Main features
- 2 to 3-Second Handling Time
- Surface-Insensitive Acidic-Substrate Bonding
- Low-Viscosity Wicking Post-Assembly Bonding
Product Description
Permabond® 790 Cyanoacrylate is an extremely fast-setting, low-viscosity, surface-insensitive adhesive designed to rapidly bond a wide variety of substrates. Its specialized formulation readily bonds acidic surfaces such as wood and plated metals, along with plastics, ceramics, and elastomers. Featuring a highly penetrative wicking viscosity, this 100% reactive, solvent-free adhesive is ideal for post-assembly applications and minimizes the occurrence of frosting and fogging during cure.
Key features
- Extremely fast setting: Single-component formula polymerizes rapidly upon contact with surface moisture, delivering fixture handling times of 2-3 seconds on steel and rubber.
- Surface insensitive: Expertly engineered to rapidly bond notoriously difficult acidic surfaces, including wood and plated materials.
- Low wicking viscosity: The exceptionally low 2 cP viscosity enables superior wicking action, making it perfectly suited for post-assembly penetration and application.
Applications / Suitable for
- Bonding acidic surfaces such as wood and plated materials
- Adhering plastics, metals, ceramics, and elastomers
- Post-assembly applications utilizing wicking penetration
