Sylmasta WearShield Rapid is a high-performance, impact-resistant epoxy paste specifically formulated for maintenance professionals who need reliable and fast repairs in demanding environments. This advanced two-part epoxy system is heavily filled with alumina beads, delivering superior wear, abrasion, and impact resistance. The alumina reinforcement ensures that repaired surfaces are protected against the harshest conditions, including heavy mechanical impact, abrasive wear, corrosion, and chemical exposure.
Engineered for industrial applications, WearShield Rapid is ideal for repairing and protecting equipment in mining, power generation, and manufacturing environments. It is particularly effective for refurbishing ash handling systems, scrubbers, silos, chutes, mills, and metal castings that are subject to constant wear and impact. The tough, long-lasting alumina-reinforced layer not only restores structural integrity but also extends the service life of valuable machinery.
One of the key advantages of WearShield Rapid is its short working and cure times. The epoxy achieves a functional cure in just 45 minutes and reaches full strength within three hours. This rapid curing process minimizes equipment downtime, allowing maintenance teams to get machinery back into service quickly.
WearShield Rapid’s thixotropic formula prevents sagging, making it an excellent choice for vertical and overhead applications. This characteristic ensures that the epoxy stays in place during curing, even when applied to non-horizontal surfaces. The lightweight, smooth consistency of the paste also makes it easier to mix and apply compared to heavier, more rigid epoxy compounds.
Maintenance professionals will appreciate the versatility of WearShield Rapid, as it bonds well to a variety of substrates, including metal, wood, and most plastics. Whether addressing emergency breakdowns or conducting scheduled maintenance, this epoxy paste provides a reliable and long-lasting solution to impact and abrasion challenges.
