PERMOX PCS-895
GLASS FILLED EPOXY-NOVOLAC
DESCRIPTION: A two component glass filled novolac coating for highly corrosive environments, designed for application where the presence of solvents is not permitted.
PCS-895 is essentially impermeable to most vapors; 20% of the volume of the cured film is laminar, high silica glass.
USES: For use where aggressive chemical and/or erosion resistance is required. PCS-895 may be used alone as a two- or three-coat system for concrete protection or in conjunction with fiberglass mat and/or aggregate blends depending upon the performance required.
SURFACE PREPARATION: PCS-895 is used where exceptional performance is required; very good surface preparation is required to achieve this performance.
Remove all grease and/or oil and other surface contaminants by solvent wash or steam detergent cleaning. : Failure to do so results in contaminants being driven into the concrete during abrasive blast cleaning.
The preferred method of preparation after cleaning and degreasing is shot blasting; however, abrasive blast cleaning is acceptable if all residuals are removed by vacuum prior to coating. : For both new and existing concrete, see our Technical Bulletin, CEMENT AND RELATED PRODUCTS PREPARATION FOR COATING.
The use of PCS-803 Grip-Tite Primer is recommended when conditions allow as it will both enhance adhesion as well as reduce the out-gassing of the concrete during the initial cure.
MIXING: PCS-895 is mixed 3 volumes of Base to 1 volume of Hardener. Mix all of both parts together with a power mixer (boxing is not adequate) until a uniform color is obtained. PCS-895 should be stored in a cool place. Shelf life is not seriously affected by storage up to 90oF but the pot life is shortened at elevated temperatures. To avoid material loss due to pot-life expiration, mixed material may be poured directly onto the surface area prior to spreading, which will improve the “working time” of the material.
APPLICATION: Short-nap roller, brush, squeegee, or trowel, depending upon the system and finish desired.
CLEAN-UP: REDUCER #76
CHEMICAL RESISTANCE: PCS-895 is resistant to contact with the following reagents for a maximum of 24 hours in splash/spillage service:
Sulfuric acid 85% Hydrochloric Acid 25% Nitric Acid 20% Acetic acid 25% Phosphoric acid 85% Citric acid 25% Sodium hydroxide 70% Sodium hypochlorite 10% Aqueous solutions of salt at all concentrations Toluene Ethyl alcohol Butyl alcohol Ethyl acetate Xylene
CAUTION: PCS-895 GLASS FILLED EPOXY-NOVOLAC hardener is corrosive. Components of this product, when combined, may be skin irritants and/or skin sensitizers. Rubber gloves should be warn to minimize skin contact. Practice caution and good personal cleanliness to avoid skin and eye contact. Avoid breathing vapors of heated material.
See material safety data sheet for full precautions prior to use.
If swallowed, do not induce vomiting. Call a physician immediately. For eye contact, flush with water; if irritation persists, seek medical attention. In case of skin contact, wash thoroughly with soap and water.
