Overview

LOCTITE UR 7225 is a solvent-free, moisture curing one component adhesive based on polyurethane. At room temperature and the required humidity in the joint sufficient strength will be obtained after approximately 50 to 70 minutes. For faster curing LOCTITE UR 7225 can be cured in a heated press. Maximum temperature must not exceed 70°C.

APPLICATION AREAS LOCTITE UR 7225 is used for the manufacture of sandwich elements with porous substrates (e.g. wood) which contain humidity. The substrates can be bonded to one another or to metals, laminated panels, various plastics, rigid foams made of polystyrene, polyurethane and others.

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.

Application: Application Temperature : 10 to 35 °C.

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

Storage: When properly stored in a cool, dry location, with the container tightly closed when not in use, this product will have a shelf life of at least 9 months. Recommended Storage: 15°C to 25°C. Storage below 10°C or greater than 50°C can adversely affect product properties. LOCTITE UR 7225 is frost-sensitive.
