Pacer E-5 Ultra-Low Viscosity Cyanoacrylate Adhesive – 1 lb (453 g) Bottle

This 1 lb (453 g) bottle of Pacer E-5 is the production volume size of Pacer’s water-thin ethyl cyanoacrylate, 2 to 10 cP with .002 in gap capability. At 453 g it holds about 23 times what the 20 gram bottle does, which makes it the size for a line that wicks joints every day, a cell feeding automatic dispensing equipment, or a shop that fills its own applicator bottles off a bulk container. Same adhesive and same specification compliance as the smaller bottles, in enough quantity to stop reordering every other week.

Package Details

Full physical properties, cured state data, tensile shear numbers by substrate, and the viscosity selector for the whole series are on the main Pacer E-5 product page, or in the Pacer E Series technical data sheet (PDF).

Choosing the 1 lb

Same adhesive in all three sizes, so the decision comes down to how fast the bottle empties.

• 453 g against 20 g, or 16 oz against 0.70 oz, about 23 times the material. If a 20 gram lasts your shop a week or less, this is the size and the reorder cycle alone justifies it.
• This is a bulk container, not a bench bottle. Most shops draw from it to fill smaller applicator bottles or to charge a dispensing system, rather than handing the 1 lb to an operator.
• Refrigeration matters more at this size. A cold 1 lb bottle takes real time to reach room temperature, and opening it before it does pulls condensation into a lot of material at once. Plan the warm-up.
• Pacer’s one year shelf life is stated for unopened material stored per the data sheet. Buying more than a year of consumption does not save money.
• If you’re still qualifying E-5 on your substrates, start with the 20 gram and step up once the joint design and fit-up are settled. A wicking grade lives or dies on fit-up, so prove that before you buy a pound.
• Worth knowing if you’re standardizing across viscosities: E-5, E-40, and E-100 all come in a 1 lb. E-1500, the thick grade, is 20 gram only.

Performance in Production

• Enough volume to feed a daily wicking operation without a purchase order every other week, which is usually where the real cost of the small size shows up.
• Applied after assembly, so the station can align and clamp parts in one step and bond them in the next. On press-fit and slip-fit lines that simplifies the sequence.
• One free-falling drop covers about one square inch of bond area, so 453 g carries a substantial part count on small joints.
• Pacer states E Series cyanoacrylates are suitable for dispensing from the bottle or through automatic equipment, so bulk material fits both a manual line and an automated cell.
• 2700 psi tensile shear on steel is the highest in the E Series, which is worth designing around if your parts fit closely enough to use a wicking grade.
• At 2 to 10 cP this runs and migrates freely. Build the station around a flat or fixtured joint, plan for masking, and expect to keep it clear of threads and bearings.
• Decant only what gets used in a shift and keep transfer containers dry and capped. Cure rate tracks relative humidity, so open material in a humid shop behaves differently than the data sheet suggests.

Common Applications

• Daily production wicking of close-fitting assembled joints
• Press-fit and slip-fit part retention at volume
• Feeding automatic dispensing equipment on a bonding cell
• Filling shop applicator bottles from bulk
• Small metal and ceramic part bonding on steel and aluminum
• Contract manufacturing calling out MIL-A-46050C Type II, Class 1 or A-A-3097 Type II, Class 1

Frequently Asked Questions

How much adhesive is in a 1 lb bottle of Pacer E-5?

Net weight is 1 lb (453 g), about 23 times the 20 gram (0.70 oz) bottle. Pacer’s guidance is one free-falling drop per square inch of bond area, but Pacer does not publish a coverage figure per gram or a drop count. If you need to budget material against a part count, send us the part and we’ll help you work it out from a sample.

Is the 1 lb Pacer E-5 the same adhesive as the smaller bottles?

Yes, identical. Same ethyl cyanoacrylate, same 2 to 10 cP viscosity, same .002 in gap capability, same MIL-A-46050C Type II, Class 1 and A-A-3097 Type II, Class 1 compliance. Only the container changes. Nothing needs requalifying when you step up.

Which Pacer E Series grades come in a 1 lb bottle?

E-5, E-40, and E-100 are all available in a 1 lb bottle. E-1500, the thick 1300 to 1700 cP grade, is currently 20 gram only. If you’re standardizing a process on the thick grade and need bulk quantity, call us first.

Can I decant Pacer E-5 into smaller applicator bottles?

Pacer’s data sheet does not cover decanting, so treat this as shop practice rather than a manufacturer instruction. Shops do it routinely with bulk CA, and it matters more with a wicking grade because handling a pound of water-thin adhesive at a bench invites spills. Keep transfer containers clean, dry, and capped, and move only what gets consumed in a shift, since cure rate depends on relative humidity. If you need Pacer’s formal position on repackaging for a quality system, we’ll ask them.

Should a 1 lb bottle of Pacer E-5 be refrigerated?

Pacer recommends refrigerating unopened cyanoacrylate at 40F (4C) for optimum results, then bringing it to room temperature before opening. This matters more on a 1 lb than on a small bottle, because the larger mass takes longer to warm and opening it cold pulls condensation into a lot of material at once. Once opened, store in a cool, dry location. Stored per the data sheet, expect a one year shelf life.

Will Pacer E-5 hold on a vertical joint?

No. At 2 to 10 cP E-5 is essentially the viscosity of water and it will run off a vertical or overhead face and wick into areas you did not target. Design the station around a flat or fixtured joint. If part orientation cannot change, use E-1500 at 1300 to 1700 cP, or RX-50M Gel for a true gel.

What is the part number for the 1 lb Pacer E-5?

Our SKU is PAC-FG01013. The Pacer part number is FG01013 and the UPC is 0 87093 00201 2. On older Pacer paperwork the same item shows as Pacer item number 11740007.
