"Finnish birch model aircraft plywood" Tegofilm glued, quality BB

This is an exceptionally high quality plywood, which is made of Finnish birch wood, as the name shows. It has two layers of 1 mm thickness each, with lower thickness even up to three layers.The charactistic feature of this plywood is its strength and stability.

Finnish birch model aircraft plywood consists of multiple layers of wood which are glued together – in this case with tego film glue. This is a dry phenolic resin film glue which is outdoor weather resistant per DIN 68705 (corresponds to AW 100, without certificate), which means that it is both moisture and weather resistant. In the case of birch plywood with a thickness of 0.4 or 0.6 mm, the glue can be seen to penetrate all the way through. Sheets with these thicknesses are greyer than thicker plywoods but they are not, however, splotchy.

The Finnish birch model aircraft plywood we have on offer is quality BB which corresponds to the standard commercial quality. If no quality classification is given for a plywood it will always be a quality BB material. This classification means that the wood can have knots of up to 10 mm diameter and a limited number of healthy branches up to 15 mm in diameter. In addition, healthy pin knots up to 8 mm in diameter and flawed joints, face splits or overlappings up to 200 mm in length and 1 mm wide are allowed.

Thin plywoods with thicknesses up to 0.8 mm can both be cut to size or holes can be cut using only a cutter. Sawing should be done with a circular bench saw, scroll saw or fret saw; gluing with UHU hard, TESA ALL-PURPOSE GLUE or PONAL (especially in the case of large areas). Finnish birch model aircraft plywood can be painted or varnished with great results.

In architectural model making, the lightly grained birch airplane plywood is great for building stratified models, whole buildings, attached facades, ceilings or floors. Therefore it is perfectly suitable for the production of boomerangs. .
