Pacer HI-500 High Impact Toughened Cyanoacrylate Adhesive

Description

Pacer HI-500 High Impact Toughened Cyanoacrylate Adhesive is a medium-high viscosity instant adhesive for metal, rubber, plastic, ceramic, and wood bonding where shock resistance and a controlled bead matter. The 400 to 600 cP viscosity gives assemblers more placement control than thin instant adhesives, while the 0.008 inch typical gap fill helps on close-fitting parts with slight mismatch.

Pacer HI-500 Benefits

• High impact cyanoacrylate formula helps bonded joints handle shock, peel, and vibration better than standard brittle grades.
• Medium-high viscosity supports controlled placement on small parts, trim, brackets, fixtures, and repair assemblies.
• Slow cure designation gives operators a short alignment window before the adhesive reaches handling strength.
• One-part chemistry removes mixing steps for production cells, service kits, and maintenance benches.
• Useful for dissimilar material bonding when clean, dry, close-fitting surfaces are available.

Use this grade when a thin cyanoacrylate runs out of the joint too quickly or when a general-purpose grade lacks the toughness needed for handling, vibration, or occasional impact. Test production substrates first, especially coated metals, flexible plastics, and elastomers, because surface condition and bond gap can change cure speed and final strength.

Common Applications for Pacer HI-500

• Metal to metal assembly where fast fixture and impact resistance are both needed.
• Rubber, plastic, and ceramic repairs in maintenance departments and fabrication shops.
• Small sign, display, trim, and fixture bonding where clamps are difficult to place.
• Prototype builds that need a stronger instant adhesive before moving to larger production lots.
• Bench repairs using a higher viscosity CA to keep adhesive in the bond line.

Compatible Substrates and Materials

• Steel, aluminum, and other clean metals.
• Rubber and many rigid plastics after compatibility testing.
• Ceramic, wood, and small mixed-material assemblies.
• Close-fitting joints that can benefit from 0.008 inch typical gap fill.

Packaging and Ordering

Choose this bottle for line-side adhesive stations, repair carts, and small assemblies that need a toughened instant adhesive with more body than low-viscosity CA grades.
