UIG EVERSTORE ^® TRS – Vitreous Enamel Glass Fused-to-Steel Coating System

System No 1: Wet Spraying Slurry with 2-Coats & 2-Burns Process at 7-18 MILS DFT

NOTE: FOR TANKS WITH THE SAME COLOR ON THE INTERIOR & EXTERIOR SURFACES (Ex. White TITANIUM DIOXIDE TiO2 INTERIOR FINISH):

• A ground coat of milled Cobalt Blue Frit mixture with Nickel Oxide (NiO) shall be applied to both sides of the sheets plus to all four edges of the sheets and to the interior edge of the bolt holes and all shop-located and laser cut man-ways and tank nozzle openings.
1st Burn: Fire at 1600F

•A second coat of milled Cobalt Blue or other custom Top layer of glass coating color as required by the Owner or the Project Engineer to match the required tank colors shall be applied to both sides of the sheets plus to all four edges of the sheets and to the interior edge of the bolt holes and shop-located and laser cut man-ways and tank nozzle openings.
2nd Burn: Fire at 1450F

System No 2: Wet Spraying Slurry with 3-Coats & 2-Burns Process at 7-19 MILS DFT

NOTE: FOR TANKS WITH TWO DIFFERENT COLORS, SPECIFICALLY TITANIUM DIOXIDE (TiO2) WHITE INTERIOR FOR NSF61 APPLICATION & ANY OTHER COLOR ON THE EXTERIOR TANK SURFACE:

• A ground coat of milled Cobalt Blue Frit mixture with Nickel Oxide (NiO) shall be applied to both sides of the sheets plus to all four edges of the sheets and to the interior edge of the bolt holes and all shop-located and laser cut man-ways and nozzle openings.
1st Burn: Fire at 1600F

•A second coat of milled Cobalt Blue or Titanium Dioxide White (TiO2) glass as required by the Owner or the Project Engineer to match the required tank colors shall be applied to both sides of the sheets plus to all four edges of the sheets and to the interior edge of the bolt holes and all shop-located and laser cut nozzle openings and then dried.

•A third coat of milled Titanium Dioxide White (TiO2) glass shall be applied to the interior surfaces of the sheets plus to all four edges of the sheets and to the interior edge of the bolt holes and all shop-located and laser cut nozzle openings.
2nd Burn: Fire at 1450F

System No 3: Wet Spraying Slurry: 3-Coats & 1-Burn Process at 7-19 MILS DFT

NOTE: FOR TANKS WITH TWO DIFFERENT COLORS, SPECIFICALLY TITANIUM DIOXIDE (TiO2) WHITE INTERIOR FOR NSF61 APPLICATION & ANY OTHER COLOR ON THE EXTERIOR TANK SURFACE:

• All 6-sides shall receive a catalytic Nickel Oxide (NiO) pre-coat primer and then air dried.

• A second coat of milled Cobalt Blue or Titanium Dioxide White (TiO2) glass as required by the Owner or the Project Engineer to match the required tank colors shall be applied to both sides of the sheets plus to all four edges of the sheets and to the interior edge of the bolt holes and all shop-located and laser cut nozzle openings and then dried.

•A third coat of milled Titanium Dioxide White (TiO2) glass shall be applied to the interior surfaces of the sheets plus to all four edges of the sheets and to the interior edge of the bolt holes and all shop-located and laser cut nozzle openings.
One Burn Process: Cure Glass-Coating-System with a Single Burn at 1500F

NOTE:

As per AWWA D103-09 Section 12.4 Glass Coatings – Dry Film Thickness (DFT) of the interior and exterior coating should be minimum 6.0 mils and should not exceed 19.0 mils DFT. In no case dry film thickness (DFT) shall exceed 20mils (500 microns).
All plates with DFT over 20mils shall be rejected.

Glass Coating Characteristics:

• Acid and alkali resistant pH: 1-14

• Hardness: 6.0 (Mohs)

• Adhesion: 3,450 N/cm

Available Standard Tank Colors are Cobalt Blue or Titanium White
