Theoretical coverage

(at DFT 100- 200m)

0.102~0.204 L/m2  ;

9.8 ~ 4.9 m2/L

Service temperature -60 to 150 0C (dry)

Application Data

Mixing ratio : Part A : Part B = 85 : 15 ( by weight)

Application Method : airless spray, roller, brush

Mixing Procedure : Add part B into part A and power mix for at least two minutes or until homogeneous.
Drying schedule : Drying by water evaporation and chemical cross linking. Higher film thickness, insufficient ventilation, or lower temperature will require longer drying time. Excessive humidity or condensation on the surface can interfere with the drying cause discoloration and may result in a surface haze. Any haze or contamination  must  be removed by water washing before recoating.

This product requires the substrate temperature to be above the dew point ( + 3~5 0 C). The Epoxy finish tends to chalk or yellowing under uv exposure.

Condition of Application

Use brush or roller with 1/8” nap . Apply at sufficient thickness and avoid repeating rolling to have good levelling.

Temperature : Min 5 0 C ; Max 50 0 C
Humidity : Maximum 85 % R.H.
For Airless spray      :-
Tip Size : Graco 625, 725 or equivalent
Paint Output pressure : 14.7 – 17.7 MPa (g)
Viscosity : 2.5 ~ 3.0 Pa.s
Thinning : 0 – 5 % by volume

Surface Preparation

General :
Surfaces must be clean and dry, all contaminants like dirt, dust , oil must be remove by appropriate method to ensure good adhesion.

 

Abrasive blast clean
Abrasive blast clean to Sa 2.5 (ISO-8501) or SSPC- SP6. In case of hydro blasting or hydro jetting to remove existing coating, ginger rust should be remove and blow dry before application. Surface profile must be a minimum of 50 microns.

 

Concrete Structure
Concrete must be cured for at least 30 days prior to coating and must be free from moisture as much as possible. The surface must be cleaned, free from any contaminant, laitance and loose film. Broom cleaning, vacuum cleaning, air blast cleaning, steam and water cleaning are suitable as outlined in ASTM D4258.

 

Shop primed steelwork
Weld seam and damaged area should be cleaned to a minimum St3 or SSPC-SP3. The shop primed steelwork should be repair for any rust and free from any contaminant with suitable secondary surface preparation such as spot blast , sweeping or power tooling. Apply the primer and middle coat.

 

Safety Precaution & Clean-Up

 

Safety :

Read and follow the material safety data sheet (MSDS) before use. Employ normal safety precautions. Put on necessary personal protection equipment when handling and using this product.
 Ventilation : when working in a confined workplace, thorough air ventilation must be used during and after application until the coating is cured. The ventilation system should be effective to prevent solvent vapor concentration from reaching a lower explosion limit for the product and to ensure exposure limit to the personnel is below the permissible exposure limit.
Caution : All electrical equipment and installations should be made and properly grounded. In areas where explosion hazards exist, workmen should be used non-ferrous tools and conductive and non-sparkling shoes.
Clean-up : Use Hana Paint polyurethane thinner (Hana Thinner U)  or hydrocarbon solvent for cleaning. Observe safety precautions when using the solvents. In case of spillage, absorb and dispose of the material and used container according to local required regulations or through a licensed waste collector.
