- Very high adhesive strength
- Viscoplastic adhesive with low foaming behaviour
- Quick reaction time with high functional strength after just 15 minutes
- Very good adhesion to a wide range of substrates, such as marble, synthetic stone, etc.
- Can be sanded and painted over
- Resistant to weathering and ageing
- Permanent formwork elements = The wood cement flat-pressed panels (24 mm thick floor panel and 10 mm thick wall panel) are used in building construction for ring beam formwork, ceiling edge formwork and lintel formwork. The formwork is encapsulated with concrete (ceilings with a thickness of 160 mm, thicker ceilings of 180 and 200 mm must be evaluated on a case-by-case basis) and remains in the element, therefore also called "permanent formwork".
- The test report 5131/2446a with expert opinion by letter from the Materials Testing Institute Braunschweig confirms that permanent formwork with wood cement flat-pressed panels (L=10/24) bonded with multi-purpose power adhesive is suitable for ceilings up to a thickness of 160 mm. Ceilings with a thickness of 180 and 200 mm must be evaluated on a case-by-case basis.
- The viscosity of 1C-PUR adhesives when processed at +15 °C is approximately double that when processed at +25 °C.
- Sunlight discolours the adhesive but does not affect the adhesive strength.
- Bonding aluminium, copper, brass: Only on chemically pre-treated or coated surfaces: these materials cannot be permanently bonded in an age-resistant manner without appropriate pre-treatment of the bonding surfaces.
- Powder-coated workpieces and all metals must always be cleaned with Aluminium cleaner type 60 (art. no. 0892 130 030 / 0892 130 031).
- Powder coatings with PTFE components cannot be reliably bonded without pre-treatment (e.g. plasma process).
- Pressing pressure: for surface bonding ≥0.015 N/mm²
- for solid wood/solid wood bonding ≥1 N/mm²
- For glue joint thicknesses ≥2.5 mm, the setting, pressing and curing times are significantly longer, glue joint thicknesses ≥5 mm are not possible.
- If moisture is expected to have an impact, the glue joints/bonding surfaces must also be sealed/protected with a suitable sealing compound!
- When gluing metal with absorbent materials (e.g. wood, construction materials etc.), moisture can gradually penetrate the glue joint through the absorbent material and reach the metal surface where it can cause corrosion damage to the metal. The metallic bonding surface must therefore have suitable corrosion protection, such as paint, powder-coating etc.!
- When bonding different materials (with different expansion properties), the glue joint dimensions must be adapted according to the long-term behaviour.
- The bonded workpieces should not be painted until after the adhesive is fully cured. If they are painted too early, blisters could form in the paint.
- As aluminium surfaces and properties are difficult to define, we always recommend that you obtain sufficient information from the supplier to enable you to choose the appropriate pre-treatments for your particular bonding application. Sufficient preliminary tests are necessary.
- In the production and processing of stainless steel, auxiliary materials such as wax, oils, etc. are often used which cannot be simply wiped clean. It has been shown that after cleaning with solvents, grinding or (even better), sandblasting the surface, followed by repeated cleaning with solvents delivers considerably better bonding results.
- Zinc-plated sheets should always be protected from permanent moisture. To prevent the formation of "white rust", any moisture that occurs must be prevented from coming into contact with the bonding surface!
- Bonding larch: 1K-PUR adhesives must never be used for bonding larch surfaces in outdoor areas. The substance "arabinogalactan" which is contained in the wood, or forms within it, considerably weakens the bonding strength! No problems have been identified with PVAC and EPOXI adhesives.
- When bonding solid wood, the adhesive should preferably be applied to both bonding surfaces.
- The adhesive is mildly foaming and is therefore well-suited to use on slightly uneven surfaces. The pressing time must be adjusted according to the thickness of the glue joint.
- For bonding solid wood in outdoor applications, suitable tests should be performed to determine the optimum permanent bond depending on the type of wood, weather intensity, surface protection and geometry of the glue joint.
- Skin-forming and joining times, as well as the respective pressing and processing times required, are influenced by criteria such as material, temperature, amount applied and air moisture, amongst others. As a result, they can only be precisely determined through independent tests. The installer should add appropriate safety margins for the specified reference values.

*Stay-in-place formwork elements: The wood cement flat-pressed panels are used in building construction for ring beam formwork, ceiling edge formwork and lintel formwork. The formwork is encapsulated in concrete and remains in the element, giving the name "stay-in-place formwork".
The usage instructions are recommendations based on the tests we have conducted and on our experience; carry out your own tests before each application. Due to the large number of applications and storage and processing conditions, we do not assume any liability for a specific application result. Insofar as our free customer service provides technical information or acts as an advisory service, no responsibility is assumed by this service except where the advice or information given falls within the scope of our specified, contractually agreed service or the advisor was acting deliberately. We guarantee the consistent quality of our products. We reserve the right to make technical changes and further develop products. Please observe the technical data sheet!
Multi high-strength adhesive is used for gluing house door panels, stairway steps, handrails, stay-in-place formwork elements made of wood-cement flat pressed boards, baseboards, processing natural stone, metal window construction, window construction, window sills, laminated claddings, general repairs and assembly connections.
The application surfaces must be clean, dry and free of grease. For pre-treatment, please refer to the optimisation table in the technical data sheet.
Adhesive is applied on one side to one of the bonded parts as a bead, or applied over the whole surface using a toothed spatula. The bonded parts must be joined within the skin formation time and pressed until functional strength is achieved.
