Technical Information
Product Description

A hybrid hot spray coating technology which offers a fast cure, excellent abrasion resistance and provides a seamless coating used for various applications. It is a volatile free system which is applied in a 1:1 mix ratio with a plural component spray equipment.

ARMATUREA H1 is composed of Polyol Component (A), a Hybrid Polyurea Polyol and Isocyanate-Component (B), a Low function prepolymer.

Advantages
  • Eco-friendly, low VOC
  • Flexible, excellent elongation
  • Excellent thermal stability
  • Good chemical 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 D412
  • ASTM D624
  • ASTM D4060
  • ASTM D2240

Application Information
Instructions for use

Surface Preparation

Concrete

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. Concrete must have a minimum pull off strength of 1.5 N/mm².

Metal
The metal surface needs to be prepared by means of sand blasting to near white. The surface profile will ensure adequate mechanical adhesion. Solvent cleaning is needed to remove the oil and grease.

Priming

Concrete
A primer is generally needed to achieve an adequate adhesion. Monneli Ureaprime EP1 can be applied at 100microns DFT.


Metal/Steel

If priming is needed, this should be done within 8 hours after the sandblasting to prevent any flash rusting.

Machine Conditions

  Mixing Ratio    1 : 1 (volume)
    Component temperatures (Depends of weather condition)   70-75°C
  Component pressure   120 - 180 bar

Mixing

Use 1:1 ratio pump, with appropriate material heaters, as required for individual application.

Environmental Conditions

  Substrate and ambient temperatures   5°C - 35°C
    Substrate moisture content   ≤ 4%
  Relative humidity   ≤ 85%

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.

Additional Information
Health & Safety

The isocyanate component irritates the respiration system, eyes and skin. This can have allergic reactions if inhaled or when comes in contact with skin. The required measurements indicated in safety data sheet should be noted during handling of isocyanate. The same procedure should also be applied during handling of a system (polyol) considering the risk available. Please refer to MSDS for additional information.
