POLIBRID 705 provides the ultimate in corrosion protection for concrete or steel in potable water service. Protects against microbiologically induced corrosion (MIC), making it ideal for municipal wastewater applications. Geotextile fabrics may be embedded within the coating to produce reinforced, bonded geomembrane linings. Suitable for a wide range of industrial applications, including:
- Potable Water Treatment & Storage
- Wastewater Treatment & Collection
- Crude & Fuel Oil Tank Bottoms
- Coal Bins & Hoppers
- Railcars & Tankers
- Mining & Metallurgical Plants
- Dam Gates & Trash Racks
- Secondary Containment Basins
- Hydroelectric Penstocks
- Pipelines (ID/OD)
- Pulp & Paper Mills
- Ship Hulls, Ballast Tanks & Decks
- Barge Hoppers & Decks
- Marine Pilings (Sheet/Tubular)
- Mixing
Mix Resin (Part A) with agitator for 30 minutes just prior to use. Catalyst (Part B) requires no agitation unless tinted.
- Surface Preparations
Concrete:
Allow 28 day cure for new concrete. Decontaminate per ASTM D-4258, then abrasive blast clean per ASTM D-4259 to produce surface profile similar to coarse sandpaper. Eliminate leaks and infiltrations and remove standing water. Resurface areas with excessive cavities (bugholes) or exposed aggregate using a high-strength, rapid-cure, zero-shrinkage resurfacing product. Wherever possible, geotextile fabric may be embedded within two layers of the coating to bridge, rather than resurface cavities, thereby eliminating the need for resurfacing compounds. Apply nominal 5 mils (125µ) POLIBRID 670S Epoxy Primer, before topcoating with POLIBRID 705. Concrete may be damp to the touch, however, surfaces must be free of condensation and visible moisture. Vacuum to dust-free condition before priming.
Carbon Steel:
For direct-to-metal applications, decontaminate surface per SSPC SP-1 "Solvent Cleaning" if needed, then abrasive blast clean per SSPC SP-10 "Near-White Condition" to produce a nominal 3 ½ mil (88µ) surface profile. Remove flash rust per SSPC SP-7 "Brush-Off Blast Cleaning". Substrate must be dry and dust free before coating. Application to wet surfaces is not recommended.
