This paper will describe the formulation and properties of silicone based coatings for spandrel and decorative application. Two different silicone systems will be discussed:
• The OC500 coating is based on 100% silicone resin and utilizes addition reaction for crossliking. This coating has shown outstanding adhesion to sputter coated, float and pyrolitic glass substrates and passed 5000 hours of QUV without any visiblegloss or film defects as per ASTM C1142. In addition, it shows no defect after ten days in boiling water.
• The Deco Vas coating is based on hybrid silicone resin and utilizes moisture cure system. This coating has shown outstanding adhesion to sputter coated, float (air and Sn side) glass substrates. Fully cured coating is scratches and weathering resistant.
Both coatings are 100% green with zero VOC and can be applied by roll coat or screen print. The coatings can be formulated with any colors including metallic.
The chemistry, physical properties and applications of this coating will be discussed in detail at the presentation.
There looks to be some fantastic topics at the symposium this year, several from ICD will be in attendance yet not me. I hope they bring me back a Mojito or some ceviche.
