Product
Birch plywood (Riga Ply) bonded with waterproof phenol resin
adhesive and overlaid on both the sides with a phenol film (grade F/F).
Film colour
Normally chestnut brown or dark brown. Other standard colour are light brown
transparent, dark brown, yellow non - transparent and transparent, green,
colourless, black, grey, red. Other colours on request.
Under transparent films BB grade veneer is applied.
Applications
Advantage
Environmentally friendly, durable, workable, hygienic, not smelling and
don't give taste to food-stuff, easy to clean, wear-proof, weather and
water-proof, resists commonly used chemicals. Riga Form for shuttering
can be re-used many times.
Gluing classes
Plywood is glued with waterproof phenol formaldehyde resin adhesive. Bonding
is resistant to weather and boiling water. It meets requirements of the
following standards:
EN 314 / 3rd class;
BS 1203 / H4 (previously WBP);
DIN 68705 Part 3 / type BFU 100.
Formaldehyde emission
In accordance with the standard EN 13986 formaldehyde emission
meets the Class E1 requirements. Test method EN 717 Part 2.
Overlaying
A smooth phenol film, which is hot-pressed onto the surface, is used as an
overlay. The film is composed of a base paper and phenol resin that is
impregnated into the base paper. Film weights 120g/m2, ~170g/m2,
220g/m2. Overlaying with higher resistance to abrasion and
multi-layer overlaying are also possible (respectively 240g/m2,
440g/m2 etc.). Multi-layer overlaying gives superior wear resistance.
Overlaying characteristics
Overlaying surface is smooth, glossy and hard. It withstands abrasion, it is
weather and moisture proof and resists commonly used chemicals, dilute acids and
alkalis. The surface is easy to clean with water or steam wash. Abrasion
resistance according to the Taber test (EN 438-2): depends on
applied film, conditions of product storage and application, thickness of film
(see below) a.o.
It is possible to obtain overlaid plywood resistance to wear
even above 10 000 revolutions.

Edges sealing
Edges of the panels are matched with the face against absorption of moisture
by using acrylic paint. Other colours are available and the edges may be
unsealed at customers' request.
