Machining
Komacel
®
sheets can be easily and quickly worked with standard tools to
process wood and metal (plastic bits and blades are required). To prevent
breaking and splitting, the tools must be sharp. Generally, you should use a
high cutting speed and slow, continuous forward feed. Normally,
it is not necessary to cool the cutting tools, but in special cases,
compressed air is sufficient. Deep notches and sharp edges can cause pre-
mature breaking of the material if too much weight is placed on the affected
area.
Welding
Komacel can be welded by normal procedures, such as hot gas, heated tool,
bending and welding, friction, etc., using common equipment. Before weld-
ing, the part of the sheet to be welded must be properly cleaned with a
cleaning agent or by machining. After welding, finishing may be necessary.
Komacel should be worked very carefully to ensure that the foam structure
does not collapse.
Bonding
Komacel will accept most adhesives for rigid PVC. The sheet surface must be
clean, dry and free of oil or grease. When choosing an adhesive, consider the
strength required, the temperature the sheet will be exposed to, cure time
and environmental safety.
When bonding Komacel to itself, the same solvent-type adhesives used for
rigid PVC will provide excellent results. We recommend Lord and IPC Weldon
products for most applications in which bonding to Komacel or another sub-
strate is required. As always, we suggest a test piece prior to full production.
Printing and Coating
Because of its smooth surface, Komacel is easy to print, paint and coat.
Although, in principle, any PVC-compatible paint can be used, these
systems have proved most suitable:
• One- and two-component acrylic paint systems
• Two-component polyurethane paint systems (DD paints)
• Screen-printing paints for PVC (binding agent basis acrylic resin/PVC
copolymerisate)
• Carbit Paint Carbithane 11 Series Low Acrylic Polyurethane and Series 12
Fixing and Storage
With a coefficient of linear thermal expansion a = 0.08 mm/m°C, Komacel
sheets vary more in length than wood or metal. When you install screen-
printed advertising boards or fix curtain walling and cladding, possible sheet
expansion has to be taken into account. The appropriate fixing method
depends on the application.
Always store Komacel sheets on a dry and even surface in heated rooms at
15 – 20°C (59 – 68°F). Sheets inside the packing must not be exposed to
weathering and solar radiation.
