Film-forming and non-film-forming products
Absorption and evaporation in water-based products
The most limiting factor for wood penetration seems to be the increase in viscosity during the capillary penetration process. The water contained in the product is selectively removed and absorbed into the cell wall or it evaporates. The polymers remaining in the capillary or in the outer surface. The penetration is therefore relatively limited compared to an oil or solvent based product.
Film forming process
After the water removal the very small polymer particles coalesce to form a film because of surface-mediated forces. If the polymer particles are in a rigid, glassy state, a small amount of coalescent (a solvent that will plasticize the polymer) is added to the system to assist film formation.
High resistance
Film forming water-based coating exhibits high resistance in exterior, they can protect the wood for 7-10 years, without maintenance. The degradation of the film will be characterized by exfoliation phenomena and radical removal will be required for the restoration.
Oil absorption
Transparent oil based formulations exhibits the best penetrating performance, particularly in smaller capillaries. The depth of capillary penetration is regulated by liquid surface tension (contact angle between liquid and capillary wall).
Oil drying process
Oil formulations penetrate inside wood creating a chemical bond with cellulose fiber. Oils react with the oxygen and become a resinous hard matrix. This modular “open-pore” technology respects the original wood grain and natural material essence.
All the time beautiful
Oil treated surfaces exhibit a very a thin and uniform degradation after wintertime, which can be quickly washed and regenerated. Annually restoration allows to maintain perfect aesthetics and protection easily.

CERTIFICATIONS AND COMPLIANCE
Labeling of construction products
This label covers the French legislation relating to emissions of volatile organic compounds (VOC) and the impact they have on indoor air quality after the product is brought into the room.
Labeling refers to the pollutants emitted once the products are spread and dried.

The IBR Green Building Institute had tested some of our products and determined that they correspond to the highest standards of the aforementioned French VOC legislation.
