POLIBRID® 670S is a solventless two component, organo-silane modified, amido-amine epoxy primer designed specifically for applications of POLIBRID solventless elastomeric polyurethane coatings and linings to carbon steel or concrete substrates.
POLIBRID 670S utilizes the most advanced technology in moisture-tolerant, flexible epoxy resins, producing tenacious adhesion to the substrate while creating a strong chemical bond to the Polibrid elastomers. Its superior moisture tolerance serves as a barrier to substrate moisture that allows application of the POLIBRID elastomeric polyurethane coating and lining materials over dry or damp concrete surfaces. The use of this primer to damp or wet metallic surfaces is not recommended.
POLIBRID 670S is topcoated with the POLIBRID elastomers after it sets up firm, but while still in a tacky condition, using "wet-to-wet" application techniques that enhance adhesion and increase productivity. POLIBRID 670S does not contain tars, lead, zinc or chromates and complies with all known VOC emissions standards.
POLIBRID 670S is highly recommended for application to concrete substrates, especially damp surfaces such as those found in pump stations, manholes, cooling tower basins, secondary containment installations and other below-grade or at-grade structures. It is also recommended for application to metallic substrates when surface profile requirements for application of the POLIBRID elastomers direct to metal cannot be achieved. Call your regional technical service representative for specific recommendations.

ROLLER |
|
| Use roller suitable for solvent base materials. Nap length will depend on the roughness of the substrate. | |
|
BRUSH |
|
| Distribute evenly using full brush strokes. | |
| Recoat Window | For optimum results, topcoat before fully dried to the touch. Primer must be free of dust, moisture, condensation and contaminants before topcoating. If primer dries hard to the touch before topcoating, application of an additional coat of primer is recommended. |
| Mixing | Before using, agitate both components in their original containers for 5 minutes to produce complete suspension. Measure components at precise 1A:1B volume ratio, pour into clean separate container and blend by agitating mixed components for 5 additional minutes. Do not apply primer that has exceeded its usable pot life. |

Allow a minimum 28 day cure period for new Portland Cement ASTM Type 1 concrete. Decontaminate per ASTM D-4258. Abrasive blast clean per ASTM D-4259 to remove laitance, loose concrete, existing coatings, and to produce surface profile resembling coarse sandpaper. Waterblasting alone or acid etching are not acceptable. Repair all leaks as directed by Engineer and eliminate standing water. If necessary, resurface with high-strength, rapid-curing, zero-shrinkage resurfacing product, before primer application. Concrete must be free of dust and contaminants prior to primer application.
AVOID SKIN CONTACT! Wear chemical goggles as minimum eye protection, use impermeable gloves and cover all exposed skin. Do not allow contaminated clothing to contact skin. Use properly fitted organic vapor respirators and adequate ventilation. Wash hands before eating, smoking or using washroom. Follow precautions in CFR Title 29 (OSHA) and all pertinent local, state & federal health, safety and environmental regulations. Read, understand and fully comply with recommendations made in Material Safety Data Sheets (MSDS) supplied for individual coating components!
COMPLY WITH PERTINENT OSHA REGULATIONS RELATIVE TO WORK IN CONFINED SPACES! Provide forced air ventilation. Workers must use carbon monoxide filtered breathing air-line respirators. If flammable vapors are present, use only non-sparking tools and equipment.
SKIN CONTACT: Wash thoroughly with plenty of soap and water.
EYE CONTACT: Immediately flush with fresh clean water for at least fifteen (15) minutes and get specialized medical attention promptly.
INHALATION: Remove to fresh air and provide oxygen.
INGESTION: Immediately call a physician or poison control center. DO NOT INDUCE VOMITING!
