The face edges are chamfered to form a small “V”. Neoprene or polyurethane elastic adhesive Wall ® Corian The design versatility and performance features of DuPont™ Corian® - the availability of  

different  

colours  

and  

aesthetics,  

custom  

colours,  

textures  

and  

finishes,  

the  

ability  

to  

  

 shape and form the material, and its exceptional durability and renewability - have led a number of architects and designers to use DuPont™ Corian® for exterior applications. These have included street signage and benches, bus stop canopies and shop facades, and more recently even façade cladding. To satisfy this growing interest, DuPont has developed a testing program to evaluate the potential of DuPont™ Corian® for exterior applications.

 commercial or residential building façades. In general, DuPont™ Corian® offers good resistance to UV rays, but certain colours perform better than others in terms of weather resistance and fading. While the physical properties of DuPont™ Corian® are not adversely affected by outdoor exposure, surface gloss can be reduced. Contrast between veining and background colour may be reduced and slight background colour changes may be observed over time. These changes can be removed by periodic sanding, but this refurbishing step is not always practical, such as in cases where DuPont™ Corian® is used for covering large architectural surfaces like building façades. The table on the right-hand page shows which colours are most suitable for exterior cladding. When using DuPont™ Corian® in exterior applications, it is especially important to mount the material on a substrate or sub-frame using a method that allows for the thermal contraction/expansion of the material.
