Spandrel Glass - OPACI-COAT 300 from ICD

We at PRL Glass Systems are always improving our product lines to offer you the best and most up to date innovations in the glass industry including Spandrel Glass. Thanks to the advanced technologies of today and the known affinity of silicone to glass there is now an economic, water-based elastomeric coating that provides the optimum in glass opacification - OPACI-COAT-300®

Possible On Any Glass

This spandrel process allows the choice of any type of flat, bent or block glass. Since OPACI-COAT-300® is applied without heat at the final stage of the glass spandrel fabrication process it can be used with equal effectiveness on annealed, heat-strengthened, fully tempered, clear or high performance reflective products. Tinted or reflective glass colors can be harmonized or matched to eliminate any "banding" effect even on high visible transmission glass.

Opaci-coat 300 is a water base silicone rolled coated glass coating product that is supplied as flowable, thixotropic emulsion. Upon evaporation of water, the applied coating will cure to a tack-free silicone elastomeric film which provides opacification in any color to glass and related construction materials.

For your convenience, we also offer free color matching on virtually any color. We can also use your color sample as a reference to achieve your ideal color. OPACI-COAT-300® gives us unlimited colors your coated glass may be specified in most any color found on a color chip, no matter how bright or vivid. An average project can become an architectural masterpiece
