Makrolon® the construction material – answers from the trade
______________________________________________________________

Can I drill holes in Makrolon® sheets?
In principle, yes. However, please note the following:
  1. The distance between the center of the hole and the outer edge of the sheet must be at least twice the diameter of the hole, and not less than 6 millimeters.
  2. Screws should only be screwed to a tightness that allows the Makrolon® sheets to shrink or freely expand in response to changes in temperature. Do not use bevel-headed screws, as these can cause cracks.
  3. When fastening, make sure that the Makrolon® sheet is not overstrained by local compressive forces. Use washers or linear frames to distribute the pressure. Fastening holes should always be drilled slightly too large to allow for expansion and shrinking.

Can I bond Makrolon parts together?
Yes.
The easiest and most cost-effective way of bonding Makrolon® parts is to use solvent adhesives such as Ruderer 108 or Ruderer 118 (supplied by Ruderer). You should first clean the surfaces to be bonded, then apply the adhesive sparingly to one surface only. Then, immediately place the surfaces together and press on the join for a short time. The bonded parts can be moved after just a few minutes.

What´s the best way of cleaning Makrolon® sheets?
Makrolon® has a poreless surface to which dirt finds it difficult to adhere. Dusty sections are wiped down with water and a soft cloth or sponge, never rubbed down dry.

For thorough cleaning, it is advisable to use a non-scouring detergent. Paint splashes, grease and putty residues can be removed before they harden by lightly rubbing with a soft cloth which has been soaked in ethyl alcohol, isopropanol or petroleum ether (boiling point 65 °C). Spots of rust can be dealt with using a 10 percent solution of oxalic acid.

Mechanical cleaning systems (for example systems which use rotating brushes or wipers) should never be used on Makrolon®. Even if plenty of washing water is applied to the brushes, they may still scratch the sheet surface.
