3M™ Scotch-Weld™ Urethane Adhesive 604NS, Black, Part A, 55 Gallon (50 Gallon Net), Drum

When using a Duo-Pak (DP) size adhesive, rely on 3M dispensing equipment for convenient and accurate metering, mixing and dispensing.

Fast-Curing Adhesive Delivers Tough Bonds Quickly

As a non-sag, two-component polyurethane adhesive, 3M™ Scotch-Weld™ Urethane Adhesive DP604NS is fast-curing. This adhesive quickly establishes tough bonds and offers low-temperature flexibility. 3M™ Scotch-Weld™ Urethane Adhesive DP604NS dispenses as a non-sag paste for accurate and precise handling during application. This adhesive can be used for bonding dissimilar substrates, such as concrete, ceramic, wood, plastic, rubber and metal. With a 1:1 mix ratio, this urethane adhesive has a 4-minute work life, reaches handing strength in 20 minutes and full cure in 6 hours.

Recommended Applications

Bonding wood or metal door sills to concrete
Bonding wood, metal or composite door frames to wood or other surfaces
Bonding wood paneling to wood or plaster
Staking electronic components
Covering material against corrosion
Sealing fabric water hoses
Encapsulating for tamper proofing

Understanding Urethane Adhesives

Two 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.
