Metaguard 305 is a 70 micron monomeric calendered gloss overlaminate. The MG305 provides an increase in UV protection and longevity for the printed media. The MG305 is a perfect match to any of the medias in the Metamark MD3 range. The MG305 is a perfect laminate of interior or exterior applications. It can be applied over both flat and slightly – curved surfaces. The rule of thumb is the overlaminate must match or excess the life of the media.
