Description

Mr. JO Primer – AS is a two-part, solvent-free epoxy primer. It is flowable and non-porous. So, it is easy to apply. Moreover, it controls electrostatic charge with resistance up to 10⁹ Ohms. As a result, it forms a smooth and strong base for flooring. Additionally, it enhances safety in sensitive areas.

  • Color: Black
  • Pot life @25°C: 90-120 mins
  • Mixing Ratio: 100:30 PBW
  • Mixture consistency: Thixotropic paste
  • Electrostatic dissipating properties
  • Coverage: 4 m2/kg
  • Optics: Opaque
  • Data center
  • Semiconductor fabrication industry
  • Military & aerospace industries
  • Antistatic coating
Surface Preparation
  • Surfaces should be freed from laitance and dust by sand-blasting. In case sand blasting is not possible, thorough abrading with a hard wire brush should be preferable.
  • Suitable degreasing agent should be used to remove any grease, oil or traces on the surface.
Application Method
  • Mix the two components together thoroughly for at least 2 minutes so as to achieve uniform mixing and thorough consistency of the mix. Apply the mix using brush or spatula to the pretreated surfaces.
  • Allow 4-5 hours for surface to dry and 24 hours to achieve full strength.

Q1. What is MR. JO Primer – AS used for?

A1. MR. JO Primer – AS is a black, antistatic epoxy primer used as the base layer in electrostatic dissipative (ESD) flooring systems. It is essential for:

  • Preventing electrostatic buildup
  • Ensuring conductivity in antistatic epoxy floors
  • Providing a grounded base for subsequent ESD topcoats
Q2. Where is MR. JO Primer – AS typically applied?

A2. It is used in areas where electrostatic control is critical, such as:

  • Electronics assembly areas
  • Server rooms and data centers
  • Cleanrooms and laboratories
  • Explosive or flammable processing zones
Q3. What is the mixing ratio of MR. JO Primer – AS?

A3. The mix ratio is 100:30 by weight (resin : hardener). It must be mixed thoroughly to activate its antistatic performance.

Q4. Can this be used with regular epoxy topcoats?

A4. No. Primer – AS is specifically designed to be used underneath antistatic or conductive epoxy topcoats. Regular topcoats will negate the ESD properties.

Q5. How do I apply MR. JO Primer – AS?

A5.

  1. Ensure the concrete is clean, dry, and properly grounded (if required)
  2. Mix resin and hardener (100:30 PBW) thoroughly
  3. Apply using a trowel
  4. Allow to dry to a uniform matt finish before applying topcoat
  5. Avoid pooling or shiny areas
Q6. What if the surface appears glossy or has shiny patches after application?

A6. Shiny spots indicate non-uniform surface resistance. These must be:

  • Lightly sanded or abraded with fine-grit sandpaper
  • Cleaned before proceeding to apply the antistatic topcoat This ensures consistent electrostatic dissipative performance.
Q7. What is the finish and appearance of MR. JO Primer – AS?

A7. It cures to a black, matt-finish surface. Shiny spots must be corrected to avoid localized failure in conductivity.

Q8. What is the coverage and pot life?

A8.

  • Coverage: ~3–4 m²/kg depending on surface profile
  • Pot Life: ~40–50 minutes at 25°C
  • Recoating Time: 6–8 hours or once surface is touch-dry
Q9. How does MR. JO Primer – AS help in achieving ESD compliance? A9. It ensures:
  • Continuity between the ESD topcoat and the grounded substrate
  • Even electrical resistance across the flooring system
  • Reduction in electrostatic charge generation and retention
Q10. Can this primer be tested for conductivity?

A10. Yes. After curing, you can use a surface resistance meter to check for appropriate resistance values. Ensure contact points and grounding are in place before testing.

Q11. How should it be stored?

A11.

  • Store in cool, dry, sealed containers
  • Keep away from direct sunlight and moisture
  • Shelf life: 12 months unopened
