Product description
Three Bond 1796B – Activator for Cyanoacrylate Overview
The Three Bond 1796B Activator is an alcohol-based solution that can activate cyanoacrylate adhesives, thereby accelerating curing. The bond becomes ready for use more quickly and reduces bloom formation at the adhesive surface. It is compatible with all ThreeBond CA adhesives and ideal for applications with low humidity or large gaps.
Colorless, low viscosity of 0.90 mPa·s and density of 0.82 g/cm³ support a thin, uniform application that does not visibly affect surfaces. Shelf life is 6 Monate.
Curing times: 80 °C 20 min; 100 °C 15 min; 120 °C 10 min.
Application Field: Suitable at low humidity
This product is particularly suitable when humidity is low or there are gaps in which rapid activation of the CA adhesive is required. Compatibility with all ThreeBond CA adhesives ensures reliable results in production.
