New AQUACOAT 2661 PVC coating available now


The new AQUACOAT 2661 paint we announced in spring is now out on the market. AQUACOAT 2661 is a water borne one pack paint for coating PVC profiles in high-volume production processes. The coating provides hard-wearing, highly durable elastic surfaces, and is available in semi-gloss and a structured matt finish. AQUACOAT 2661 has been tested according to AAMA 615 for Superior Coatings, and all performed tests are 'passed' (some long-time exposure tests are still pending). In addition to the coating itself, there are also the new NMP-free water borne cleaning agents available: TEKNOCLEAN 1952-00 and 1953-00.

Additional versions of UV coatings
TEKNOLUX product line expanded


Teknos expands its range of water borne TEKNOLUX AQUA UV-curing coatings with new versions in white and colourless. The clear coat TEKNOLUX AQUA 1429 is now available in white as well. The coat is an all-round solution suitable for a wide range of application subjects to a variety of requirements.

TEKNOLUX AQUA 1728 had previously only been available in white, but can now be had as a clear coat as well. The water borne UV-cured coating was primarily designed for applications with strict requirements for the surfaces, such as kitchens, furniture or doors.

TEKNOLUX AQUA coatings are an exceptional solution for switching to modern, low-VOC coatings with short processing times.

State-of-the art coatings from Teknos
100% UV – even for LED lamps


LED lamp technology is being used more and more often for UV-curing coatings. This makes it important to keep in mind that LED lamps place special requirements on the coating. “LEDs emit monochromatic light instead of a spectrum. This means the coating has to be specifically formulated for drying at this wavelength,” explains Jørgen Ulrik Hansen, Research & Development Director at Teknos. This means that not every UV-curing coating is suitable for drying with LED lamps. Upon request Teknos is able to supply a number of UV curing coatings for the use of LED technology.

Country portrait
Teknos Denmark


Vamdrup is Teknos’ second largest production and distribution facility. An important part of our business in Denmark are wet and powder coatings providing high-performance corrosion protection for metal, as well as decorative coatings.

In the industrial wood segment, the company focuses on the window industry. “We supply more than three quarters of Danish window manufacturers and lead the market in this segment by a large margin,” says Marlene Juul Andersen, Market Manager Industrial Wood. When it comes to interior applications, Teknos primarily supplies manufacturers of panels, mouldings and furniture. Much of Teknos’ business in this field is made up of water borne and 100% UV coatings.

Coating in practice:
exterior wood

How can I improve the run off behaviour of products suitable for flow coating?

If primers and intermediate coats do not have a proper run off during the flow-coating process, this can lead to runners and colour changes in the case of primers. This is frequently the case when temperatures in the flow zone are too high and air humidity too low. We recommend targeted humidification in order to combat this. This can be achieved by either moistening the element before flow-coating or through targeted humidification of the flash off zone behind the flow coater, which leads to uniformly good climatic conditions. Investing in the necessary technology generally pays off since it significantly reduces costs and effort for sanding and re-priming.

How can I tell whether the UV curing process is complete?

There are two simple tests to determine whether the polymerisation process is complete.

(1) Tape test: Firmly place a strip of tape on the surface being treated and then remove it. If none of the paint sticks, it means the curing process is complete. There are special testing strips for this, but ordinary office tape is often used in practice.

(2) Scratch test: The service is scratched with a sharp object in a criss-cross pattern. This shows whether the coat of paint has cured all the way through.


How long will a gallium or mercury lamp last?

Gallium lamps generally have a service life of roughly 1,500 hours, while mercury lamps generally last for about 2,000 hours. But environmental conditions (pollution) and the type of use are also major factors that determine how long UV curing lamps will really last. Continuous operation is the most efficient way to use them, as turning them on and off frequently will significantly reduce their service life. The lamp’s radiation intensity should be measured with a radiometer every two to three months to ensure reliable curing. These measurements can also be conducted by Teknos’ technical customer service department.


How do I find out whether my UV lamp is performing adequately?

UV lamp performance can be determined using a radiometer which measures the intensity of the radiation emitted. EIT’s UV Power Puck and UV PowerMap models are two examples of suitable radiometers. They measure the maximum UV radiation intensity (in watts/cm²) and energy density (in joules/cm²) in UV curing applications. The necessary radiation intensity depends on many factors, such as the type of wood, coat thickness, pigmentation (clear or opaque), conveyor belt speed and number of lamps used. In practice, we recommend you to discuss the radiation intensity necessary for your specific case with Teknos’ technical customer service and then conduct measurements to monitor the defined target value.
