Applications

  • Specifically for high-strength sealing and bonding of virtually all materials.
  • Elastic bonding and sealing in automotive, bus, caravan, truck and train structures.
  • Universal joint sealing and material bonding in industry, marine and automotive.
  • Stain-free sealing and bonding of porous materials and sensitive substrates.
  • Bonding and sealing of corner profiles, roof and floor systems in the transportation industry.
  • Multi-purpose assembly and construction adhesive, suitable for virtually all construction materials.
  • Bonding of polyester structural components to metal and aluminum frames.
  • Structural bonding in vibrating structures of buildings, vehicles and equipment.
  • Sealing and bonding in bodywork, trailer, ship, container and air duct construction.
  • Repair adhesive sealant for damaged MS-Polymer® joints and adhesive joints.

Properties

  • Low odor, blow and shrinkage-free curing.
  • Permanently permanently elastic.
  • Excellent adhesion without primer on almost all, even damp substrates.
  • Extremely high tensile strength, mechanical resistance, final strength and rapid strength build-up.
  • Does not stain or bleed in porous materials, does not cause edge zone contamination.
  • Easy to use and versatile in application.
  • Suitable for bonding or sealing almost everything indoors and outdoors.
  • Paintable with dispersion-based paint and lacquer systems.
  • Plasticizer-, phthalate-, isocyanate-, solvent- and silicone-free.
  • Perfectly sandable and grindable after complete curing.
  • Compatible with foodstuffs, PVB films, laminated glass and silver-coated mirrors.
  • Excellent absorption of acoustic and mechanical vibrations and oscillations.
  • Durable UV, weather, water, moisture, aging resistance.

Application conditions

  • Application temperature (ambient and substrate) between min. +5°C and max. +35°C.
  • On load-bearing, tolerant, clean, grease- and dust-free substrates.
  • Remove loose substrate particles completely with a suitable brush.
  • Completely degrease greasy substrates with SEAL-IT® 510 CLEANER.
  • Apply in correct joint dimensions to accommodate movements.
  • SEAL-IT® 353 SUPER-STRONG has a broad adhesion spectrum, however prime highly porous substrates with SEAL-IT® 520 PRIMER. Non-porous substrates with minimal adhesion should be pretreated with SEAL-IT® 525 CLEAN & BOND.
  • SEAL-IT® 520 PRIMER can be applied easily, quickly, cleanly, evenly and not excessively using SEAL-IT® 590 PRIMERFLES + KWAST, under proper temperature and substrate conditions (see TDS).
  • As soon as the primer is dry, apply SEAL-IT® 353 SUPER-STRONG as soon as possible.
  • Wet-finish for skin formation using SEAL-IT® 550 FINISH and smoothen immediately afterwards using SEAL-IT® 590 FINISHING PADDLE, FINISHING PADDLE QUARTET or FINISHING WOOD.
