WEATHERPRO™ SG HIGH PERFORMANCE ABS
WeatherPro SG is a rigid, UV-stable thermoplastic sheet. Combining a unique, proprietary UV-resistant surface with the ductility and high impact resistance of ABS, WeatherPro SG is ideal for thermoforming and fabrication into custom sign applications. Specifically designed for sign backs of irregular shapes, such as “cloud” signs, this product is listed in the Sign Components Manual as suitable for sign bodies.
CUTTING Cutting WeatherPro SG is best accomplished using blades designed for plastics. Plastic-cutting blades have a higher tooth count than standard wood-cutting blades, allowing for a smoother cut without having jagged edges. It also helps prevent kickback if you’re using an electric saw. Use a thicker blade so the plastic does not melt and stick back together. DRILLING High-Speed Steel (HSS) drill bits are best for plastics including WeatherPro SG. Black Oxide bits are somewhat more durable. CEMENTING Conventional solvent cements and polymerizable cements will readily join WeatherPro SG sheet to itself and other plastics. Polymerizable cements give higher joint strengths than solvents. Many commercial cements and adhesives are readily available from your plastics distributor. PRE-DRYING Generally, WeatherPro SG should not require pre-drying prior to forming, depending on age and storage conditions. As an ABS-based thermoplastic, it is hygroscopic and will absorb moisture over time. Keep WeatherPro SG wrapped and dry at all times to reduce moisture absorption in sheet. Store in a cool dry place.
FABRICATION SunGard sheet can be drilled, routed, sheared and painted using the same fabrication and machining techniques as for general purpose ABS. Most conventional mechanical fixing methods such as screws and rivets can be used, solvent bonding is common as is the use of many commercial adhesives. For proper mechanical fastening, always over-drill the hole by 1/16" to allow for expansion. Use an approved silicone sealant in the hole with the fastener to inhibit stress cracking at the hole. CLEANING To clean, wash with mild, non-abrasive soap or detergent and rinse with clean water and a dry, soft cloth. To prevent water spots, dry thoroughly with chamois or clean cloth or sponge. Do not use abrasive cleaners, cleaners based on aromatic hydrocarbons, or other harsh solvent-based cleaners. The following cleaning agents are compatible with WeatherPro SG surfaces when used according to the manufacturers’ recommendations: • Isopropanol (45% concentrations) • Most mild, non-abrasive liquid or powdered soaps and detergents • Mr. Clean™ • Top Job® • Joy™ • Cascade™
* Spartech cannot guarantee that its laboratory testing conditions will be duplicated in your actual end-use conditions. Therefore, these results should be used as a guide only, and it is recommended that the products be tested under actual end-use conditions by the user. When using these products, do not allow them to remain on the sign face longer than it takes to remove the dirt, grime, or other deposits. Immediately remove the cleaning agent with a soft clean cotton cloth.
