3M™ Scotch-Weld™ DP8810NS Acrylic Structural Adhesive

3M Scotch-Weld DP8810NS Acrylic Adhesive: Low-odor two-part structural adhesive

The 3M Scotch-Weld DP8810NS is a two-part structural acrylic adhesive designed to bond difficult materials without complex surface preparation.

Its low-odor formula makes it suitable for use in workshops without heavy-duty ventilation, a real advantage for daily work.

It provides high mechanical strength on metals, composites, and plastics, with excellent resistance to impact and vibration.

Presentation of the 3M Scotch-Weld DP8810NS acrylic adhesive

The 3M Scotch-Weld DP8810NS is a two-part structural acrylic adhesive designed for high-performance bonding. Its "NS" (No Smell) formulation gives it a low odor, a concrete advantage in workshops or confined spaces.

It comes in a dual-component cartridge with a 1:1 mix ratio. Application is performed using a standard applicator gun with a static mixing nozzle.

Composition and two-part acrylic technology

A two-part acrylic adhesive relies on the chemical reaction between a resin and a hardener. As soon as it is mixed, polymerization begins and produces a rigid bond that is resistant to impacts and vibrations.

3M's acrylic technology allows for the bonding of minimally or unprepared substrates: slightly oily metals, plastics, and composites. No primer is needed in most cases.

The DP8810NS develops high shear strength on steel, aluminum, ABS, polycarbonate, or fiberglass. It is a common choice in the automotive, industrial, and construction sectors.

Technical properties and mechanical performance

The 3M Scotch-Weld DP8810NS is a two-part structural acrylic adhesive with a 1:1 mix ratio. It cures at room temperature without applying heat.

Its low-odor (NS = No Smell) formulation sets it apart from classic structural acrylics, which are often very pungent. A concrete asset for poorly ventilated workshops.

The DP8810NS offers excellent mechanical resistance once polymerized:

• Shear strength: up to ~20 MPa on steel
• Peel strength: high, suitable for assemblies subjected to vibrations
• Impact resistance: good toughness due to the flexibility of the polymerized bond
• Temperature resistance: from -40°C to +120°C continuously

Its open time of approximately 8 to 10 minutes allows time to position parts before setting. Handling strength is reached in 20 to 30 minutes at 23°C.

Product	Type	Open time	Shear strength	Special feature
3M DP8810NS	1:1 Acrylic	~10 min	~20 MPa	Low odor
3M DP8805NS	1:1 Acrylic	~5 min	~18 MPa	Faster setting, low odor
3M DP8825NS	1:1 Acrylic	~25 min	~20 MPa	Long open time, low odor
Loctite EA 9466	1:1 Epoxy	~90 min	~25 MPa	High strength, slow setting

Compatible materials and areas of application

The 3M Scotch-Weld DP8810NS is designed to bond a wide range of materials, including substrates that are difficult to assemble with classic adhesives.

It adheres effectively to plastics (ABS, polycarbonate, polyester, PVC), metals (steel, aluminum, stainless steel), composites, and painted or coated materials.

Its acrylic formulation allows it to function on slightly oily or poorly prepared surfaces, where an epoxy glue would require rigorous stripping.

Typical usage areas:

• Assembly of automotive and transport parts (panels, reinforcements, trim)
• Manufacturing of industrial machinery and equipment
• Construction of caravans, recreational vehicles, and car bodies
• Assembly of composite panels and lightweight structures
• Applications in electronics and appliances requiring low odor in the workshop

The "NS" (No Smell) designation is particularly useful in poorly ventilated environments: closed workshops, indoor production lines, sensitive areas.

This product is not suitable for polyethylene (PE), untreated polypropylene (PP), or PTFE, substrates which require a specific adhesion primer or a dedicated adhesive.

Comparison: 3M Scotch-Weld DP8810NS vs. other structural acrylic adhesives

The market for two-part structural acrylic adhesives is dense. Here is how the DP8810NS positions itself against its main competitors.

