Processing and storage information
Surface condition
The surfaces must be dry, free of dust, oil, oxides, release agents and other contaminants.
Surface cleaning
The following cleaning agents, for example, can be used to remove dust, oil, release agents and other impurities:
Isopropanol/water 50/50
Heptane or ethanol
Acetone or MEK
Suitable other cleaning agents that do not leave any residues and do not attack the substrate.
Temperature
The most favourable processing temperature (object and ambient temperature) is between +15°C and +25°C.
Pressure
The strength of the bond is directly dependent on the contact that the adhesive has with the surfaces to be bonded. A short, high pressure (e.g. with a squeegee, pressure roller or pressure device, etc.) ensures good surface contact. The type and amount of pressure depends on the material (thin- or thick-walled, etc.) and the geometry of the components. Rule of thumb: approx. 20 N/cm².
Storage
The rolls should be stored in their packaging protected from light at a temperature between +15°C and +25°C and a relative humidity of 50%.
