Fire-retardant coatings are essential for compliance with fire safety regulations in wood construction. Teknos is now offering a solution for interior wood panels: the new Teknos FR PANEL system. Applications include interior wall and ceiling panels in the interior or in areas which are not exposed to weathering.
The system is based on the fire-retardant, clear coating TEKNOSAFE 2467-00. This coating foams up when subjected to heat, creating an insulating layer made of microporous carbon foam, which effectively insulates the treated wood against heat. Depending on the specific requirements, TEKNOSAFE 2467-00 is used either alone or as a Teknos FR PANEL system with the clear coating TEKNOCLEAR AQUA 1331.
The coating is classified for factory manufacturing and meets requirements of Euroclass B S1, d0, as long as the quality management requirements are fulfilled. Detailed information on fire protection class, substrates and application is available on request. The new fire-retardant coating is expected to be available by November of this year.
Fourteen storeys tall with a breath-taking view of the Norwegian harbour city of Bergen and scheduled for completion in November 2015, the 51-metre tall “Treet” is the largest timber apartment building in the world. It is being built by BOB BBL, which is one of Norway’s largest housing construction companies with its inventory of 22,500 domiciles.
The building consists of a supporting wooden frame structure made of gluelams and pre-fabricated, stackable building modules. In total, it offers space for 62 apartments, a fitness centre on the ninth floor and a rooftop terrace with a view over the Norwegian harbour metropolis. “Modern urban construction means intelligent use of space with sustainable materials, and our project shows that this can definitely be achieved with wooden structures,” explains BOB project manager, Ole Kleppe.
Fire-resistant with TEKNOSAFE
The gluelam construction elements for the road and fjord sides were coated with the fire-retardant TEKNOSAFE 2407 coating directly at the factory by the supplier, Moelven Limtre. Elevator shafts and other concealed elements are also treated with the fire-retardant TEKNOSAFE 2407 coating.
The visible surfaces of the laminated timber elements on the interior were treated on-site with the new TEKNOSAFE 2467-00 and TEKNOCLEAR AQUA 1331 clear coating. Teknos application technicians trained the craftspersons who performed the work at the construction site and equipped them with special measuring instruments. This is because the certified fire-retardant effect requires a wet film thickness of 200 μm.
“Treet is a flagship project in which we make use of innovative, intelligent solutions,” says BOB project manager, Ole Kleppe. “It combines Norwegian timber construction tradition with modern Scandinavian design. As a residential building, the Treet offers the benefits of an energy-efficient, passive house with the healthy indoor climate of a wooden structure.”
TEKNOCOAT AQUA 2580 is a waterborne topcoat which is ideally suited to industrial processes, thanks to its short drying times and excellent blocking properties. It yields very hard, robust surfaces which meet the strictest requirements. TEKNOCOAT AQUA 2580 is used in a system with waterborne primers, TEKNOCOAT AQUAPRIMER 1866 or TEKNOCOAT AQUA 1875 and is tinted at the factory.
Manufacturers already making successful use of this coating include Porta KMI Poland, one of the leading door manufacturers in Central and Eastern Europe. The decision-makers were persuaded by its high surface quality and outstanding ability to smooth out unevenness, as well as the less visible fibres of the processed MDF/HDF substrate. Its mechanical and chemical resistance also do an outstanding job of meeting the demanding requirements in this field.
“Industrial coatings for interior doors make up an important segment for us,” says Carsten Lauth, Strategic Business Director Interior Wood at Teknos. “We can offer our customers a tiered range of products. From economical volume production or maximum surface quality, we have competitive solutions for a wide range of requirements.”
With resinous softwoods, the escaping resin can cause discolouration at knots. The pigments in the resin can cause yellowing on the paint surface, especially with white opaque coatings. Preventing these discolourations requires a special primer.
