Product Description
PERMABOND® 2050 Flexible Cyanoacrylate Adhesive is a medium-high-viscosity, single-component ethyl cyanoacrylate adhesive designed for flexible, semi-porous, and dissimilar-material bonding. Its toughened formulation provides improved peel performance together with resistance to impact, vibration, thermal shock, and thermal cycling. The adhesive has a viscosity of 1,200–1,800 mPa·s at 25 °C and fills gaps up to 0.2 mm. Typical handling strength is reached in 5–15 seconds depending on the substrate, with full strength developing in 24 hours. It is suitable for plastics, elastomers, and metal assemblies where a more flexible instant adhesive bond is required.
Key features
- Flexible, toughened formulation: Provides improved peel strength and resistance to impact, vibration, thermal shock, and thermal cycling.
- Fast fixture performance: Typical handling strength is reached in 5–15 seconds depending on the bonded substrate.
- Controlled medium-high viscosity: A viscosity of 1,200–1,800 mPa·s supports accurate dispensing and gap filling up to 0.2 mm.
Applications / Suitable for
- Bonding flexible or semi-porous surfaces
- Bonding dissimilar materials
- Assemblies exposed to vibration or impact
- Applications exposed to thermal shock or thermal cycling
- Bonding plastics, elastomers, and metals
