Accurate metering and mixing of raw materials are crucial to the quality of the adhesive. Typically, raw materials are measured and pumped into a mixing vessel.
The mixing vessel combines the raw materials under controlled conditions, including temperature and pressure. This process initiates the chemical reaction that forms the polyurethane adhesive.
The mixture is transferred to the reactor kettle, where the chemical reaction continues to take place. The reaction conditions, such as temperature and dwell time, are closely monitored to achieve the desired adhesive properties.
During this phase, the polyurethane adhesive undergoes polymerization, leading to the formation of a viscous liquid.
After the reaction in the reactor, the adhesive may undergo additional processing steps to optimize its properties. These may include heating or cooling to control viscosity or enhance curing.
Polyurethane adhesives offer a good blend of cohesive strength and flexibility which makes them very tough, durable adhesives.
Polyurethanes bond well to most unconditioned substrates but may require the use of solvent-based primers to achieve high bond strengths. They offer good toughness at low temperatures, but typically degrade in strength after long-term exposure over 302 °F (150°C). They cure to form thermoset polymers with good solvent and chemical resistance. They are extremely versatile and can range in cured form from extremely soft elastomers to rigid, extremely hard plastics, depending upon the ration of hard and soft segments in the resin.
Advantages of polyurethane adhesives:
extremely tough;
good resistance to solvents;
high cohesive strength;
good impact resistance;
good abrasion resistance.
