LOCTITE UK 1366 B10 / LOCTITE UK 5452 is a solvent-free, two-component structural adhesive based on polyurethane. The resin part (component A) contains organic compounds with hydroxyl groups, the hardener (component B) is based on isocyanates. By mixing both components in a weight ratio of 4.7 : 1, a hard elastic two-component structural adhesive is formed through chemical reaction. After curing the product does not show any measurable change in volume. Due to the use of natural raw materials (depending on cultivation areas), a variation in color between different batches is possible.
