LORD® 661 Acrylic Adhesive Where To Buy


Product Information

LORD® 661 acrylic adhesive when cured with LORD Accelerator 6 creates an adhesive system that will bond composites including DCPD (dicyclopentadiene) resin and modified DCPD resin based FRP (fiber reinforced plastic). This adhesive system can also cross-bond composites to many metals.

LORD 661 acrylic adhesive in combination with LORD Accelerator 6 utilizes unique patented technology to create exceptionally strong bonds with excellent surface cure and minimal surface preparation.

Shelf Life

Shelf life is six months from date of shipment when stored at temperatures under 80°F (27°C) in original, unopened container. Storage temperatures of 40-50°F (4-10°C) are recommended. If stored cold, allow product to return to room temperature before using. Protect from exposure to direct sunlight.

LORD 661 acrylic adhesive is flammable. Do not store or use near heat, sparks or open flame.

Features and Benefits

Versatile – bonds difficult-to-bond composites, such as DCPD based FRP, and a wide range of metals with minimal surface preparation.

Environmentally Resistant – resists dilute acids, alkalis, solvents, water immersion, moisture and weathering.

Gap Filling Capability – fills gaps as large as 1.0 inch (25.4 mm).

Non-Sag – remains in position when applied on vertical or overhead surfaces, allowing for greater process flexibility.
