SMP adhesive sealant XTREME

• Store original container tightly sealed in a dry place at temperatures between +15°C and +25°C without exposure to direct sunlight
• Polyolefins (among others PE, PP) cannot be bonded without pre-treatment e.g. plasma or corona procedures.
• When bonding to PVC, ABS, hard PS, concrete and powder-coated surfaces, priming with AdhesionPlus for plastic/wood/stone (art. no. 0890 100 62) is
• recommended.
• When joining non-absorbent materials (moisture content of material ≤ 8%), the adhesive must also be finely misted with water in order for the adhesive to fully cure.
• The bonded workpieces should not be coated until after the adhesive is fully hardened; if they are coated too early, the formation of bubbles in the coating cannot be ruled out.

The long-term behaviour of bonds between materials with different linear expansion rates must be evaluated, in particular when placed under load in areas with variable temperatures

• No general statement can be made concerning the wettability or bonding ability of anodised surfaces due to the variety, age and potential additional treatments on these adhesive surfaces, such as oils or waxes.
• Due to aluminium surfaces and properties being difficult to define, we always recommend that you obtain sufficient information from the supplier to enable you to choose the optimum 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 frequently used. These materials usually cannot be simply wiped clean. It has been shown that cleaning with universal cleaner type 60 (art. no. 0892 130 030, 0892 130 031), grinding or (preferably) sandblasting the surface, followed by repeated cleaning with solvent delivers considerably better bonding results.
• In principle, zinc-plated sheet metal must always be protected against ongoing ingress of moisture to prevent white rust formation. This includes preventing any moisture that arises from coming into contact with the bonding surface
• Powder coatings with PTFE components cannot be coated reliably without pre-treatment (e.g. plasma procedure).
• PMMA must only be glued when it is not under tension; otherwise, stress cracks are likely to occur
• The current version of the Technical Guidelines for the Glazing Industry No. 11 must be observed for mirror bonding.
