UNE 48254 Paints and Varnishes Standard Test for Determination of Forced Reflection Curves of Paints

EUROLAB laboratory provides testing and compliance services within the scope of UNE 48254 standard. A well-known way of making reflective beacon areas is to coat the base with reflective paint and apply suitable glass beads to the surface while still in a soft and sticky state to create a layer of partially embedded bead.

This procedure requires two steps and requires care and skill to obtain an optically efficient, durable sign product. Paint coating should be applied in a correct thickness according to the size of the products. If a quick-drying paint is used, the coating film's viscosity and adhesion properties change rapidly as it dries, so it must be applied correctly for products to be securely bonded and properly positioned.

If a slower drying paint is used, the products may sink too much during the drying period and there will also be a delay in finishing the sign making process. In both cases, the products are applied to the surface of the wet or partially dried paint film. The surface properties and viscosity that changes during drying affect the nature of the dye bond and the capillary force, which determines the way the wet paint travels on the products and the resulting physical structure.
