TYPE A BOND
Produced from a Phenol Formaldehyde (PF) resin, which sets permanently under controlled heat and pressure. This forms to create
a permanent bond that will not deteriorate under wet conditions, cold or heat. This bond is recognisable by its distinct black colour.
Type A bond is specified in AS/NZS 2272 for marine plywood, AS/NZS 2271 for exterior plywood and AS/NZS 2269 for structural
plywood.
TYPE B BOND
Produced from Melamine Fortified Urea Formaldehyde (MUF) resin, which sets permanently
under controlled heat and pressure. The exterior plywood standard includes Type B bond
and is suitable for semi-exposed applications.
TYPE C BOND
Produced from Urea Formaldehyde Resin with a white glue line. Type C Bonds are only
suitable for interior use in non-structural applications, where the panel is protected from the
weather and damp environments.
