Chem-Set CA5 is a medium-high viscosity cyanoacrylate super glue for fast bonding and gap filling. Its 1,200–2,400 cP formula bonds metals, ceramics, plastics and elastomers, with typical handling strength in just 5–10 seconds on steel, Buna N rubber and phenolic. It is a practical choice for small-part assembly, workshop repairs and applications requiring more gap-filling capability than conventional instant adhesives.
Key Benefits
- Fast handling: Typical fixture time of 5–10 seconds on tested materials helps keep assembly moving.
- Gap-filling performance: Accommodates bond gaps up to 0.017 in (0.43 mm).
- Versatile bonding: Suitable for metals, ceramics, plastics and elastomers, including passivated metal surfaces. The TDS also identifies polyacetals as a suitable application; test the actual substrate before use.
- Strong cured bonds: Typical steel lap-shear strength of 2,900–3,200 psi after full cure.
- Clear appearance: Colorless adhesive for discreet bond lines.

Performance values are typical, not guaranteed specifications. Cure speed and bond strength depend on surface preparation, materials, gap, temperature and humidity.
Choose Your Shelf Life
- Fresh Batch: Fresh-batch inventory; refer to the bottle's lot and expiration information for its actual remaining shelf life.
- Short Shelf Life (1-3 Mths Left): Product with approximately one to three months remaining before its labeled expiration date.
- Recently Expired: Product past its labeled expiration date. Published performance values should not be assumed for expired material; test suitability and cure performance before use.
Directions for Use
- Clean and dry both surfaces, removing grease and contamination with a substrate-compatible cleaner.
- Apply adhesive sparingly to one surface.
- Bring parts together promptly, align correctly and press to spread the adhesive into a thin film.
- Hold without moving until handling strength develops. Allow 24 hours for full strength under suitable conditions.
Storage and Handling
Store tightly closed in the original container at 35–45°F (2–7°C). Let the closed bottle reach room temperature before opening to help prevent condensation that can shorten shelf life. Use with adequate ventilation and appropriate eye and hand protection. Bonds skin and eyes rapidly; avoid contact. Do not use cotton or other absorbent gloves. Read the SDS before use.
