JB WELD RADIATOR REPAIR KIT - JB2120

The JB Weld Radiator Repair Kit 2120 is a specialty repair kit for restoring leaking radiators and plastic tanks on automotive and other equipment. The kit uses a two-part epoxy system supplied as RadiatorWeld Part A resin and Part B hardener, supported by a 28 g epoxy adhesive and a 5 cm x 15 cm fibreglass reinforcing cloth, plus sandpaper and an applicator. Once mixed and cured, the epoxy is chemical resistant and withstands temperatures up to 250�F, repairing cracks up to 4 inches long and holes up to 1/4 to 3/8 inch in diameter. The formulation is suitable for radiators and tanks made from aluminium, copper-brass, most plastics and other metals, but is not recommended for polyethylene or polypropylene. The kit sets in around 5 minutes and cures in approximately 4 hours, allowing on-vehicle repairs without removing the radiator or tank. It is commonly used on radiators, washer fluid tanks, storage tanks and water tanks where a permanent or temporary repair is required.
