Scotch-Weld™ Multi-Material & Composite Urethane Adhesives DP6310NS and DP6330NS
are multi-purpose urethane adhesives for bonding a variety of composites, plastics, metals and
wood. They are high-strength bonders with some flexibility to accommodate thermal expansion and
contraction differences with dissimilar material bonding
3M
TM
Scotch-Weld™ Multi-Material & Composite Urethane Adhesives DP6310NS and DP6330NS
can replace rivets and screws in attaching composites to other substrates, providing a more
aesthetically-pleasing, fatigue-resistant bond line. They also bond well to most metals without
requiring priming.
Note: The following data are taken from tests conducted on a limited number of production runs. 3M
will continue to test samples from additional manufacturing lots and issue a new technical data sheet if
the results change.
Note: Unless otherwise indicated, all properties measured at 72°F (22°C).

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.

3M
TM
Scotch-Weld™ Multi-Material & Composite Urethane Adhesives DP6310NS and
DP6330NS are designed to be used on composites, 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.*
4. For best results, apply a primer to bare steel before bonding, such as an epoxy-based primer
or 3M™ Adhesion Promoter 111.
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.*
Plastics/Rubbers/Paints/Coatings:
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.
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.
3. 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.
4. Allow adhesive to cure at 60°F (16°C) or above until completely firm. Applying heat up to 200°F
(93°C) will increase cure speed.
5. 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.
6. 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.
