HSC-A90P/R

- Two parts, ultra fast curing, hybrid polyurea, sprayapplied elastomeric coating system. It provides premium quality, long-life protective coating to concrete and metal substances on major civil and construction projects.

▶ TECHNICAL DATA

▶ Features 

* Untra fast curing spray coating system. 

* Simple application by spray machine.

* Good adhesion to the substrates. 

* Good physical performances 

* Good resistance against abrasion, chemical.

▶ Uses 

* Most areas of protective coating, lining, flooring and waterproofing. 

- Concrete, steel, tank, bridge, etc. - Ultra fast cure allows vertical application.

▶ Color 

* Green, Grey 

- Custom colors are available. 

* Tend to yellowish and become chalking after exposure to UV light. It should be combined with Varo-Top HG for UV-resistance and durability.

* HSC-A9OR [Polyol] : 200kg / Steel Drum 

* Mix Ratio (PR) = 1:1 by volume

▶ Storage 

* Use within six (6) after manufacturing date written on the label. 

* Store in cool, dry and well-ventilated place. 

* Avoid exposure to humidity and UV. 

* Avoid contamination by water, alcohol, etc. 

* Keep away product from heat, spark and flames.

▶ Surface Preparation 

* Surfaces must be sound, smooth and free from dust, laitance, oil or other contaminants.

▶ Application - Professional use only. 

* Priming 

- To inhibit pin-holes and increase the adhesion to the surfaces, porous surfaces should be coated by primer (Varo-BP is recommended) at 0.25Kg/m in 0.1mm dry film thickness. 

* Coating

- HSC-A90R[Polyol] compound should be agitated before and during use. 

- Required machine spray setting as follows.

* Material temperature 20-250 * Main heater temperature 60-650 

* Line heater temperature 60-650 

* Spray Pressure 2.500-2.800psi

- Keep the distance between the surfaces and the spray gun about 50~60cm, and apply it at right angles to the top and bottom, left and right at regular intervals. 

- Do not apply product unless concrete has cured at least 28days at 200 and over 80%RH or equivalent. The surfaces temperature and moisture content should be lower than 400 

- Do not apply product when the temperature is below 50 

- Cover the fully dried membrabne by Varo-Top HG R/H for color-fast and endurance.

- Please refer to the general guideline for complete information. 

* Recommended Spray machine 

- Over grade of GRACO E-XP2 or E-10
