FAQ - Application

This is a mechanical or chemical attack on the material surface. Such damage can only be removed by mechanical grinding and polishing. In many cases, it makes sense to replace the component.

Owing to the manufacturing process (e.g. rapid cooling), the moldings may contain high internal stress levels. Fastening methods unsuitable for the material (e.g. pointwise fastening) may also provoke higher stress levels in the moldings (mechanical stress).

When exposed to a corrosive medium (e.g. cleaning agents, screening inks, solvent vapors), these components may show stress cracking. Parts should therefore be produced so as to contain low stress levels (by means of higher mold temperatures, slower cooling, higher demolding temperatures) or subsequent annealing, and should if possible be fastened over large surface areas. Moreover, any cleaning agents used should be compatible with PLEXIGLAS^®.

Prior to surface treatment, we recommend cleaning the part by blowing it down with ionized air or washing with a cloth made of glove-lining fabric and warm water to which some dishwashing liquid or ANTISTATISCHER KUNSTSTOFF-REINIGER UND -PFLEGER from Burnus has been added.

Minor scratches can be polished away with "Acrylglas-Polier & Repair Paste" (AGP) from Burnus. Deep scratches must first be ground with coarse wet abrasive paper, then with ever finer grit sizes (up to 1000) until the scratches are only slight. Then polish with AGP, which is available from autorized distributors of PLEXIGLAS^®. Mechanical polishing with a buffing wheel and wax is also possible.

Like many plastics, PLEXIGLAS^® is a typical non-conductive material with good insulation properties, i.e. it has high surface and volume resistivity. Its surface may therefore become electrostatically charged after mechanical cleaning by rubbing with solid objects. Prior to surface treatment, we recommend cleaning the material by blowing it down with ionized air or washing with warm water and dishwashing liquid, or wiping with "ANTISTATISCHER KUNSTSTOFF-REINIGER UND -PFLEGER" from Burnus.

Crystal-clear PLEXIGLAS^® standard molding compounds show excellent resistance to aging and weathering, including natural UV radiation. This means the material does not turn yellow or become brittle, even after many years of outdoor exposure in various climates all over the world. PLEXIGLAS^® retains its superior optical and mechanical properties for many years.
