Oatey HERPROPOXY4OZ Hercules Propoxy 20 Epoxy Putty 4 Oz Cartridge

Product Description

The Oatey HERPROPOXY4OZ is the Hercules ProPoxy 20 Epoxy Putty, a two-part hand-kneadable epoxy compound designed for fast, reliable repairs on a wide range of materials. This product comes in a 4 oz cartridge and is used by plumbers, pipefitters, HVAC technicians, maintenance professionals, and general contractors who need a strong, durable bond in demanding environments. The putty starts as two distinct components — one black, one white — and when kneaded together by hand, it initiates a chemical cure that creates a hard, solid repair mass. No mixing tools are required, making it a practical choice for field repairs where speed and simplicity matter. The ProPoxy 20 epoxy putty bonds to metal, masonry, wood, glass, ceramic, and plastic, giving tradespeople a single-product solution across multiple substrates. It is commonly used to seal pipe leaks, fill gaps in masonry, patch metal surfaces, and make structural repairs on plumbing and mechanical systems. The formulation is based on Bisphenol-A-(Epichlorhydrin) epoxy resin with a hardener component, and it contains crystalline silica in non-respirable form. The cured material is rated to withstand temperatures up to 300 degrees Fahrenheit, making it suitable for hot water lines and moderate-heat applications. With a specific gravity of 1.95 and a VOC content below 0.1 percent, this putty is a low-emission option appropriate for use in occupied or partially enclosed spaces. The net weight of the cartridge is 0.34 pounds. Tradespeople rely on this epoxy putty for emergency pipe repairs, patching corroded fittings, sealing cracks in concrete and masonry, and bonding dissimilar materials on job sites where downtime must be minimized.
