Description
Chem-Set UltraLok SI-500 is a clear surface insensitive ethyl cyanoacrylate adhesive supplied in a 1 lb bottle. The adhesive is made for fast fixture work on similar and dissimilar surfaces, including dry or acidic substrates where a general instant adhesive may need more time to set.
UltraLok SI-500 Benefits
- Surface insensitive formula supports difficult bonding conditions on dry or acidic parts.
- Clear liquid appearance works well where a visible adhesive line should be limited.
- Medium viscosity range helps balance flow control with wet-out on small parts.
- One-part cyanoacrylate format supports fast bench assembly without mixing.
- 1 lb bottle is useful for production cells, repair departments, and refill workflows.
Cyanoacrylates cure quickly when thin adhesive films are pressed between close-fitting parts. This grade is useful when operators need a fast set on plastics, rubber, metal, or mixed substrates and want a bottle size that supports repeated shop use. Always confirm surface condition, joint gap, fixture time, and ventilation requirements against the technical data sheet and SDS before production release.
Common Applications for UltraLok SI-500
- Bonding small plastic, rubber, and metal components in assembly work.
- Repair jobs where quick fixture strength helps keep parts moving.
- Production benches that need a surface insensitive instant adhesive in a larger bottle.
- Maintenance and sign shop work involving close-fitting parts and fast handling.
Compatible Materials and Process Checks
- Similar and dissimilar surfaces listed for the SI series.
- Close-fitting joints where cyanoacrylate can form a thin bond line.
- Dry or acidic surfaces that slow some standard instant adhesives.
- Primer or accelerator use only when the application and adhesive data support it.
