness and material movements
  • Silicone, isocyanate and solvent-free
  • Non-corrosive
  • Odourless
  • Exceptionally suited for time-critical application due to
  • its fast processability
  • Cured by atmospheric humidity from outside inwards
  • Very good coatability according to DIN 52452-A1*,
  • can be painted over wet-in-wet
  • Suitable for all standard construction surfaces*
  • Building material class E (DIN EN 13501-1)

*Carry out suitable pretests.
