The laser can be used to "fire" or fuse our material to the surface of the glass. We call this a "positive" or "additive" mark. Positive marks on glass can be made in a variety of colors. Currently six different color marks can be achieved: black, bronze, blue, gray, yellow and green. A glass marking material which fires out clear is also available.
Our materials can be formulated to be applied by spraying, pad-printing, roll coating, screen printing or brushing. The material is applied to the substrate, dried and marked with the laser. After marking the excess material is removed by brushing or washing the surface. Lab tests have demonstrated that the marks are chemically resistant to several acids and bases and have survived a variety of abrasive tests.
A tape or labeling method of application is also available. However, at this time the only color available is black.
