Technical Data Sheet LOCTITE® 7387 July-2004 PRODUCT DESCRIPTION LOCTITE® 7387 provides the following product characteristics: Technology Activator for Loctite toughened acrylic adhesives Chemical Type Substituted dihydropyridine Solvent n-Heptane and Isopropanol Appearance Transparent yellow to light amber liquidLMS Viscosity Very low Cure Not applicable Application Cure promotion of toughened acrylic adhesives LOCTITE® 7387 is designed to initiate the cure of Loctite toughened acrylic adhesives. TYPICAL PROPERTIES Specific Gravity @ 25 °C Viscosity @ 25°C, mPa·s (cP) Flash Point - See MSDS 0.80 1 to 2 TYPICAL PERFORMANCE Fixture time and cure speed achieved as a result of using LOCTITE® 7387 depend on the adhesive used, the substrate bonded, surface cleanliness and whether one or two surface activation is used. Fixture Time, ISO 4587, minutes: Steel (grit blasted) and Loctite® Adhesive 330, single side activation ≤4LMS (Fixture time is defined as the time to develop a shear strength of 0.1 N/mm²) HANDLING PRECAUTIONS Activator must be handled in a manner applicable to highly flammable materials and in compliance with relevant local regulations. The solvent can affect certain plastics or coatings. It is recommended to check all surfaces for compatibility before use. GENERAL INFORMATION This product is not recommended for use in pure oxygen and/or oxygen rich systems and should not be selected with a sealant for chlorine or other strong oxidizing materials. For safe handling information on this product, consult the Material Safety Data Sheet (MSDS). Under no circumstances should activator and adhesive be mixed directly as liquids. Use only in a well ventilated area. Where aqueous washing systems are used to clean the surfaces before bonding, it is important to check for compatibility of the washing solution with the adhesive. In some cases these aqueous washes can affect the cure and performance of the adhesive. Directions for use 1. Most surfaces may be bonded "as received" but contamination such as loose oxide layers or excessive oil may affect cure speed and bond strength. Cleaning is recommended if maximum strength is required. 2. Brush on the activator to one of the mating surfaces to be bonded. Apply adhesive to other surface. 3. For large gaps (>0.40 mm) or where maximum cure speed is required then treatment of both surfaces is recommended. 4. The activator will not dry and will remain active for up to 6 hours. Bond assembly should be completed within this time. 5. Where adhesive is applied onto an activated surface, assembly should be completed as quickly as possible (within 15 seconds). 6. Secure the assembly and await fixturing before any further handling. Loctite Material SpecificationLMS LMS dated July-08, 2004. Test reports for each batch are available for the indicated properties.
