Technical features Supplied dimension: Decided through trade agreements Dimensional tolerances: - Lenght and width: decided through trade agreements in compliance with standard ISO 1 8775 Wood density: 450-^900 kg/m3 (measured in compliance with Formaldehyde emission: Formaldehyde emission is in compliance with El Alpilignum is not a finished product and, therefore, its resistance to light also depends on the cycle and Date of compilation January 2011

chemical nature of the finish. The buyer is advised that discolouring may occur. It is recommended that the buyer performs preventive tests according to the particular purpose and intended use, in order to optimize results. Mechanic aspect: The mechanical characteristics of the Alpilignum depend on the cycle and chemical nature of the finish and the type of support. It is recommended that the buyer performs preventive tests according to the particular purpose and intended use, in order to optimise results. Being a natural wood product, Alpilignum may vary with recommended that the buyer...

Alpilignum can be glued on all wood supports by means of urea glues. Different kinds of supports need to be tested and assessed on a case-by-case basis. The quantity of glue to be used per square metre depends on the base type and thickness, on the veneer structure (quartered cut, tangential cut, burl, etc.), on its thickness and on the type of pressing. It is generally advisable not to use more than 150 g/m2 of glue at pressures ranging from 1.5 to 5 bars. The advisable veneering temperature can range between 85°C and 120°C. The glue can be blended with organic or inorganic excipients to...

Glueing with vinyl glues Alpilignum veneer can be glued on all wood supports by means of vinyl glues. Different kinds of supports need to be tested and assessed on a case-by-case basis. Because of the thermoplastic features of this type of glue, the quantity to be applied must be carefully measured according to the type of veneering, the base and the press, in order to avoid undesirable passing through, which would be difficult to eliminate during sanding. It is generally advisable to use between 80 and 100g/m2 of glue, at pressures ranging from 1.5 to 3.5 bars. The advisable veneering...

The transversal sanding process with sandpaper 120-150-180 grit must be carried out with low strenght and in any case it may cause some microgroove traces and superficial rift mainly on the Alpilignum lime wood based. Date of compilation January 2011

Varnishing Like all other types of wood, varnishing process of Alpilignum must be done with a suitable product, capable of protecting and preserving the wood as much as possible from chemical and physical deterioration (photodegradation, thermal decay, etc.) as well as from mechanical degradation (scraping, crashes, etc.). Multilaminar wood can be stained without any particular problems, and it is advisable to do it. Alpilignum can be varnished with any product or method recommended for wood treatments. However, the best results are achieved by selecting, among the different classes of...
