BestPrimer EP701

Solvent-based epoxy primer, two components  

Advantages:

  • High permeability should be able to link inside the material deeply
  • Linking well with all material surfaces, including metal surfaces.
  • Improve the aesthetic and materials savings for next coating.
  • Alkali resistance and high corrosion resistance
  • Easy to apply by popular tools such as brush, roller, nozzle... 
  • Easy to apply and materials saving because of allowing time application is long.  
  • Level of consumption density is very low, so it should be economic and efficient.
  • Can be diluted with solvent to adjust the viscosity appropriate for each specific application cases.

Substrate requirement:

  • For strong absorption and soft surfaces: Apply at least 02 primer layers before coating BestCoat lines. For flat surface, solid and average roughness: Apply 01 primer layer. For hardener surface: Dilute BestPrimer EP701 with 10-15% of BestThinner SC01 before application. To achieve higher aesthetic and mechanical properties as required, surface should be applied at least 01 layer of BestPrimer and 02 layers of coating paint or self-leveling paint of BestCoat lines.

Substrate preparation:

  • Concrete floor shall be cure for minimum 28 days, compressive strength: ≥ 20 MPa, tensile strength: ≥  1.5 MPa. Concrete floor shall be impurities, solid, flat, dry (moisture content ≤ 4%), the impurities, crack, dust must be clean as required.

Mixing:

  • Two components A and B should be mixed thoroughly with mixer speed 300÷400 rpm.
  • The mixing time at least is about 03 minutes or longer untill materials is homogeneous as required.
  • Keep materials is about 10-15% minutes and mixing again before application.

Application:  

  • Applied by a roller, a short brush or high pressure nozzle
  • Note: Do not use materials which timed out applying and begin curing. Application area should be cool and application instruction should be downwind. Do not smoke during applying.

Cleaning:

  • Clean tools, equipments with clean BestThinner SC01 before product hardening

Safety:

  • Both of two components are hazadous, flammable, therefore, they are required to be placed distant from heat or fire during the execution or preservation. This product can cause allergic to skin, therefore should be prevented from directly skin contact. Should wear gloves, masks and glasses while handling the product.
  • In case of accidental eye contact, wash with fresh water and seek medical advice immediately. Keep away from fire, spark and heat sources when application.
