K Targets have a retro-reflective reflector on a circular Black KAPTON® backing with a 0.001″SILICONE pressure sensitive adhesive (psa). The K-250 targets, pictured above, withstand a thermal cycle of ± 300°F.
KA Targets have the same Black KAPTON® backing as the K Targets. The A denotes an ACRYLIC psa is used for this series of targets. The advantage of the Acrylic psa we use is that it will pass the NASA out gassing test.
