Polyonics has developed two high-temperature aluminum materials that use a special white top coat that resists yellowing at high temperatures and is thermal transfer printable. These materials offer an acrylic adhesive system or a silicone adhesive system for the ultra-high temperature identification of coils, slabs and rolls that are identified after being removed from a furnace environment. The XF-803 has a silicone adhesive and is used in applications where temperature can reach up to 600C. The XF-807 is based on the the XF-803 top coat chemistry and has a high temperature, aggressive acrylic adhesive that is rated up to 350C.
