Product overview

Engineered for its duty

5115X70 is the backbone of many heavy-duty protective coating systems: marine paints, steel-structure primers, container and vehicle coatings, and high-build industrial floors. Its polyamide chemistry wets substrates and fillers exceptionally well, tolerates imperfect surface preparation better than most amine systems, and forgives mixing errors thanks to its broad stoichiometric window.

Beyond coatings, 5115X70 is a proven room-temperature adhesive and repair resin for stone, metal, glass, concrete, ceramic tile and wood — valued where bond strength, flexibility and long operating time must coexist.

Key benefits

Why formulators specify it

  • Wide mix-ratio window
    Tolerant stoichiometry reduces mixing errors on site.
  • Long operating time
    Comfortable application windows even in warm conditions.
  • Low viscosity, easy application
    Flows and wets substrates for smooth, void-free films.
  • Excellent toughness & abrasion resistance
    Films withstand impact, abrasion and substrate movement.
  • Excellent water & chemical resistance
    Reliable protection in marine and industrial environments.

Applications

Where it is used

  • Marine, steel-structure, container, vehicle and heavy-duty floor protective coatings
  • Anti-corrosion primers, mid coats and top coats
  • Room-temperature bonding and repair of stone, metal, glass, concrete, tile and wood
  • Adhesives, electronic industry and composite materials

Handling & safety

Application and storage

Application

Suitable for conventional and airless spray, roller or brush. Ventilate work areas when using solvent-borne systems and observe local VOC regulations.

Data are proven correct under specific conditions; pre-test on your own formulation before volume use. Henster accepts no legal liability for unsupervised application data.

Storage

Store sealed in the original container in a cool, dry, well-ventilated area away from ignition sources. Shelf life: 12 months. Keep containers closed and away from light; gradual darkening during long storage is normal.

Packaging

20 kg and 200 kg net steel drums.

Safety

Contains organic solvent — keep away from heat, sparks and open flames. Use appropriate respiratory protection in confined spaces.
