High modulus polyurethane sealant and adhesive

Everbuild Tecnic Puraflex 40 is a high modulus, one component, PU sealant and adhesive which adheres strongly to most substrates. Provides excellent mechanical resistance (Shore A 30-40), resistance to most common chemicals and can be overpainted when cured.

  • Bonds to concrete, wood, metal, aluminium, polyester, glass, uPVC, stone, ceramics, etc.
  • Over paintable with gloss and emulsion.
  • Good sea water resistance.
  • Can be over painted with oil and latex paints.
  • Specifically designed as an easy flow flooring grade for all concrete saw cuts and floor slab expansion joints, where abrasion resistance is required.
Usage
  • Sealing and bonding metal panels and trim.
  • Expansion joint sealing in concrete panels and floor joint.
  • Sealing in applications subject to vibration and mechanical abrasion.
  • Multitude of sealing and bonding applications in the construction and engineering markets.
  • Bonding in container fabrication.
  • High traffic floor joints such as those found in garage forecourts, warehouse, factory floors, sports arenas, shopping centres etc.
Advantages
  • Bonds to concrete, wood, metal, aluminium, polyester, glass, uPVC, stone, ceramics, etc.
  • Over paintable with gloss and emulsion.
  • Good sea water resistance.
  • Can be over painted with oil and latex paints.
  • Specifically designed as an easy flow flooring grade for all concrete saw cuts and floor slab expansion joints, where abrasion resistance is required.

Flexibility +/- 25 %

Elastic Recovery

~85 % (100% elongation at +23 °C ISO7389)

Service Temperature

-40 ˚C to 80 ˚C

Joint Design

Max joint depth should should be half joint width. If deeper, use EVERBUILD FIX AND FILL FOAM or EVERBUILD JOINT BACKER ROD.
Furthermore, ensure that the joint design only permits adhesion to two surfaces, as three-sided adhesion will impair flexibility. BOND BREAKING TAPE, EVERBUILD BACKER ROD OR CURED EVERBUILD FIX AND FILL will remove third-side adhesion.
Reference should be made to the recommended joint ratios.
Joint range of 10 - 35 mm.
