Reactive Resins and Systems

POLYVERTEC® COMPOSITE SYSTEMS
STRUKTOL® POLYVERTEC® COMPOSITE SYSTEMS for composite applications and potting compounds

Fiber reinforced components (composites) based on reactive resin systems are used in many application areas:

  • Transportation (rail, shipping): railcar construction, ship superstructures
  • Wind energy: rotor blades
  • Sports and leisure industry: golf clubs, bicycles, fishing rods, etc.
  • Gliders: fuselage, wings and tail unit
  • Construction industry: stiffening elements, lamellas and re-bars ("construction steel mats")
  • Potting compounds

The properties of POLYVERTEC® COMPOSITE SYSTEMS can be adapted within wide limits to meet the different requirements of processing procedures as well as the properties of the finished fiber composite component. For the production of high-quality infusion and RTM molds (tooling), POLYVERTEC® Q-TOOL HT can be easily processed as a quartz-based polymer concrete in a casting process.

POLYVERTEC® COMPOSITE SYSTEMS can be combined in many ways with other STRUKTOL® products, such as POLYPHLOX® Flame Retardant modifiers or the STRUKTOL® POLYDIS® and POLYCAVIT® Tougheners product range.
