metal composite panels Joining method
(3) Adhesives
We can use a wide variety of commercial adhesives for joining and assembling Aluloyal metal composite panels. However, some types of adhesives may corrode aluminum and do not suit Aluloyal metal composite panels. For example, vinyl acetate type, widely used for timber and styrene foam, corrodes aluminum. The main adhesives suitable to adhesion between Aluloyal metal composite panels and other materials are as follows:
5: Suitable No: Not suitable
Apart from the above adhesives, we have successfully used the following adhesives for fabrication.
Notes on adhesives:
Prior to adhesion work, remove all the foreign matter such adjust, particles, grease, water, etc. from the area to be adhered.
Select the most appropriate adhesive than ensures the necessary adhesion power in the atmospheric conditions. The adhesion power depends on the surface conditions of the substrate. Follow the adhesive manufacturer s instructions
When Aluloyal is adhered to a dissimilar material, it is possible that Aluloyal will show a deflection due to the thermal expansion difference or dimension change of the material. Pre-test the adhesive before fabrication and installation.
Some adhesives may cause a distortion after hardening, as shown in the diagram. Some epoxy adhesives, polyurethane adhesives and silicone adhesives may show this kind of distortion. This distortion is usually very slight, and its visibility depends on the gloss level of the finish, the visual angle and the circumstances.
