Polyester resins

containing styrene/free of styrene

This is the classic reaction resin type that is used to produce the 2-component injection mortar, whereby both unsaturated polyester resins dissolved in styrene (classic resin type) and styrene-free unsaturated polyester resins are used, in which styrene-related monomers act as reactive solvents . The 2-component injection mortars produced from this are very light and can be processed quickly. In addition, the unsaturated polyester resins typically have a limited chemical resistance (including in alkaline medium).

  • Base: unsaturated polyester resin
  • Classic composite mortar system
  • Performance: standard
  • Ideal for standard applications - especially in masonry and perforated brick
  • Universal formulation
  • Suitable for use in natural stone (styrene)
