H.B. Fuller 45036/56666

H.B. Fuller 45036/56666 (DOUBLE/BUBBLE® D-85) urethane blue is a rigid, two-component, extra-fast-setting polyurethane structural adhesive. It displays an excellent combination of shear and peel strength with good impact resistance. It is highly recommended for bonding engineering thermoplastics, SMC, laminated surfaces, and the repair of reaction injection-molded parts. H.B. Fuller 45036/56666 is recommended for substrates such as metal, carbon steel, stainless steel, aluminum, tin, plastic, epoxy, polyester, phenolic, urethane, stone, glass, ceramic, and leather. This product can be used to repair urethane parts and is recommended for the repair of rubber hoses and flexible electrical connections. H.B. Fuller 45036/56666 is available in the unique DOUBLE/BUBBLE® job-sized package as Reorder No. 04023.

General Instructions

The individual components containing fillers should be stirred or agitated without introducing excessive air before use to ensure that all fillers are properly dispersed. To obtain the best cured properties, accurate proportioning and thorough mixing are essential. The production of the desired polyurethane requires accurate measurement of the two components and adequate mixing. In general, hand-mixing small production runs is easily accomplished by weighing the two components. Machine mixing utilizes the volumetric ratio. Most machines are calibrated by weighing the components and adjusting the volume ratio. Larger volume hand mixing is easily controlled by filling pre-measured buckets to the indicated heights. When using meter-mixed dispense equipment (MMD) machines, reservoir should be blanketed with nitrogen or dry air to avoid moisture and other contamination. Avoid contamination with oxidized metals (such as copper, brass, or mild steel), and rust or other metal oxides. The stability of the product is greatly reduced by materials such as strong acids or bases, sulfur compounds, amines, or reducing agents of any type. Surfaces to be bonded must be clean, dry and free from grease, oil, wax, weak oxide films and other contaminants.

Storage Conditions

These materials should be stored in a dry environment within a moderate temperature range. Extended exposure to temperatures above 35°C begins to degrade resin. Keep materials dry and free of moisture. Avoid exposing either component to moisture. Purge the container with dry air before closing to maintain the storage life. When using meter-mixed dispense equipment (MMD) machines, reservoir should be blanketed with nitrogen or dry air to avoid moisture and other contamination. Avoid contamination with oxidized metals (such as copper, brass, or mild steel), and rust or other metal oxides. The stability of the product is greatly reduced by materials such as strong acids or bases, sulfur compounds, amines, or reducing agents of any type.
