Lord 7500
Two-component, High-Performance, Urethane Adhesive

Lord 7500 has been discontinued because Lord has been experiencing issues procuring a key ingredient.  Lord has suggested Lord 7100 and Lord 7150 as replacements to the impacted products.  They have verified, by laboratory testing, that the 7100 and 7150 meet or exceed the performance characteristics of Lord 7500.

Description
Lord^® 7500A/B and Lord 7500A/C are two-part, urethane adhesives used to bond a wide variety of plastics, metals and elastomers. Lord 7500A/B adhesive and Lord 7500A/C urethane adhesive cure at room temperature, or can be accelerated with heat.

Features and Benefits
Primerless Adhesion - reduces material and labor cost by eliminating the need to prime many difficult to bond plastics.

Contains No Solvent - safer for workers. Does not require expensive hood systems or explosion-proof equipment. Will not deplete the ozone.

Variable Cure - cures completely at room temperature or more rapidly with heat.

Impact Resistant - provides impact resistance at temperatures ranging from -34°C to 116°C (-30°F to 240°F).

Environmental Resistance - resists sunlight, weathering, humidity and salt spray.
 

Surface Preparation
Prior to bonding, parts should be clean, dry and free from oil contamination. Cleaning with an organic solvent is usually sufficient. Adhesion can be enhanced by mechanical abrasion of the surface, although it is not always required.

For bonding rubber, use Lord 7701 surface treatment on the rubber surface before joining. For bonding glass, use Lord 7715 primer.

Mixing
Lord 7500A resin should be mixed with Lord 7500B or 7500C at the proper mix ratio.

Lord 7500A/B adhesive offers a working time of approximately 20-30 minutes and handling strength in about 24 hours.

Lord 7500A/C adhesive offers a working time of approximately 6-10 minutes and handling strength in about one hour.
