A chain approach to the introduction of waterborne coatings for the dutch joinery industry
Stricter legislation on the use of solvent borne coatings forces the Dutch joinery industry to consider alternative primer systems. A logical choice is to switch to water borne primers. However, these coatings are used in the typical Dutch way of building. The method of construction of houses in The Netherlands starts by putting up window frames and subsequently building brick walls around them. Therefore, during the construction phase, the primed wood is exposed to moisture (rain), cement and damages. Thus, attention should be paid to the performance of a waterborne coating in the first months after application. It is known that water borne coatings improve their performance after a longer time of drying but might be critical if the film formation process has not been fully completed. This study describes the way in which the performance of the water borne primer systems has been evaluated in the Netherlands. The evaluation of the performance is a necessary part in approving joinery products for quality certification. Two of the main bottlenecks in performance evaluations are (1) the variety in industrial application methods of the primer and (2) the variety in climatic conditions during drying. Therefore, it was decided that products should be evaluated with certain minimal drying conditions for product approval. It was agreed that the complete Dutch joinery industry has to fulfil these minimum conditions. Due to a higher sensitivity to application and drying conditions of water borne coatings compared to solvent borne coatings, a 'chain approach' was necessary to guarantee a high level of quality of the coated window frames and doors from joinery factories to the building site. This chain, along with its bottlenecks is described in this paper. In order to switch to water borne coatings, several joinery industries will have to invest to obtain a certain level of product performance. This could affect their position in the market due to increased costs compared to their (foreign) competitors. This paper will evaluate several investment scenarios and how they relate to small, medium and large joinery industries.
