PERMABOND® 943 Cyanoacrylate
PERMABOND® 943 is a low-odor, non-fogging alkoxyethyl cyanoacrylate designed for clean, aesthetic bonding. It eliminates the frosting or fogging that can occur with other adhesives, especially in humid environments. The stable formulation bonds most materials and ensures improved worker comfort and visual quality of finished parts.
PERMABOND® 943 Features:
- Low odor for improved user experience
- Non-frosting for better surface appearance
- No mixing or heat cure required
- Bonds a wide range of materials
- 100% reactive with no solvents
PERMABOND® 943 Applications:
- Aesthetic assemblies requiring clean bondlines
- Clear plastic bonding
- Electronics and consumer products
- General-purpose manufacturing with odor sensitivity
