Spabond 445 is a high performance, hardened adhesive system ideal for bonding large structures where substrate surfaces have irregular geometry. Developed from the proven performance of its predecessors while sharing the same hardener components as Spabond 435 and 440 to offer a complete adhesive system.
The product has a thick, pasty consistency, and can be applied without sag in thicknesses greater than 30mm at 15°C, making it ideal where large irregular vertical glue lines are required. Available with a choice of two hardeners, the improved progression cure chemistry eliminates the need for an extra slow hardener.
The exclusive formulation offers greater safety and hygiene thanks to the careful selection of low-toxicity raw materials.
The product has a mix ratio of 3:1 by volume. To facilitate mixing, the hardener components are pigmented to visually indicate the quality of the mix. A black resin option is also available, useful for enhancing the aesthetic appearance of exposed carbon composite seam lines.
Spabond 445 is available in cartridges and straight-sided pails and drums for machine mixing/dispensing.
