Lord 810/20 Low Read-Through (LRT) Acrylic Adhesive

Lord 810/20
This is a hazardous material, shipping restrictions and surcharges may apply.

LORD® 810 Low Read-Through (LRT) acrylic adhesive when cured with LORD Accelerator 20 creates a flexible adhesive system for bonding metals, such as aluminum, galvanized steel and CRS, and engineered plastics, such as PC-ABS and ASA. LORD 810 adhesive in combination with LORD Accelerator 20 delivers fast cure speed and strong bonding with minimal bondline read-through (BLRT).

LORD Accelerator 20 allows precise control of the adhesive bondline thickness due to its content of glass beads. For further detailed information, refer to the LORD Accelerator 20 data sheet.

Shelf Life

Shelf life is six months when stored below 77°F (25°C) in original, unopened container. Storage temperatures of 40-60°F (4-15°C) are recommended. If stored cold, allow product to return to room temperature before using. Protect from exposure to ultraviolet light.

LORD 810 adhesive is flammable. Do not store or use near heat, sparks or open flame.

Features and Benefits

• Aesthetics – bonds thin and flexible substrates with little to no bondline read-through.
• Convenient – requires little or no substrate preparation for bonding metals and plastics.
• Non-Sag – remains in position when applied on vertical or overhead surfaces, allowing for greater process flexibility.
