Description
This is the 415ml cartridge of LORD Maxlok MX/T3S, part number 3031981, and the only size the grade is offered in. It is a two-component structural acrylic mixed 4:1 by volume with LORD Maxlok MX accelerator, used to replace welding, brazing, riveting and mechanical fastening on metal, composite and plastic assemblies. Work time is 3 to 5 minutes and handling strength comes at 6 to 8 minutes, the fastest cycle in the Maxlok family. Mixed, it is a grey non-sag paste. Made in the USA.
| Cartridge change: this 415ml cartridge (part 3031981) replaced the original 375ml cartridge (part 3019950). The two packages are not interchangeable. The 415ml requires a different gun and a different mixing tip. If you are reordering against an old part number, check your dispensing equipment before the material arrives. |

Running the 415ml Cartridge
- Takes a 4:1 gun built for 400 to 415ml cartridges. We stock the Albion B26T400X4 manual, the Albion AT400X4 pneumatic and the Albion E18T400X4 cordless.
- Needs an F-system mixing tip at 8 mm with 18 elements. Parker’s own LORD 3032007 or the Mixpac MFHX 08-18T.
- Level the plungers before the mixer goes on, expelling a small amount of material so both sides are even. Then fit the tip and purge a mixer’s length to waste.
- Watch the color coming out of the tip. Even grey means the mix is thorough; streaky means the mixer has not cleared yet. That is the only mix check you need on a cartridge.
- Mate the parts inside the 3 to 5 minute work time and clamp until handling strength. Do not re-expose the adhesive to air once mated, and correct alignment by sliding rather than lifting.
- Consider the pneumatic or cordless if you run these daily. A 415ml cartridge of heavy acrylic paste takes real hand effort, and with a 3 to 5 minute window, fatigue partway through a bead shows up as an uneven bond line.
- Clean tools with isopropyl alcohol, acetone or MEK before cure. Keep unopened cartridges below 80°F and out of direct sunlight.
Common Applications
- Replacing spot welds, rivets and mechanical fasteners on sheet metal assemblies
- Bonding aluminum, hot dipped galvanized and electrogalvanized steel
- Cross bonding dissimilar metals where galvanic separation matters
- Trailer, truck body and utility vehicle panel and trim bonding
- Sign fabrication and architectural metal assembly
- Production runs where a fast fixture turn is the constraint

Frequently Asked Questions
Will my old 375ml gun work with this cartridge?
No. The 415ml cartridge that replaced the 375ml package takes a different gun and a different mixing tip. If you are switching from part 3019950 to 3031981, plan on new dispensing equipment. Call us and we will match the gun and tip to what you are running.
What gun and mixing tip does the 415ml need?
A 4:1 gun built for 400 to 415ml cartridges and an F-system mixing tip at 8 mm with 18 elements. We stock Parker’s LORD 3032007 tip and the Mixpac MFHX 08-18T, with Albion 400 Series guns in manual, pneumatic and cordless.
Is the 415ml the only size for MX/T3S?
Yes, the 415ml cartridge is the only size currently offered in this grade. If you need a 50ml cartridge, LORD Maxlok MX/T6S is the only Maxlok grade available in that size, with a 6 to 9 minute work time instead of 3 to 5.
How long do I have once it is mixed?
3 to 5 minutes at 77°F, with handling strength at 6 to 8 minutes and complete cure in 24 hours at room temperature. Parts must be held in contact for the entire cure. Modest heat below 150°F (66°C) will speed it up.
Can I save a partially used cartridge?
Yes. Leave the used static mixer in place on the cartridge to seal it, then fit a fresh mixer and purge before the next bead. Store it below 80°F and out of direct sunlight. Unopened components keep nine months from date of manufacture.
