PROALSIN Project. High-Speed Curing Primer

The primary objective of the PROALSIN project focuses on developing a versatile primer product for high-speed photopolymerization application lines. The product must address the problem of lack of adhesion in protecting decorative synthetic surfaces, especially in melamine systems.

Currently, synthetic substrates, such as melamine boards, are widely used in furniture manufacturing. Melamine boards are press-finished and are highly cross-linked and smooth, leading to adhesion problems for subsequent layers. Although theoretically these systems should not be varnished, they are coated in industrial lines to provide a higher quality and more commercially appealing appearance.

In these cases, issues of poor adhesion and moderate mechanical properties are evident and, additionally, often occur randomly.

The main challenge of this project is to introduce to the market a photopolymerizable high-speed curing system with a primer that eliminates adhesion issues on plastic surfaces and allows the application of coatings in upper layers, providing the required aesthetic qualities and suitable mechanical properties.


Project funded by the European Regional Development Fund (ERDF) and the Department of Economic Development and Competitiveness of the Basque Government.


Project within the HAZITEK program led by IRURENA GROUP in collaboration with TECNALIA.
