Hard Shrink
Hard shrink is a heat-shrink technique using higher temperature for shorter pass times, suitable for tougher film constructions and deeper compound curves.
Hard-shrink technique uses 130–160 °C heat with quick passes. It is faster and produces more aggressive contraction, useful on deep curves like the rear windscreen of a fastback or coupe.
The risk of hard shrink is overheating, which can damage the hard coat or distort the optical layer. Skilled installers calibrate their heat guns and time per pass to the specific film and glass.
Films like Platinum99 tolerate hard shrink well thanks to the heat-stable nano-ceramic chemistry.
