temperatures of up to 250°F (121°C) for 30 minutes. The actual temperature and
time performance may be higher or lower for a given application. Clean removal
can vary dependent on surface type, processing conditions (such as multiple
bakes), type of paint involved as well as the temperature of the surface at removal.
We recommend testing the product under your conditions to determ ine if it meets
your needs.
• Excellent transfer resistance to “difficult to remove from” surfaces like EDPM
rubber moldings.
• Tests indicate it is better than conventional masking tapes for sunlight resistance,
it is still advised that it not be subjected to outdoor exposure or prolonged periods
of sunlight as tape may become difficult to remove.
