Product Description
Overview
LORD® 7545-A/D Urethane Adhesive is a two-component, equal-mix urethane adhesive system designed for bonding FRP, SMC, primed metals, and other plastics with minimal surface preparation. The adhesive system is formulated to bond dissimilar substrates while providing high strength and durable structural performance. The 7545 system is available with multiple curatives to accommodate different process requirements, with the 7545-A/D combination offering an intermediate working time.
Key Features
- Two-component 1:1 mix urethane adhesive system.
- High-strength, durable structural bonding performance.
- Bonds FRP, SMC, primed metals and various dissimilar substrates with minimal surface preparation.
- Non-sag formulation for vertical and overhead applications.
- Resists weathering, humidity, salt spray and solvents after cure.
Suitable For
