Product description:
LOCTITE UK 1351 B25 / 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 basedon isocyanates. By mixing both components in a weight ratio of 100 : 40, a hard elastic two-component structural adhesiveis formed through chemical reaction. The product can also be used for bridging wide gaps up to 15 mm. Moreover, the adhesive is not abrasive, since high-quality raw materials are used. In addition, the product group is outstanding for its low exothermic reaction while curing. Due to the use of natural raw materials (from different cultivation areas), a variation in color between different batches is possible.

Application Areas
LOCTITE UK 1351 B25 / LOCTITE UK 5452 is mainly used for the structural bonding of fibrous composite materials, e.g. in the wind energy or shipbuilding industry. Further information about the product: biuro@woronko-kleje.pl

Steps to achieve the best adhesive results:
Pretreatment
The substrate should be clean, dry, free of dust, oil, grease and other contaminants. The usage of suitable primers on metal surfaces can improve the adhesion and/or the long-term bond stability. The surface of plastic materials should be cleaned, so as to remove any kind of release agents present on the substrate surface. An improvement of the adhesion can be achieved by grinding or sandblasting the surface.

Application
LOCTITE UK 1351 B25 / LOCTITE UK 5452 is processed from a side-by-side cartridge using commercially available compressed-air guns. Since the material is thixotropic, it is advisable to use geared compressed-air guns. The two components are mixed with a static mixer, e.g. spiral mixers with no less than 24 mixing elements. Striation must not be visible. The first and the last 10 cm of material mixed and dispensed with a static mixer need to be disposed of (do only use thoroughly mixed material, consider the color of the mixture). In case of manual mixing, the thixotropic formulation of resin/hardener involves high risk to the quality, such as the inclusion of air.
