November, 2001

Description

Two-component, 1:1 ratio polyamide cured primer for use on clean and properly prepared metal or concrete surfaces. Offers excellent resistance to corrosion and exceptional adhesion to ferrous metal substrates. Resists solvents, dilute acids and alkali attack. Is suitable as use for protecting concrete substrates in secondary containment applications.

 

Prominent Features
  • ASTM B117 Salt Fog Resistance - 600 hours - No Effect
  • ASTM D522 Flexibility (conical mandrel) 1/8" pass
  • ASTM D3359 Cross Hatch Adhesion - 5
  • Dry Heat Resistance: 250°F continuous, 275°F intermittent
Uses

Sewage Treatment Plants, Paper Mills, Aluminum, Marine, Plating Facilities, Iron, General Corrosion Environments, and Fuel Storage Facilities

Limitations

Will not cure when temperature is below 50°F. Do not apply when rain is expected, relative humidity is greater than 90% or pH of surface is greater than 10. Most high gloss enamels become slippery when wet. To ensure maximum safety on horizontal surfaces, a small amount of sand or pumice may be added to give coating nonskid characteristics. All epoxy coatings will chalk and fade if applied on exterior surfaces subjected to direct sunlight. Where color and gloss retention are important, top-coating will be necessary. Will stain with prolonged exposure to brake fluid or in a kennel if exposed to animal waste. This staining will not effect the durability or protective qualities of the coating. Will not cure at surface temperatures below 50°F. Not for immersion service.

8 hour pot life. Will be less at higher temperatures. 30 minute induction period.

 

Surface Preparation

All surfaces must be sound, dry, clean and free of oil, grease, dirt, mildew, mill scale, form release agents, curing compounds, loose and flaking paint and any other surface contaminants.

NEW SURFACES:
CONCRETE AND MASONRY - All masonry surfaces must be allowed to cure a minimum of 30 days before painting. Acid etch or abrasive blast all slick, glazed concrete or concrete with laitance. For acid etching, follow all manufacturers directions and safety instructions. Rinse thoroughly and allow to dry. Prime concrete with 1 coat of an epoxy pre-primer.
STEEL AND FERROUS METALS - All direct to metal coatings provide maximum performance over near white metal blasted surfaces [SSPC-SP-10]. There are however, situations and cost considerations that may prevent this type of surface preparation from being done. ALLPRO coatings have been designed to provide protection over less than ideal surfaces. The recommended standard is a commercial blast [SSPC-SP-6]. The steel profile after the blast should be 1- 2 mils and be jagged in nature. Surfaces must be free of grit dust. The coating should be applied as soon as possible after the blast in order to prevent flash rusting or surface contamination. Hand tool cleaning [SSPC-SP-2] or power tool cleaning [SSPC-SP-3] can be used if blasting is not possible. In areas where adequate surface preparation is not possible, the use of an epoxy pre-primer is recommended. In highly corrosive areas where additional rust inhibitive qualities are required, prime with 1 coat of a zinc rich primer prior to applying Epoxy coatings.
GALVANIZED AND NONFERROUS METALS - Solvent clean all surfaces. Apply 1 coat of Vinyl Wash Primer.

PREVIOUSLY PAINTED SURFACES - Can be applied over old thermoset finishes in good condition. Test patches are recommended to check for wrinkling or lifting of existing coatings.

Application

MIXING: Mechanical mixing is recommended for best results. If mixing by hand, stir each component thoroughly with a separate clean paddle. Pour desired amount of Component A into a clean mixing container. Then add an equal amount of Component B into the container and stir thoroughly. Allow to induct for 30 minutes before using. Be sure to mix only an amount that can be used in 6 hours.

APPLICATION:Apply with brush, roller or spray. Do not thin if doing so would result in exceeding VOC limitations. Roll with 1/2" lambswool or 1/4" synthetic roller cover. Roll in one direction, rewet roller then cross roll.

Clean Up

Clean up immediately after use with an epoxy reducer such as Insl-X - TH0250.

Disposal

Contains solvents dispose of properly.

 

Caution

Technical Information

WARNING! FLAMMABLE LIQUID & VAPOR! HARMFUL OR FATAL IF SWALLOWED. SKIN AND EYE IRRITANT. HARMFUL IF INHALED. MAY AFFECT THE BRAIN OR CENTRAL NERVOUS SYSTEM CAUSING DIZZINESS, HEADACHE OR NAUSEA. CAUSES EYE, NOSE THROAT AND SKIN IRRITATION. MAY BE HARMFUL IF ABSORBED THROUGH THE SKIN. CONTAINS GLYCOL ETHER, HIGH FLASH NAPHTHA AND XYLENE.

NOTICE: Reports have associated repeated and prolonged occupational overexposure to solvents with permanent brain and central nervous system damage. Intentional misuse by deliberately concentrating and inhaling contents may be harmful or fatal.

Keep away from heat, sparks and flame. VAPORS MAY CAUSE FLASH FIRE. Do not smoke. Extinguish all flames and pilot lights, and turn off stoves, heaters, electric motors and other sources of ignition during use and until all vapors are gone. Prevent build up of vapors by opening all windows and doors to achieve cross ventilation. USE ONLY WITH ADEQUATE VENTILATION. Do not breathe vapors or spray mist. Ensure fresh air entry during application and drying. If you experience eye watering, headache or dizziness or if air monitoring demonstrates vapor/mist levels are above applicable limits, wear an appropriate properly fitted respirator (see Code of Federal Regulations 42 CFR 84) during and after application. Follow respirator manufacturer's directions for respirator use. Close container after each use. Do not get in eyes, on skin or on clothing. Wash thoroughly after handling.

If spilled, contain spilled material and remove with inert absorbent. Dispose of contaminated absorbent, container and unused contents in accordance with local, state and federal regulations.

WARNING: This product contains a chemical known to the state of California to cause cancer and birth defects or other reproductive harm.

FIRST AID: in case of contact, immediately flush eyes or skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Get medical attention immediately. Wash clothing before reuse. Destroy contaminated shoes. If you experience difficulty in breathing, leave the area to obtain fresh air. If continued difficulty is experienced, get medical assistance immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. If swallowed, do not induce vomiting. Call physician immediately. In case of medical emergency, contact 1-800-424-9300.

USE ONLY WITH ADEQUATE VENTILATION
