BestPrimer EP701
Solvent-based epoxy primer, two components
Advantages:
High penetration, enabling deep bonding into the material.
Bonds well with all material surfaces, including metal.
Improves aesthetics and significantly saves material for the subsequent finish coat.
High resistance to alkalis and aggressive corrosion.
Easy to apply with common tools such as brushes, rollers and spray guns, etc.
Long workable time, easy to apply and avoids material waste.
Low material consumption, making it very economical and efficient.
Can be diluted with solvent to adjust the viscosity to suit each specific application.

Applications
BestPrimer EP701 has low viscosity and high penetration, so it is used to create an interface primer between surfaces to be protected and epoxy-based BestCoat protective paints, increasing adhesion strength.
BestPrimer EP701 can be applied to concrete floors and bases, cement render, fiber-cement cladding panels, epoxy mortar, etc., for factories, warehouses, parking garages, etc.

Application instruction
Surface preparation:
The surface must reach the minimum strength (compressive strength ≥ 20 MPa, tensile strength ≥ 1.5 MPa). The base surface must be flat, dense and dry (maximum floor moisture 4%); impurities, debris and dust must be cleaned as required.
Coating system:
For highly absorbent and friable surfaces, apply at least 2 primer coats before applying BestCoat-line paints.
For flat, dense surfaces with medium roughness, only one coat of BestPrimer EP701 is needed after the surface has been cleaned by suitable means.
For surfaces previously treated with a hardener, dilute BestPrimer EP701 with 10-15% BestThinner SC01 before application.
To achieve high aesthetics and the required mechanical properties, the surface should be coated with at least 01 coat of BestPrimer EP701 and 02 finish coats, or one self-leveling coat of the BestCoat range.
Mixing:
Add component B into component A at the specified ratio. Use an electric mixer or a dedicated mixing machine (300 to 400 rpm) to mix for about 3 minutes or longer until homogeneous. Let the material stand for at least 10 ÷ 15 minutes and re-mix before application.
Application:
Can be applied with a brush, short-nap roller or pressure spray gun.
Notes:
Do not use material that has exceeded its working time.
The work area must be well-ventilated and application should proceed from the upwind direction.
Do not smoke throughout the application of the product.
Cleaning:
Use BestThinner SC01 to clean tools immediately after use and before the paint starts to cure.
Safety guidance:
Both components are hazardous and flammable and may cause irritation to sensitive skin. Wear gloves, a mask and safety goggles during application. Avoid direct skin contact with the product.
If splashed into the eyes, nose or mouth, rinse immediately with plenty of clean water several times before going to the nearest medical facility for timely and proper treatment.
Keep away from fire, electric sparks and heat sources during application.
