Ultra-High-Solid-platform technologies VOC-compatible coating – with significantly reduced solvent consumption.

Ultra-High-Solidplatform technologies The steadily growing requirements placed on surface coatings and the continuous reduction of the total VOC content in paints and coatings led FreiLacke to develop Ultra-High-Solid systems or UHS for short. In the field of conventional coatings, completely new coating systems with a solids content of up to 80 percent by weight and a VOC value < 350 g/l were developed and brought to series-production readiness for this purpose. The new UHS systems also include two primers and a high-gloss top coat.

Polyurethane primer with quick recoatability Epoxy primer for high corrosion protection Coating systems with solids content of up to 80 percent by weight As a classic 2C polyurethane primer, UR1937H can be used wherever rapid recoatability with a variety of top coat systems is required. UR1937H stands out thanks to its high stability and fast drying. Despite its high solids content of approx. 80 percent by weight, application by means of conventional air atomisation or air-assisted processes meets today's requirements. The advantages of UR1937H in combination with the likewise recently...

Technical data High-gloss polyurethane top coat system A direct comparison of the properties of the products By using the latest generation of raw materials, it was possible to achieve outstanding characteristics in terms of surface qualities and UV and chemical resistance. As the matching top coat system for UHS primers UR1937H and ER1936H, this structure offers the solution to a wide variety of requirements in many areas: reduction of emissions, short cycle times and balanced application and surface properties. High-gloss 2C Ultra-High-Solid polyurethane top coat platform technology...
