A versatile, VOC-free aluminum preparation that can be formulated into both waterborne and solventborne inks and coatings is introduced. The pigments in the preparations are chemically passivated to protect against moisture-triggered corrosion. Minimum explosion energy and gassing data, as well as formulation and performance data, are presented for both water- and solvent-based systems.
MetaShield LLC has launched MetaShield400TM. This fully transparent coating blocks UV wavelengths up to 400 nm, including both UV-A and UV-B rays.
