URALANE® 5774-1 A/C

URALANE® 5774-1 A/C Polyurethane Adhesive is a two-component, self-extinguishing material that cures at room or elevated temperatures to form tough, impact-resistant bonds to thermoplastics or metal substrates. The mixed compound is a soft paste, making it suitable for application to vertical or overhead surfaces. Cure may be accelerated at moderate temperatures (150 - 200°F / 65 - 95°C) for faster production schedules. This product is available in dual-barrel cartridges for quick, convenient application. URALANE® 5774-1 A/C Polyurethane Adhesive is qualified to BMS 5-105, Type 5.

Processing Data

Mix both components thoroughly for 2-3 minutes to ensure complete blending. Mix only that amount which can be dispensed in 15 minutes at 77°F (25°C). Material temperatures should be above 18°C (65°F) when mixing. To extend work life spread mixed adhesive on a metal plate covered with polyethylene film immediately after mixing.

For faster cure, the fabricated part can be subjected to the following accelerated cure schedules after a 30 - 60 minute gelation at room temperature:

  • Option # 1: 2 - 4 hours at 150°F (66°C), or
  • Option # 2: 1 - 2 hours at 200°F (95°C)

For optimum performance of URALANE® 5774-1-A/C polyurethane adhesive, the recommended bond line thickness is 3-5 mils and the fabricated part should be clamped (or held stationary) for a minimum of 4 hours.

Storage & Handling

Storage Conditions

URALANE® 5774-1 A/C should be stored in a dry place, in the original sealed container at temperatures between 2°C and 40°C (35.6°F and 104°F). Tightly reseal containers after each use. Under these storage conditions, the product has a shelf-life of 6 months (from date of shipment). The product should not be exposed to direct sunlight. Do not refrigerate. These products are moisture sensitive and are packaged under a blanket of dry nitrogen. After opening a container, re-blanket with dry nitrogen and then tightly reseal.
