ThermoFlex® Puff
ThermoFlex® Puff is an intumescent (swells as a result of heat exposure) film with a matte finish.
Instructions for application to moisture-wicking materials: Damp a cloth with rubbing alcohol (isopropyl alcohol),
then rub it into the area on the garment you want to apply your design. Allow it to dry and apply your material.
This will allow better adhesion to the garment. Instructions for application to dazzle cloth and shiny polyester:
We highly recommend that you TEST prior to doing large runs. Coated polyester can routinely cause adhesion issues.
