Chem-Set CA2400 Thick Cyanoacrylate Super Glue – High-Viscosity Gap-Filling Instant Adhesive

Description

Chem-Set™ CA2400 is a high-viscosity, thick-set cyanoacrylate adhesive designed for gap-filling applications where low- or medium-viscosity super glues are not effective. With a viscosity range of approximately 1,200–2,400 cP, CA2400 provides excellent control, reduced run-off, and improved build on uneven or imperfectly fitted parts.

Engineered for industrial assembly, maintenance, and repair operations, CA2400 delivers fast fixture times, rapid strength development, and durable bonds across a wide range of substrates including metals, ceramics, plastics, and elastomers. Its thick consistency makes it ideal for vertical surfaces, overhead bonding, and applications where precise placement and gap bridging are required.

CA2400 is also widely used in stone fabrication as a thick-grade cyanoacrylate for chip repair, edge repair, and surface restoration. Its gap-filling capability and clear cured appearance make it well suited for cosmetic repairs where appearance, speed, and control matter.

Technical Properties

Physical Properties of Uncured Adhesive

Typical Cure Performance at 25°C

Fixture times vary based on surface condition, temperature, humidity, and gap size. Cure speed can be increased using Chem-Set activators when required.