Teknos developed the latest knot sealer TEKNOCOAT AQUA PRIMER 1867-50 for this very purpose. The acidic white primer is specially designed for knotty pine wood on interiors. TEKNOCOAT AQUA PRIMER 1867-50 binds the colour substances in the resin and ensures that they remain inside the wood. This prevents knots in pine from causing discolourations in the topcoat treatment with white or light opaque paint.
TEKNOCOAT AQUA PRIMER 1867-50 is expected to be available in November 2015.
Extremely high transparency, very good adhesion and an outstanding cost-to-benefit ratio are optimum conditions for high-volume coating for general interior use. And that’s just what the new waterborne clear coat TEKNOCLEAR AQUA 1331 was designed for.
TEKNOCLEAR AQUA 1331 is still highly transparent if applied in two or even three coats. A typical structure consists of two 150 g/m2, on untreated or stained wood. The product is also ideally suited to woods such as oak, meranti or iroko. TEKNOCLEAR AQUA 1331 is easy to work with and can be applied with all spraying methods.
Initial practical experiences in Poland confirm the benefits the product has to offer: easy to work with, good surface quality and, above all, a highly attractive cost-to-benefit ratio. This makes TEKNOCLEAR AQUA 1331 an excellent choice for economical, high-volume production.

This specialist wholesaler supplies woodworking tradesmen and industrial operations in Belgium, Luxembourg and the neighbouring regions of Germany. Since the autumn of 2013, the Teknos sales partner has also been operating in Flanders with its new logistics site in Zandhoven and expanded external sales team.
Both sites are equipped with Teknos tinting machines. The company also runs a cutting-edge training centre in Eupen with spray booths and overhead conveyors. “We don’t just consider ourselves a paint supplier. We also make it a major priority to provide qualified consultation,” says Managing Director, Christoph Klüttgens.
Hendrichs has long relied upon Teknos for industrial wood coatings. “We have been selling Teknos coatings for ten years and have many long-term customers who have had very good experience with them,” says Sales Manager, Didier Kirch. “Teknos has a well-developed product range which does a great job of covering the requirements of modern window and door production.”
Renaming of GORI products
More than six years after acquiring the GORI Industry division, and to streamline the primer and filler/ intermediate product assortment, Teknos will now be phasing out the brand name GORI for primers and fillers/ intermediates, and will be changing the product names as of beginning of 2016.
For instance, GORI primers will be renamed Teknos AQUAPRIMER, while GORI intermediates will receive AQUAFILLER designations. Important for customers to acknowledge is: Only the product names and ordering information are being changed. The products themselves will still be available in the same quality and formula.
Customers will receive a detailed list of the products and versions affected in time for the switch, complete with all the new ordering information. Your local Teknos contact person will be glad to assist you with any questions you may have.
“Since the acquisition of the GORI Industry division, the teams in research and development, sales and application technology have been merged, and Teknos is now known in markets where we were not highly active under this brand until 2009,” says Product and Marketing Manager, Søren Juhl Hansen. "The general pressure keeping a streamlined product assortment alive and vivid is why the time has come to contract on a single brand. It is important to keep in mind that we are not changing the tried-and-true GORI formulas, but only renaming the products. Customers will still have a complete range of high performance products in the high quality they are used to.”

Meranti is a popular wood in window construction. Red and yellow meranti are the most widely used of the roughly 150 species. However, fluctuations in gross density affect durability and thus the coating needed. The most important question: does meranti need chemical wood protection?
Based on its long-term experience, Teknos expressly recommends impregnation for durability class 2 or poorer. Here’s what this means for the species of meranti typically used in window construction:
|Wood species||Gross density
(acc. to EN 350-2)
|Light Red Meranti (SHLR)||≥ 0,45||Class 3-4||with wood protection|
|Dark Red Meranti (SHDR)||≥ 0,55||Class 2-3||without wood protection|
|Gelbes Meranti (SHYM)||0,50-0,70||Class 3-4||with wood protection|
(Table according to Thünen Institute of Wood Research, coating recommendation from Teknos)
Teknos recommends the following system as an optimum coating for meranti woods in window construction:
(if necessary, see above)
