Pressing and pre-polymerization of the acrylic
►
T he acrylic is mixed and packed according to the instructions for use. A polyethylene foil is placed between
the acrylic and the spacer for the pressing process. Pre-press the flask at 1.5 tons at intervals of approx.10–15
minutes. After opening the flask, remove the polyethylene foil and the excess acrylic. Close the flask again
with the spacer and the polyethylene foil and press it once more with the clamp. Close the clamp, place
the flask in cold water and bring to the boil. Boil for about 30 minutes, then let it cool down. This pre-
polymerization avoids possible reactions with the acrylic monomer. Remove the flask from the clamp and
open it. Remove spacer and polyethylene foil. Before the packing of PERMALINER, the acrylic must have
reached a high degree of stiffness to avoid deformation.
Packing of PERMALINER
►
W ithdraw the ready-to-use PERMALINER from the jar with a clean spatula, place it on the acrylic and
press it on slightly. Place a new polyethylene foil between PERMALINER and the flask counter. Close the
flask and pre-press at intervals with approx. 1.5 tons. After opening the flask, remove polyethylene foil
and PERMALINER excess. Close the flask again and perform the final pressing with approx. 3 tons. For
polymerization, place the flask in the clamp under pressure.
