SMP adhesive sealant, 2-component

• Application times are reduced to around half the time at +30°C and extend to around double the time at +10°C.


• 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

Bonding metals

• 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 cannot be simply wiped clean. It has been shown that cleaning with the universal cleaner type 60 (art. no. 0892 130 030, 0892 130 031), grinding or (preferably), sandblasting the surface, followed by repeated cleaning delivers considerably better bonding results.


• In principle, zinc-plated sheet metal must always be protected against ongoing ingress of moisture and standing water to prevent "white rust formation". This includes preventing any moisture that arises from coming into contact with the bonding surface


• When bonding metals to absorbent materials (e.g. wood, construction materials, etc.), the moisture can be slowly transported through the bonding gap by the absorbent material onto the metal surface, where it can cause corrosion damage to the metal. The metallic bonding surface must therefore have suitable corrosion protection, e.g. paint or powder coating!


• Will not reliably adhere to powder coatings that contain PTFE without pre-treatment (e.g. plasma treatment)
