PURASEAL 150

PURASEAL 150 is a high-performance, fully elastic, single-component, polyurethane-based material for concrete and expansion joints and various adhesive applications.

Product code: 205.30096

 

Application Areas

PURASEAL 150 is a concrete joint filler and various-purpose elastic adhesive material, therefore, it is used in many different areas.

  • In all types of construction work both indoors and outdoors
  • In filling concrete and expansion joints in horizontal and vertical directions
  • In protection of concrete and structures from temperature, vibration, and other impacts (up to 25%)
  • In adhesion of construction materials such as natural stone, ceramics, tiles, wood, aluminum, glass, metal, brick, and gypsum plasterboard • In assembly, decorative, and roofing works requiring flexible adhesion and waterproofing
  • In internal and external gluing of various ready-made concrete elements, stairs, window sills, thresholds, and skirting boards
  • In the installation of ventilation systems

 

Advantages

As a filler:

  • Easy to prepare and apply
  • Dries in the air and the presence of moisture
  • Does not bubble when used
  • High elasticity
  • Resistant to weather and seasonal conditions, does not change physical properties
  • High viscosity, does not flow when applied
  • Resistant to various chemicals and UV radiation
  • Waterproof under all conditions
  • Resistant to corrosion
  • Reduces impacts by accepting vibrations and blows
  • Fills cracks

 

As adhesive:

  • Ensures good adhesion to concrete, metal, glass, and other building materials
  • No need for the separate anchorage of the adhering part
