Scotch-Weld™ Structural Plastic Adhesives
DP8010 Blue • DP8010NS Blue
Technical Data Sheet
Product Description
October 2018
3MTM Scotch-Weld™ Structural Plastic Adhesive DP8010 Blue and DP8010NS Blue are
two-part, acrylic-based adhesives (10:1 ratio by volume) that can bond many low surface
energy plastics, including many grades of Polypropylene, Polyethylene and TPO’s
without special surface preparation.
These adhesives can replace screws, rivets, plastic welding, and two-step processes
which include chemical etchants, priming or surface treatments in many applications.
• Ability to structurally bond polyolefins
without special surface preparation
• Regular and Non-Sag Formulations
• Excellent water and humidity resistance
• One step process; no pre-treatment of
polyolefin substrates necessary
• Convenient hand-held applicator

Maximum time that adhesive can remain in a static mixing nozzle and still be expelled without undue force on the applicator.
Maximum time allowed after applying adhesive to one substrate before bond must be closed and fixed in place.
An open bead line will show some skinning in approximately 3 minutes. It is possible to bond parts with good strength if the parts
are made within 10 minutes. Therefore, the adhesive has a 10 minute open time for making bonds.
Minimum time required to achieve 50 psi of overlap shear strength, measured on HDPE
Note: The data in this sheet were generated using the 3M™ EPX Applicator System equipped with an EPX static mixer,
according to manufacturer’s directions. Thorough hand-mixing will afford comparable results.

Directions
For Use
1.
To obtain the highest strength structural bonds, paint, oxide films, oils, dust, mold release
agents, and all other surface contaminants must be completely removed. The amount of
surface preparation depends on the required bond strength and environmental aging
resistance desired by user. For suggested surface preparations on common substrates, see
the section on surface preparation.
2. Mixing
For Duo-Pak Cartridges
Store cartridges with cap end up to allow any air bubbles to rise towards the tip. To use,
simply insert the cartridge into the EPX applicator and start the plunger into the cylinders
using light pressure on the trigger. Then remove the cap and expel a small amount of
adhesive to ensure material flows freely from both sides of cartridge. For automatic mixing,
attach an EPX mixing nozzle to the cartridge and begin dispensing the adhesive. For hand
mixing, expel the desired amount of adhesive and mix thoroughly. Mix approximately 15
seconds after obtaining a uniform color.

6.
Mix thoroughly by weight or volume in the proportion specified on the product label or in
the typical uncured properties section. Mix approximately 15 seconds after obtaining a
uniform color.
Apply adhesive and join surfaces within the open time listed for the specific product.
Larger quantities and/or higher temperatures will reduce this working time.
Allow adhesive to cure at 60°F (16°C) or above until completely firm. Applying heat up to
150°F (66°C) will increase cure speed.
Keep parts from moving during cure. Apply contact pressure or fixture in place if
necessary. Optimum bond line thickness ranges from 0.005 to 0.020 inch; shear strength
will be maximized with thinner bond lines, while peel strength reaches a maximum with
thicker bond lines.
Excess uncured adhesive can be cleaned up with ketone type solvents.*
*Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow the
manufacturer’s precautions and directions for use.
Surface
Preparation
3M™ Scotch-Weld™ Structural Plastic Adhesives are designed to be used on metal, wood,
and most plastic surfaces. The following cleaning methods are suggested for common
surfaces:
Steel:
1. Wipe free of dust and dirt with pure solvent such as acetone or isopropyl alcohol.*
2. Sandblast or abrade using clean fine grit abrasives.
3. Wipe again with clean solvent to remove loose particles.*
Aluminum:
1. Wipe free of dust and dirt with pure solvent such as acetone or isopropyl alcohol.*
2. Sandblast or abrade using clean fine grit abrasives.
3. Wipe again with clean solvent to remove loose particles.*
4. When using a primer, apply adhesive within 4 hours of primer application.
Plastics/Rubbers:
1. Wipe with isopropyl alcohol.*
2. Abrade using fine grit abrasives.
3. Wipe with isopropyl alcohol.*
Glass:
1. Solvent wipe surface using acetone or MEK.*
2. Apply a thin coating of a silane adhesion promoter to the glass surfaces to be bonded
and allow to dry completely before bonding.
*Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow the
manufacturer’s precautions and directions for use.
