The 3M™ Scotch-Weld™ Acrylic Adhesive DP820 is a two-part, toughened acrylic structural adhesive designed for high-performance bonding across various substrates. Its formulation offers excellent shear and peel strength, making it suitable for demanding industrial applications.

Strong Bonding with Minimal Surface Preparation: Effectively bonds metals (including oily metals), plastics, composites, and wood without the need for special surface treatments like chemical etching or priming.

Fast Cure Time: Offers a 15–20 minute work life, allowing for quick adjustments, and reaches handling strength in approximately 40 minutes. Full cure is achieved in 24–48 hours at room temperature. 

High Strength and Durability: Provides excellent shear and peel strengths along with good impact resistance, ensuring durable bonds. 

Medium Viscosity: Allows for controlled dispensing, reducing mess and improving application precision.

Metalworking: Suitable for HVAC systems, appliances, sporting goods, and specialty vehicles.

Sign Manufacturing: Ideal for panel-to-frame bonding, trim attachment, letter bonding, and frame assembly.

Plastic and Composite Bonding: Effective for bonding plastics, composites, and powder-coated metals.

General Industrial Use: Applicable in various industries requiring strong, durable bonds.
