When using a Duo-Pak (DP) size adhesive, rely on 3M dispensing equipment for convenient and accurate metering, mixing and dispensing. Self-Leveling and Rapid-Setting AdhesiveOur 3M™ Scotch-Weld™ Urethane Adhesive DP601 is a two-component polyurethane that is formulated to be rapid-setting, providing fast, strong bonds. This urethane adhesive has a 1:1 mix ratio and sets in approximately 4 minutes, with full cure in 1 hour. It is self-leveling and delivers a clean and smooth final result. 3M™ Scotch-Weld™ Urethane Adhesive DP601 is tough and non-brittle for long-term durability. This product is capable of bonding dissimilar substrates, such as some plastics, concrete, wood and metal. Recommended ApplicationsBonding of plastic to concrete, metal or woodBumper repairBonding reflectors to concrete or asphalt Dispenses Duo-Pak Cartridge SystemOur 3M™ Scotch-Weld™ Urethane Adhesive DP601 is a two-part component system. Our Duo-Pak cartridge keeps the components separate until ready for mixing to maximize working time. With the squeeze of a trigger the components are automatically mixed with our innovative mixing nozzle and easily dispensed precisely where needed without an unwanted mess. The bubble-free liquid begins curing immediately while also self-leveling to create a tough, non-brittle bond. Our fast curing formula provides a one minute work life. Understanding Urethane AdhesivesTwo part urethane adhesives cure chemically, rather than relying on moisture from the air. Because of this, they can cure quickly with no depth of cure issues in contrast to one-part urethane adhesive sealants. Urethane adhesives will bond most common materials such as wood, metals, rubbers, leather, tile and glass, many plastics, concrete and more. The versatility of urethane adhesives is exhibited in the different formulations that have varying cured properties such as different levels of stiffness or flexibility, open time and cure speed, and hardness. They can cure to a relatively rigid or highly flexible state to meet a wide range of requirements. In either finished state, urethane adhesives will maintain bond strength integrity through variable environmental factors such as temperature, moisture and chemical exposure.
