500 is a 11 mil, one step plasma masking tape constructed of a silicone rubber/glass cloth backing coated with an aggressive high-temperature silicone adhesive. It will withstand grit blast and plasma spray process yet will remove cleanly. 500 has a higher tack than most other plasma masking tapes which allows it to easily conform to the most complex shapes of the Aircraft Industry. It is used as a one step masking tape in plasma flame spraying. It provides superior high temperature protection during both grit blasting and plasma metallization operations.
