Product
Birch plywood, which is glued with colourless urea- formaldehyde adhesive
resin modified with melamine. The panels have been developed for laser
cutting.
Possible overlays
In order to protect the surface from spots and facilitate further
processing, it is possible to coat the plywood with prime (UV hardening),
acid curing lacquer or melamine film, for example: Riga Laser Prime,
Riga Laser Lacquer or Riga Laser Mel.
Further processing
Riga Laser plywood is intended for laser cutting or for
processing with ordinary cutting tools. It is possible to apply to the
surface various synthetic materials: films, laminates, as well as paint or
lacquer.
Application
Widely used for die-cutting plates in cardboard packing industry.
Riga Laser plywood is suitable for indoor use and applications
where colourless glue is required: for furniture, toys and sports
equipment
Advantages
