Soudal | Polyurethane Adhesive
Soudal PU Construct is a one component Rapid Setting, gun applied, thixotropic polyurethane based construction adhesive with high bond strength and high water resistance.
Soudal PU Construct cures under the influence of humidity. Slight moistening of substrates improves curing rate and gap filling characteristics as adhesive foams up to penetrate the bond cavity.
Soudal PU Construct has a 15 minute pressing time and is fully cured in 30 minutes.
Conforms to DIN EN 204 Grade D4
Fast Curing and Strength Build-up
Filling Characteristics, Suitable for Uneven Surfaces
Clamping Increases the Bonding Strength
For Indoor and Outdoor Use
General joinery of wooden materials.
Manufacturing of door and window frames that need to match class D4 according to EN204.
For heavy duty bonding of wooden construction elements
Bonding of insulation materials (including polystyrene).
Can be used on porous and non porous construction materials, i.e bricks and concrete.
Surface Type: Various porous and non-porous substrates such as wood, concrete, bricks and other common materials in the building industry. Not suitable for PE and PP.
Surfaces should be clean, dry, free of dust and grease.
The adhesive cures under the influence of humidity. Slight moistening of substrates improves curing rate and gap filling characteristics as adhesive foams up to penetrate the bond cavity.
We recommend a preliminary adhesion test on every surface.
Application Method: Slightly moisten both substrates. Apply the adhesive by means of a manual or pneumatic caulking gun to one of the substrates. Join the parts together within 5 minutes and clamp for at least 15 minutes. Pressing the materials, during curing, is necessary to reach the highest possible end strength. PU Construct reaches 80% of its end strength after 10min (when moistened). When bonding 2 non-porous substrates, moisten only one of the two substrates. Avoid displacing of the substrates during joining both substrates together or during the curing process.
Cleaning: PU Construct can, before the adhesive is cured, be removed from tools and materials with Soudal Gun and Foam Cleaner. Cured adhesive has to be removed mechanically.
Repair: With the same material
Not suited for applications with continuous water immersion.
