7. Technical Specifications

8. Chemical Resistance

Each NEWTECOAT product formulation has varying degrees of resistance to specific chemicals. PUA-Brush materials are resistant to a wide range of chemicals. The following information and technical data are representative or typical only and are not intended for specification purposes. Please contact your NEWTECOAT technical representative and distributor for specific advice on chemical resistance before applying these products.

• R – durable, resistant
• RC – Slight surface change, fading but no effect on hardness

9. Material Application

1. Surface preparation
– Concrete
• Concrete and mortar surfaces must be fully cured (over 28 days);
• Check the concrete surface, if there are holes or holes, they must be patched with specialized repair mortar;
• Cracked or seeping areas will be grooved and sealed with sealant;
• Ensure that no contamination affects adhesion, the allowable moisture content of the substrate is below 8%;
– Metal
• All dirt and impurities must be completely removed according to the supervisor’s instructions;
• The surface must be completely dry before coating.

2. Apply NEWTEC Primer
• Apply primer at a rate of 0.2~0.3 kg/m2. Can use spray, brush, or roller.
• Recommended repainting interval is 4 hours at 25oC
3. Apply NEWTECOAT PUA-Brush
– After about 2 hours at 25oC after applying primer (base paint), prepare a NEWTECOAT PUA-Brush paint mixture with a mass ratio of 1:2 according to the exact calculation of the amount applied to each painted area with a minimum thickness of 1.5mm;
* Mixing process
• Stir component B (color component) for about 2~3 minutes. Then pour all component A (light yellow) into the tank of component B and continue mixing for at least 3 minutes until the mixture is homogeneous.
– Note: Mix with a spiral paint mixer at low speed and during the mixing process, the stirring blade should be immersed deep in the mixture to avoid air entrainment.
• Apply NEWTECOAT PUA-Brush immediately after mixing with a specialized trowel on the surface where the primer has been applied.
• Use a spiked roller to break the surface foam.
• Apply a single layer with the approved rate.
• In case of open-air construction, apply a NEWTECOAT Topcoat protective coating. The coating after construction has high aesthetics, very good abrasion resistance, and is durable under all weather conditions.
Please refer to the product’s technical documentation
• In case of finishing the surface with mortar or tile adhesive layers, after applying the NEWTECOAT PUA-Brush layer for about 30
minutes, sprinkle or spray the surface of the NEWTECOAT PUA-Brush layer with completely dry sand, grain size 0.3 – 0.8mm. This helps
to create a rough surface for good adhesion to the top finishes.
* Note
• Only apply in dry, favorable weather conditions, do not apply when it is about to rain.
* Cleaning tools
• Clean construction tools with solvents such as xylene, and toluene…

10. Safety

• Solvent-based products are flammable and should be kept away from heat and ignition sources;
• Use only in well-ventilated or well-ventilated areas;
• Wear safety glasses, shoes, and gloves during application;
