Wood Weld is the ultimate wood adhesive & is the choice of most of the UKs major joinery companies. It bonds all timbers (hardwood & softwood) including Accoya. This bond is unbreakable once cured.

It will also bond most building materials (including ceramics, metal & plastics). It is totally waterproof and conforms to D4 specification.

Construction Chemicals Wood Weld PU

Construction Chemicals Wood Weld PU is a single component, solvent free, moisture curing polyurethane adhesive. Wood Weld PU is the ultimate adhesive that will bond most building materials to almost any other material. It is totally waterproof and conforms to D4 specification. Wood Weld PU is Thixotropic and is therefore less messy than most other polyurethanes.

Wood Weld PU expands slightly when curing and therefore gives a weld like unbreakable bond to all materials. Wood Weld PU is a rapid curing, gap filling, polyurethane adhesive which can be used to bond all timbers (even wet or dry timber), concrete, polyurethane foam, expanded polystyrene, and other porous and non porous substrates. Once polymerised Wood Weld PU is totally waterproof.

Wood Weld PU cures by mass therefore offers a high initial bond with a very fast handling strength.

 

Customers demand products that will be reliable in all bonding situations.

 

Features

  • A single part, ready to use adhesive
  • Will bond most building materials to almost any other material
  • Totally waterproof and conforms to D4 specification
  • Fast curing and gap filling
  • Thixotropic - therefore very controllable
  • The ultimate joint and shopfitting adhesive

 

Benefits

  • Thixotropic It stays where you put it, less mess
  • Rapid cure Less cramping time, saves labour costs
  • Easy to use Standard 310ml cartridge
  • High temp resistance Can be used near ovens and light boxes
  • 10min or 30min cure Flexibility of adhesive when assembling
  • No "adhesive run off" (as with liquid PUs). Less waste and no time cleaning joints

 

Uses

Wood Weld PU is a rapid curing, gap filling, polyurethane adhesive which can be used to bond all timbers (even wet or dry timber), concrete, polyurethane foam, expanded polystyrene, and other porous and non porous substrates. Once polymerised, Wood Weld PU is totally waterproof.

Wood Weld PU cures by mass therefore offers a high initial bond with a very fast handling strength.

Wood Weld PU can also be used for:

  • All joinery and shop fitting applications in particular oak framing, stair case building or where extra bond strength and speed is required.
  • Bonding natural timber and laminate floor boarding, including bonding to asphalt.
  • Can be used on resinous timber with no loss of bond strength.
  • Ideal for pre treated timber when bonding with PVA is difficult.
  • Boat building.
  • Building applications, bonding bricks etc.
  • Will also bond plastics, metals, MDF. The list is endless

 

Application

  • Ensure surfaces to be bonded are clean and free from grease, dust and any other contamination.
  • To ensure best results when cleaning use Cleaner 3 (Flammable) allow solvent to evaporate before bonding.
  • Dry porous materials usually contain sufficient moisture in order to create curing.
  • Some metals i.e. untreated aluminium and galvanised steel require over spray with water in order to achieve a quick cure.
  • Assemble before 5 minutes and apply an even pressure across the whole bond area whilst the bond cures.
  • Allow the bond to fully cure usually 25-30mins.
  • Allow excess adhesive to fully cure then trim off with a sharp edge, do not try to wipe of uncured adhesive as this will only make final cleaning more difficult.

 

How It Works

Wood Weld PU is a moisture-curing adhesive, therefore as soon as soon as it is dispensed from the cartridge it is exposed to moisture and begins to slightly expand, when the timber is cramped together this expansion continues and forces the adhesive into the grain of the timber at the same time as curing.

This action welds the timber together extremely fast giving a joint that is stronger than the timber.

 

Easy to Use

  1. Select your timber
  2. Apply a small amount of Wood Weld PU
  3. Cramp your joint
  4. Wait 10 or 30 minutes, depending on the setting time selected
  5. Un-cramp, joint bonded
  6. Trim off excess adhesive when cured
