The cathode-ray tube is a mainstay of our high-technology age. And such applications as computer-aided design or high-resolution business graphics demand CRTs providing high resolution and a crisp, sharp image. That's where KASIL® potassium silicates from PQ come to the aid of the CRT manufacturer. Potassium silicate is an ideal adhesive and settling agent for phosphors used in color and monochrome CRTs. Its adhesive properties bond the phosphor to the back of the glass. As a settling agent, it helps spread phosphors in a smooth, continuous layer. Minimized concen-

trations of magnetic materials allow the phosphors to retain their true colors. You can use our NYACOL® colloidal silicas for adherence—as antislip coatings on bags and cartons. With more surface friction, your packages can be stacked and handled without slipping and sliding. And the PQ® sodium silicates used as adhesives in the manufacture of paper tubes and cores, paperboard, and plywood are not only inexpensive, but impart rigidity to strengthen the products and help them hold their shape.
