Teflon rollers (cross grooves)
Special tools for completely de-airing (impregnating) fabric and mat laminates.
A practical aid above all for multi-layer laminates.
Teflon (PTFE) is a heat- and chemical-resistant plastic that cured resin residue cannot adhere to. This tool therefore has a long service life. For the rollers to facilitate effortless work for the maximum possible time, they should be cleaned with solvent after every use.
