Description

LOCTITE UK 8103 B30 / LOCTITE UK 5400 is a solvent-free two-component 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 mix ratio of 5 : 1 a hard elastic adhesive is formed through chemical reaction. After curing the product exhibits no measurable change in volume. As natural raw materials (from different cultivation areas) are used a variation in colour between different batches is possible.

APPLICATION AREAS LOCTITE UK 8103 B30 / LOCTITE UK 5400 is used for bonding of pre-treated metals, synthetic materials, wood and hard foams. The main application is the production of sandwich elements, e.g. for vehicle, container and the construction industry. Furthermore this product is used as a potting, filling and coating compound.

DIRECTIONS FOR USE Preliminary Statement: Prior to use it is necessary to read the Material Safety Data Sheet for information about precautionary measures and safety recommendations. Also, for chemical products exempt from compulsory labelling, the relevant precautions should always be observed. Please also refer to the local safety instructions and contact Henkel for analytical support.

Pre-treatment: 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

Curing: LOCTITE UK 8103 B30 / LOCTITE UK 5400 can be cured at room temperature above 15°C and elevated temperatures (up to 60°C). The curing time can be reduced by increasing the temperature or the addition of the accelerator Loctite UK 6100, with the simultaneous reduction of processing time (i.e. pot life, open time) to be observed. While curing there should be adequate contact pressure (load pile, presses, clamps) and fixture hold the joint in place. An adhesive squeeze out along the bond line is a good indication of sufficient adhesive in the joints.

Cleaning: Fresh, uncured material (cleaning application equipment, substrate contamination etc.) can be removed with LOCTITE SF 8040; cured adhesive can only be removed mechanically.
