Features & Benefits
- Ready-to-Use Product Features
- Features & Benefits
- Excellent resistance to weathering including: UV radiation, extreme temperatures, as well as rain, ice and snow.
- Extends the useful life of the roof.
- PolyBrite 90.1 can reduce energy costs by decreasing roof surface temperature.
- Fungal and algal resistant – even in high temperatures.
- Benefits
- Polyglass offers all the product components needed for these systems – one stop shop
- A variety of systems which can be used on new construction or tear off and replace roofs
- Offers excellent resistance to extended exposure to solar ultraviolet energy
- Can decrease the roof surface temperature, thereby reducing energy costs
- Superior tensile strength for a strong roof
- Easy to install, no kettle, no torch and no special tools or equipment needed other than a heavy roller
- Much safer than traditional hot asphalt BUR or torch down systems
- Should reduce the cost of insurance for the roofing contractor
- Low VOC and odor - presents minimal hazard to the applicator or the environment
- Resistant to dirt pick-up – easy to maintain
- Fungal and algal resistant

- Cure Method
- Uses
- Recommended for use on various uncoated metal components that exhibit oxidation or “rusting”. Designed to prevent further exposure to environmental conditions that cause oxidation of the metal, commonly known as rust.
- Promotes adhesion of elastomeric coating applied to uncoated metal surface that exhibit signs of oxidation. Contact Polyglass Technical Services for clarification of unusual surfaces or project conditions.
- Application Instruction
Surface Preparation
Surfaces to be coated with PolyBrite 90.1 must be properly prepared. All surfaces must be clean dry and free of loose particles.
Application
- Stir well prior to application.
- PolyBrite 90.1 is recommended to be applied with high pressure sprayer for best appearance and coverage. It may also be applied by roller or brush applications.
- PolyBrite 90.1 can be applied in excess of 40 mils in a single coat without blistering, while maintaining maximum adhesion.
Application Equipment
This product may be sprayed, brushed, or rolled. Due to the high viscosity of the material, a high-pressure airless paint pump capable of producing 3500 PSI should be used. The pump should have a minimum of 3 gallons per minute output. Always use components rated for pump pressure. Hoses should be BUNA-N jacketed for prevention of moisture contamination. Hoses should have a minimum I.D. of 3⁄4" and an adequate working pressure. The spray gun should be high pressure (5000 PSI) with reverse-a-clean spray tip, having a minimum orifice of .030 and a 50° fan tip.
Do not use hose that has been used for Acrylics or other waterborne coatings as the liner absorbs moisture and initiates the silicone cure process.
Cleaning
- Clean equipment and overspray with water.
- Clean hands with waterless hand cleaner.
- Application tools and equipment can be cleaned with lukewarm water and soap, followed by a rinse of isopropanol, acetone, or Simple Green®. Recirculate through lines and gun until residual coating is removed.
- Do not use mineral spirits, xylene, toluene, or VMP & naptha solvents.