Product	Manufacturer	Mix ratio	Assembly time	Shear strength	Low odor	Strengths
Scotch-Weld DP8810NS	3M	10:1	~10 min	≈ 17 MPa (steel)	✔ Yes (NS)	Low odor, good flexibility, multi-material adhesion
Scotch-Weld DP8805NS	3M	10:1	~5 min	≈ 15 MPa (steel)	✔ Yes (NS)	Faster setting, ideal for high production rates
Scotch-Weld DP8825NS	3M	10:1	~25 min	≈ 18 MPa (steel)	✔ Yes (NS)	Long assembly time, large surfaces
Araldite 2021	Huntsman	1:1	~25 min	≈ 14 MPa (steel)	✘ No	Versatile, good chemical resistance
Plexus MA310	ITW	10:1	~18 min	≈ 20 MPa (steel)	✘ No	Very high strength, composites and metals

The DP8810NS offers a good balance between working time and mechanical strength. It is neither the fastest nor the strongest, but it combines low odor, flexibility, and multi-substrate compatibility.

Against the Araldite 2021, it wins on workshop odor management, a decisive criterion for poorly ventilated environments.

Against the Plexus MA310, it yields in raw strength, but remains more pleasant to implement on a daily basis.

Within the 3M range, the choice is mainly based on the assembly time: DP8805NS for speed, DP8810NS for standard use, DP8825NS for complex bonding or large surfaces.

Implementation tips and precautions for use

Surface preparation and application conditions

Good preparation is the key to a structurally reliable bond. Surfaces must be clean, dry, and degreased before any application.

Remove oils, dust, and residues with a suitable solvent (isopropanol or MEK). On metals, light sanding improves adhesion.

The ideal application temperature is between 18°C and 25°C. Below 15°C, polymerization slows significantly and final strength may be compromised.

• Systematically degrease with a lint-free cloth
• Sand smooth surfaces (aluminum, stainless steel, technical plastics)
• Use a 3M adhesion primer on difficult substrates (PP, PE)
• Allow the solvent to dry before applying the glue

The DP8810NS is applied with a manual or pneumatic applicator gun equipped with a static mixing nozzle. Never apply without a nozzle: the two components must be mixed in an exact proportion.

Purge the first doses before application on the part. The open time is approximately 4 to 6 minutes at 23°C: assemble quickly and keep the parts in position during initial setting.

Wear nitrile gloves and work in a ventilated space. Although the DP8810NS is formulated with low odor, the standard precautions associated with two-part acrylic adhesives remain mandatory.

FAQ - 3M Scotch-Weld DP8810NS Acrylic Adhesive

1. What is the difference between the DP8810NS and other 3M acrylic glues like the DP8005?

The DP8810NS is formulated to offer low odor (NS = No Smell), making it suitable for poorly ventilated environments or closed workshops.

The DP8005 releases more pronounced vapors but offers slightly different chemical resistance. The choice mainly depends on your working conditions.

2. On which materials can the DP8810NS be used?

It adheres to a wide range of substrates: metals (steel, aluminum), technical plastics (ABS, polycarbonate, polyester), composites, and painted materials.

It is particularly effective on multi-material assemblies where conventional welding is impossible.

3. What is the handling time after application?

The handling time is approximately 4 to 6 minutes at 23°C. Full strength is reached after 24 hours of polymerization.

Below 15°C, these times increase significantly. Plan accordingly in your production process.

4. Must surfaces be prepared before bonding?

Yes. Thorough degreasing is essential to guarantee mechanical performance. Use a suitable solvent (isopropanol, acetone) and let it dry before applying the glue.

On some low-surface-energy plastics, a primer or plasma treatment may be necessary.

5. Does the DP8810NS resist impacts and vibrations?

Yes, that is one of its strengths. The DP8810NS is a structural adhesive designed to absorb dynamic stresses, impacts, and vibrations.

It is therefore well-suited for industrial applications subject to repeated mechanical stress, such as the assembly of panels or lightweight structures.

6. Can it be applied with a standard gun?

The DP8810NS is used with a 3M applicator gun compatible with two-part cartridges (1:1 ratio), equipped with a static mixing nozzle.

The mixing nozzle is essential: it ensures the homogeneous mixing of the two components and directly determines the quality of the bond.
