Alexseal is launching its HS Prime Coat 435, helping applicators to detect imperfections, save one layer and simplify the paint job.
The new Alexseal high-solid product is a two-in-one product for priming and showcoating before applying the final topcoat, and comes with a bundle of functionalities, making the application process faster and more efficient.
Painting is a complex process involving several layers. After applying a corrosion protection primer, the uneven hull and superstructure are transformed into a smooth surface using fairing compounds and high-build surfacers. In conventional yacht new-building, this is usually followed by an epoxy-based finish primer, and the topcoat is applied afterwards. The high-gloss topcoat shall reveal unevenness that was not visible on the more matte finish primer.
This means that the first layer of topcoat has to be sacrificed to detect and rework the imperfections. With this high-solids HS Prime Coat 435, this sacrificial topcoat layer is no longer necessary, as even the smallest imperfections are visible in the glossy finish of the prime coat and can be reworked. With its polyurethane-based formulation, the prime coat offers detective functionality while other parameters ensure that the painting process is optimized, and the painters' work becomes faster and easier.
Prime Coat comes with good hiding power at a dry film thickness of approximately 50µm. The lower layer thickness leads to faster drying and higher stability compared to standard epoxy primers. Formulated with an impressive proportion of high-solid components, it leads to less VOC emission and less shrinkage while drying and is easy to sand.
