Two-component epoxy resins – DELO-DUOPOX DELO Industrial Adhesives
Properties of DELO-DUOPOX adhesives, casting resins and fillers:
Good resistance to chemicals and heat
Tension-equalizing
Specific products with outstanding thermal conductivity
Application areas
DELO-DUOPOX adhesives, casting resins and trowelling compounds are two-component epoxy resins curing at room temperature after mixing of the two components. They are predominantly used as adhesives and casting compounds in electronics, electrical engineering, mechanical engineering and tool construction.
Many DELO-DUOPOX products are filled in DELO-AUTOMIX double chamber cartridges and can be easily mixed and dispensed by means of dispensing gun and static mixing tube. These products are suitable for the use in the entire industry. You can draw further information from the DELOAUTOMIX selection chart and instructions for use.
DELO-DUOPOX trowelling compounds are two-component, filled, fast-curing epoxy resins and are used for coating, trowelling, filling, sealing, adjusting and equalizing in mechanical engineering and aggregate construction.
Preparation of the components to be bonded
The contact surfaces must be free of oil, grease and other contaminations in order to achieve optimal bond strength. We provide our cleaners DELOTHEN. You can draw more detailed information from the technical information “DELOTHEN Cleaners”. After cleaning, adhesion to the component can be further improved by means of surface pretreatment. You can draw additional details from the written information on surface pretreatment.
The suitability and strength of the adhesive are to be verified on original components under application-specific conditions.
Preparation of the adhesive
Before mixing, the components containing fillers must be homogenized by stirring. The data sheet and specification values are exclusively determined with components of the same batch and are only valid in this combination.
Processing
Open containers:
2-component products consist of the components A and B producing the ready-made adhesive only after proper, homogeneous mixing in the correct ratio. Due to the exothermal curing reaction, large preparations should be mixed in several portions or flat vessels for a better heat dissipation. In particular, filled products must be stirred properly and homogenized before use from an open container.
Weigh out the components A and B in the mixing ratio indicated. Mix the mixture properly, i. e. free of streaks, in a suitable vessel. It must be ensured that no air is stirred in and all weighed ingredients are mixed homogeneously. Processing must be completed within the pot life or processing time specified. Scrapers or notched trowels are suitable for application. In case of lathing or milling, the depth of cut and the processing speed should be possibly low in order to achieve a high dimensional stability.
