Formoa 017LT is a long open-time, single component moisture curing adhesive with high initial grab and high green strength, for bonding where an elastic structural joint is required.


  • Solventless and isocyanate free
  • Virtually no shrinkage
  • Elasticity unchanged at temperatures between -40°C and +120°C
  • Neutral reaction, odourless
  • Rapid curing that allows the parts to be handled a few hours after assembly
  • Excellent adhesion on glass and all sheet metals used in bodywork, galvanised sheet metal, aluminium and rigid PVC
  • Excellent resistance to aging and UV rays


  • Bonding of strengthening ribs on metal plates and fibreglass plates, and generally on most structures subject to continuous vibrations or between materials with very different thermal expansion
  • Bonding of metal, plastic and fiberglass substrates in the manufacture of mass transit vehicles
  • Assembly of insulating panels
  • Gluing of panels made of steel, painted metals, plastic laminate, uPVC and other plastics, to frames and metal structures
  • For bonding overlaps between metal sheets or metals and other surfaces onto which it is not possible to release weldings or mechanical fixings
  • For bonding metal profiles (U) onto glass, plastic sheets, metal panels in refrigeration industry, refrigerators, furnishing, means of transport

Method of use

Adhesion and surfaces preparation:

Formoa 17LT has very good primerless adhesion, provided surfaces are free from grease, on steel, galvanised steel, anodised aluminium and aluminium, on painted surfaces in general, on wood, glass and glazed surfaces, polyester and uPVC.
For application under severe conditions, such as under extremely wet conditions, or on porous surfaces, the use of a suitable primer can improve adhesion of the sealant.
However, on metal and glass surfaces we recommend the use of Formoa Surface Activator.

Application of the adhesive:

Formoa 017LT can be applied by a manual or pneumatic gun onto only one part. Join the parts together within 55 minutes. When compressed, the bond line thickness should not be less than 1-2mm, in order to allow the correct curing and best performance characteristics once cured.
Onto large surfaces the adhesive can be applied in parallel lines, 20-40cm apart.
