Powerflex is a unique adhesive technology combining advantages of both structural- and elastic adhesives. Powerflex makes the new generation SikaForce® adhesives an effective solution for bonding and assembly of lightweight vehicles, fiberglass boats, metal fabrications and virtually any application that requires a strong, reliable bond.
SikaForce®-800 SERIES
Key features of SikaForce® adhesives with Powerflex inside
SikaForce®-800 SERIES provides unique mechanical characteristics making it an ideal solution for mixed material- and composite bonding. This new generation of structural adhesives brings innovations to market trends and is becoming an integral part when bonding modern lightweight materials.
- Combines the high strength of structural- with the flexibility of elastic adhesives
- Keeps flexibility even at low temperatures
- Provides stable mechanical strength over service temperature
- High energy absorption capacity
- No smell compared to other technologies
Constant performance over service temperature
While 1-component polyurethane adhesives provide excellent cold temperature performance regarding elongation, their potential in strength (E-Modulus) is insufficient for high strength bonds. In contrary to this, 2-component structural adhesives offer enormous potential for mechanical strength but are lacking the necessary flexibility at low temperatures needed for bonding mixed materials. Standard 2-component adhesives also show a significant loss of mechanical strength at elevated temperatures (e.g., 80°C). The new generation of SikaForce® 2C polyurethane adhesives with Powerflex inside shows a substantially higher strength retention rate in the heat while keeping its elasticity over the entire service temperature.
Powerflex stands for a paradigm shift
The new SikaForce® structural adhesives feature a unique combination of structural strength and permanent elasticity. This key performance feature is a potential game changer in the composite industry as it allows to formulate SikaForce® structural adhesives with exceptional mechanical strength without compromising the elongation. Powerflex breaks the boundary of strength- and elongation ratio and is therefore becoming the preferred solution when bonding materials with different thermal expansion coefficients (e.g. CFRP and aluminum). The Powerflex technology therefore provides the end user with unimagined design possibilities involving composite materials.
