GU instant adhesive

Processing

• GU instant adhesive is applied from the dispensing bottle to one side of the dry adhesion surface, which should be free of grease and dust The adhesion surfaces can be cleaned with GU aluminium cleaner or GU PVC cleaner, dissolving, or with acetone, depending on the resistive properties of the material surfaces. The adhesion surfaces are joined within the film formation time of the adhesive and compressed until the necessary functional hardness is achieved
• GU instant adhesive cures as a result of humidity and temperature. Owing to the relatively low viscosity, GU instant adhesive is not capable of bridging adhesive gaps > 0.1 mm
• When gluing the external glass strip seals in window construction, ift-Rosenheim recommends that, as well as gluing the mitre cut using instant adhesive, the profile corner pieces of the glass pane should also be glued using a neoprene rubber filling compound or sealant in order to achieve durable impermeability to driving rain
• Gluing of aluminium: only to chemically pretreated or painted surfaces; it is not possible to achieve a durable, aging-resistant bond to an aluminium sheet without appropriate pretreatment of the adhesion surfaces. Gluing materials with different linear thermal expansion behaviour must be evaluated in respect of long-term performance, especially where fluctuating operating temperatures will occur
• When gluing silicone and TPE profiles, it is essential to carry out specific pretests owing to the variety of materials
• Application quantity: dropwise, depending on use. The open time and any compression times required can only be exactly determined through specific testing, as they are heavily influenced by material, temperature, application quantity, air humidity, moisture content of the material, adhesive film thickness, applied pressure and other criteria. Appropriate safety margins should generally be added to the guide values
• Cleaning: the cleaning of cured cyanoacrylate adhesives is usually carried out by mechanical means

Storage

• Store in original container tightly sealed, dry and out of direct sunlight
• Can be stored at temperatures between +15 °C and +25 °C
• Optimum storage temperature: +2 °C to +8 °C
