Technical Information
Product Description

ARMATUREA A1 is a two component pure aromaticpolyurea elastomer formulated for applications in concrete lining, corrosion protection and waterproofing. ARMATUREA A1 is designed to minimize problems associated with field applications and can be applied in the most problematic of ambient conditions since it is relatively temperature and moisture insensitive.

Advantages

  • Flexible, excellent elongation
  • Excellent thermal stability
  • Good chemical resistance
  • Excellent UV resistance
  • Seamless, resilient, non-cracking elastomer
  • Excellent corrosion protection
  • Low perm rate
  • Fast reactivity and cure time (No catalysts)
  • Return projects to service in 60 minutes
Compiliance Standard
  • ASTM D638
  • ASTM D4060
  • ASTM D2240
  • ASTM D4541
Packaging, Coverage / Consumption

Application Information
Instructions for use

Surface preparation

All surfaces must be dry, smooth, clean, sound, The surface of the substrate shall be sound, clean and uncontaminated.  

This preparation shall be such as to leave a sound expose surface free from dust, loose particles and any deleterious matter. If the surface is defective or has laitance, it must be cut back to a sound base.

New concrete or cementitious surfaces should be at least 28 days old and have moisture content not exceeding 5%. Old or existing surface should be refurbished mechanically to ensure clear and sound substrate.

Priming

Surface must be primed using UREAPRIME EP1. Once the primer has reached a tack-free status, the polyurea coating can be applied immediately.  Note that the entire primed surface must be coated within the day of application.

Mixing

Use 1:1 ratio pump, with appropriate material heaters, as required for individual application. Please contact Colmef for further information.

Application

ARMATUREA A1 must be spray applied using approved equipment. For application guidelines, please contact Colmef.

Cleaning

Clean equipment immediately after use. Cured product may be disposed of without restriction.  The un-cured isocyanate and resin portions should be disposed of according to local government regulations.
