Pacer MR-3000 Moisture Resistant Cyanoacrylate Adhesive

Description

Pacer MR-3000 is a high-viscosity moisture-resistant cyanoacrylate adhesive for joints that need more gap coverage and better bead control than a thin instant glue. The Pacer MR Series data sheet places this grade at 2500 to 3500 cP, with published moisture resistance, thermal cycling strength, and a typical gap capability around .020 inch for parts that do not fit tightly.

Pacer MR-3000 Benefits

• High viscosity helps the adhesive stay in place on wider bond lines, vertical surfaces, and uneven parts.
• Moisture-resistant chemistry is intended to retain tensile shear strength in humid service conditions and after hot water exposure.
• Typical .020 inch gap capability gives more room for workpiece alignment than lower-viscosity cyanoacrylates.
• Fixture time of about 1 to 5 minutes supports setup on larger assemblies before the bond reaches handling strength.
• Compatibility with metals, ceramics, rubbers, and plastics makes it useful for repair, assembly, and maintenance work.

This grade is a practical choice when a standard instant adhesive runs too thin or starves the joint. Buyers often use it for heavier repair work, larger surface contact areas, and applications where a slower, thicker cyanoacrylate makes placement easier without moving to a two-part system.

Common Applications for Pacer MR-3000

• Bonding metal and plastic parts with slight gap variation or rougher fit-up.
• Handling repair work in marine, transportation, and general manufacturing settings.
• Securing rubber or ceramic components where a thicker adhesive bead is easier to control.
• Supporting maintenance jobs exposed to humidity, washdown, or thermal cycling.

Pacer MR-3000 Technical Details

• Base chemistry: ethyl hybrid cyanoacrylate.
• Published viscosity: 2500 to 3500 cP.
• Typical gap: .020 inch.
• Tensile strength on steel: 4,500 psi.
• Temperature use range: -65 F to +260 F.
• Specification compliance: MIL-A-46050C Type II Class 3 and A-A-3097 Type II Class 3.

Pacer advises using clean, oil-free parts and a minimal adhesive amount for best results, with about 80 percent of full strength developing in 15 to 30 minutes after fixture. Unopened material refrigerated at 40 F can achieve about one year of shelf life under the stated storage conditions. For broader adhesive industry reference, review The Adhesive and Sealant Council.
