The care and beauty of wood through years.

Traquisa, wants to make a little history of how it has evolved over the years, about conservation and beauty of wood.

Before Christ

At the beginning, the most important was the preservation of personal objects of daily use. The Chinese lacquer was developed, as coating to preserve them, being an art and a technique, that lasts until today.

Introduction of Chinese lacquer in Europe

lacachina4aFrom the eighteenth century was introduced in Europe, especially for the decoration of furniture and marquetry. Over the years, new products were developed. As, fatty acids oils: linseed , tung, castor oil, etc., that mixing between them, we can get a better coating: as teak oil wood to preserve outdoor wood... 

 

Development of new coatings: 1850 Nitrocellulose

CeluloideIn 1845,  german Christian Schönbein discovered the nitrocellulose, that making different combinations, we could obtain  very good results in coatings, for their hardness and water resistance.

Later, new applications were discovered. About 1865 appeared Celluloid was the trade name mixing nitrocellulose and camphor (plasticizer, with a flash point of 66 ° C), who became famous as negative film, being very flexible, transparent and resistant to moisture, but highly flammable.

bolasdebillarFrom the twentieth century were developed improvements in the composition of the nitrocelluloses, depending on amount of nitro, solvent type, plasticizer, and later by admixture with resins, favoring its application in the interiors, through brush or spray.

In 1920, the DuPont Company and Ford Motor, developed a nitrocellulose car. This new application brought something very important for automotive industry: the color, because the cars were all black. Now you could choose what color you wanted for your Ford.The marketing was born.

Development of synthetic polymers: Polyurethanes

In 1937, Otto Bayer synthesized polyurethane by the condensation polymerization reaction between polyols and diisocyanate.
There are two types according with their behavior versus temperature: thermoplastic or thermosetting, for the coating sector must be thermoplastic and  high-density 150 to 1200 kg / m.3.

Esponja hecha de poliuteranoPolyurethanes gets hard layers and resistant to inclement weather. The development has been great over the years. Today, there are companies that do polyurethanes taylor made, depending on application and conditions to maintain.

  

Developments taylor made: Lasures

The lasures was born in France, as protection of wooden house that are in the mountain areas. We can say that they are products taylor made in accordance with requeriments with resins or mixtures of resins last generation, that offer high resistance to moisture, UV rays, heat, transparent (not before), elastic, water repellents, fungicides and insecticides, achieving durability.
