ACID RESISTANT PHENOLIC EPOXY RESIN
PRODUCT DESCRIPTION
A 100% solids, two component phenolic epoxy resin designed for concrete restoration and protection in extremely chemical corrosive environments. PC-1405 resin and curing mechanism is based on the same polymer chemistry as PC-555 Chemliner, providing the highest chemical resistance of epoxies available today. PC-1405 has excellent chemical resistance to acids, caustics, salts, aromatic and aliphatic solvents.
PRODUCT FEATURES
1. Excellent resistance to acids, alkalis, salts,4. Can be troweled, squeegeed, or rolled.
most industrial chemicals and many solvents.5. Will cure in damp conditions.
2. Extremely tough and high wearing properties.6. Cold temperature cure-down to 35°F
3. Excellent abrasion and impact resistance.7. Fast set - 4-5 hours for foot traffic

PRODUCT USES
Recommended as a resin for epoxy mortars or Epoxy toppings for restoration of concrete floors, sumps, drainage ditches, loading docks, tanks, ramps, storage silos, pump pads, and other concrete structures subjected to extreme chemical attack. PC-1405 is used frequently in secondary containment areas as a rolled on coating as well as a trowel down system. PC-1405 is used as a resin with fiber glass reinforced systems; for exterior use and other floors with movement and vibration.
Ideal for most type services in chemical processing plants, pulp and paper mills, sewage and waste water treatment facilities, fertilizer plants, petroleum refineries, electric generating stations, coal handling operations, food processing, etc.
SURFACE PREPARATION
GulfCoast Paint Mfg., Inc. recommends four types of surface preparation. Any one of the four surface preparations may be sufficient or a combination of the four may be required depending on the condition of the concrete surface.
1. HighPressureWetAbrasiveBlastCleaning
All loose and unsound concrete must be mechanically removed down to sound concrete by means of power tool equipment, such as chipping/scaling hammers, rotary scalers, etc. High pressure water blast with sand injection all surfaces to remove all concrete laitance, contaminants, and other foreign deposits to provide a sound, clean surface. Use clean, dry air to blow down these areas to remove excessive moisture.
2. AcidEtch
Apply Gulf Coast Paint’s Clean & Etch Concrete Acid Solution at a spread rate of approximately 150 square feet per gallon. Work the solution into the concrete with a stiff broom or fiber brush. Allow solution to remain on the concrete surface for approximately 10 minutes, or until the effervescing and bubbling ceases. Then flush floor thoroughly with clean, fresh water to remove all laitance, dirt, and other foreign materials.
3. VacuumBlast
All areas of the existing concrete shall be Vacuum Abrasive Blast cleaned using a Wheelabrator Blastrac Shot Blast machine with Dust collector. A proper anchor profile pattern shall be achieved to provide maximum adhesion of the recommended system. A thorough washing may be necessary prior to blasting to remove all foreign matter. Check with Blastrac Mfg. for proper shot and application procedures.
4. DryAbrasiveBlast
Abrasive blast concrete surface to remove all laitance, loose concrete, coating, sealers, etc. It is necessary to achieve a rough anchor pattern and get to sound concrete. All blast material and foreign matter must be removed before application.
In all cases of surface preparation, the pH should be checked. A pH reading of 7.0 to 8.5 is acceptable. Also, a “Water Dissipation Test” should be made on random areas of the floor to determine that the proper degree of porosity has been achieved. A “Vapor Barrier Test” should also be run on the concrete. ConsultGulf coast Paint Mfg. for specifics on testing.

SURFACE PREPARATION - cont.
New concrete must be cured at least a minimum of 28 days before applying a coating. All laitance, efflorescence, chemical contaminants, grease, oil, and other foreign material must be removed. The prepared surface must be clean, dry and structurally sound.
MIXING INSTRUCTIONS
Do not mix until surface has been primed with PC-155 or PC-1702. Best results are obtained if both Base and Hardener are stored at or above 75F for 12 hours prior to mixing to insure normal viscosity.
Poly-Crete PC-1405 is prepared by mixing 2 parts Base (Part A) to 1 part Hardener (Part B) by volume with a power mixer for approximately 1-2 minutes. Slowly add aggregate while continuing to mix, until a uniform blend is achieved. Total mixing time should be 3 minutes. Small batches may be made in a KOL mixer. For large batches, use a Paddle Mortar (Plaster) mixer. Immediately after mixing pour material out of container and spread out on primed substrate.
APPLICATION PROCEDURE
PC-1405 must be applied over the PC-155 or PC-1702 while they are still tacky. Apply the aggregate filled epoxy mix by hand trowel, squeegee, or roller. Apply pressure to “compact” material to a dense, monolithic topping. PC-1405 can be squeeged for self-leveling and reinforced floors. For coating and linings, PC-1405 can be rolled.
CURE TIME
The aggregate filled epoxy mortar has an “open” time of approximately 20-30 minutes at 75F. Immediately after mixing a batch it should be placed and spread onto the surface to be protected. Highly filled “mortar” and “concrete” mixes will be ready for foot traffic in 4-5 hours. Self-leveling compositions will be ready for foot traffic in 6-8 hours and forklift traffic in 24-48 hours. For strong acid and solvent service, a 10 mil dry sealer coat of Chemliner PC-555 or PC-1500 Novolac coating is recommended. PC-500 and PC-517 are alternative sealer coats, depending on service requirements.
CAUTIONS
Poly-Crete PC-1405 is not a fire hazard; the flash point is 300F. However, under conditions of fire it will burn and release potentially toxic fumes. The Base portion is relatively inert physiologically. The Hardener portion contains amines and related materials. These can cause irritation and possibly chemical burns to the skin and eyes. This is also true for mixtures of Base and Hardener.
Wear safety glasses, gloves, and protective clothing when using Poly-Crete PC-1405.
This product is sold without warranty as to performance expressed or implied. Users are urged to make their own tests to determine the suitability for their particular conditions.
