Wurth Multi High-Strength Silicon Beige-310 ML(12Nos/Ctn)

Multi high-strength adhesive is used for gluing house door panels, stairway steps, handrails, baseboards, strips, for fixing supports for false floors, stay-in-place formwork elements made of wood-cement flat-pressed panels, for processing natural stone, for window and door construction, window sills, laminate claddings, carports, pergolas, sign fixing, as well as for general repairs and assembly.

Instructions / Application

• 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. For more information, please refer to the technical data sheet.
• 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.

Proof of performance

• Tested adhesion for stay-in-place formwork elements by MPA Braunschweig
• Tested stress group D4 in accordance with DIN EN 204 by ift Rosenheim
• Tested heat resistance in accordance with DIN EN 14257 (WATT 91) by ift Rosenheim
• French VOC emissions class A+
• Lost 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, which is why they are called “lost formwork”.
