BestSeal EP737

BestSeal EP627 is suitable for protective coating of steel, wood, concrete structures, floors, walls, mortar, natural stone, artificial stone, etc.

• Low viscosity with high penetration capability.
  Excellent adhesion to cement-based substrates, metals, epoxy, polyurethane, polyester, and more.
  High gloss finish enhances the aesthetics of structures.
  High resistance to abrasion, chemicals, and aggressive environments, extending service life.
  Provides waterproofing and surface stain resistance.
  Easy application using common tools such as brushes, rollers, or spray equipment.
  Suitable pot life allows easy application and material savings.
  Can be diluted with solvent to adjust viscosity for specific application conditions.

SURFACE PREPARATION

• The substrate must meet the minimum strength requirements (compressive strength ≥ 20 MPa, tensile strength ≥ 1.5 MPa).

• The surface must be level, sound, and dry (maximum moisture content of 4%).

• All contaminants, debris, and dust must be properly cleaned.

APPLICATION PROCEDURE

Coating system:

• For porous or pitted surfaces, repair with BestBond or BestRepair before applying BestSeal EP737.

• For highly absorbent, weak, or porous substrates, apply a minimum of 3 coats of BestSeal EP737 or until full saturation is achieved without ponding.

• For smooth, dense surfaces with moderate roughness, apply a minimum of 2 coats of BestSeal EP737.

• For surfaces already coated with epoxy, polyurethane, polyester, etc., apply a minimum of 1 coat.

Mixing:

• Add component B into component A according to the specified ratio. Use an electric mixer or suitable mixing equipment (300–400 rpm) to mix for approximately 3 minutes or longer until a homogeneous mixture is achieved.

• Allow the material to stand for at least 10–15 minutes, then remix before application.

Application:

Can be applied using a brush, short-nap roller, or spray equipment.

Notes:

• Do not use material that has exceeded its pot life.

• The application area must be well-ventilated, and application should proceed in the direction of airflow.
  Do not smoke during the application process.

CLEANING

• Use BestThinner SC01 to clean tools immediately after use and before the coating begins to cure.

SAFETY INSTRUCTIONS

• Both components are classified as hazardous and flammable and may cause allergic reactions on sensitive skin. Protective gloves, masks, and safety goggles must be worn during application. Avoid direct skin contact.

• In case of contact with eyes, nose, mouth, etc., rinse immediately with plenty of clean water and seek medical attention at the nearest healthcare facility.

• Keep away from fire, sparks, and heat sources during application.
