Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Tego film was developed in Germany around 1930 as a glue for waterproof plywood. It comprised a paper sheet pre-impregnated with a resole phenolic resin. When heated, assembled between wood veneers and then compressed, a strong and waterproof laminated plywood was formed. Most plywood at this time used other adhesives, such as casein. These adhesives were generally applied as aqueous solutions, which caused warping of thin veneers and made it difficult to achieve a solid laminate without risk of voids. As Tego film was used dry, it gave a high integrity result, solid and without risk of hidden weaknesses. This became an important factor in time, when it was applied to use in aircraft construction.
