Material Safety Data Sheets (MSDS) shall be available on site for all IECC products used during the tank lining process. MSDS's must also be made available for solvents and other potentially hazardous products used during the operation. 2.6.3 EnvirolineTM 125U must be preheated to 950-105°F prior to mixing.Using a mixing blade designed to IECC's specifications,mix thoroughly for 3 to 4 minutes,until color is uniform.Caution:do not over mix or shear the material.Mix at approximately 400-600 rpm.For best spray pattern,product temperature should be 105*-110°F. For severely pitted areas, add 2%xylene into mixed product, squeeze into the deep pits, then follow with applying the remaining coating to meet the required thickness. 2.6.4 Spray the entire interior surface of the tank to a minimum of 100 mils and a nominal thickness of 125 mils using an airless pump (45:1 minimum compression ratio). 2.6.5 One (1) unit of product covers approximately 41 square feet at 125 mils thickness. It may be necessary to mark off quadrants in 41 square feet sections to obtain the proper coverage at the desired thickness. Use a wet film scale to periodically measure the thickness during application. 2.7 Curing EnvirolineTM 1250 Lining 2.7.1 Allow 10-12 hours of curing time at 77°F and/or until a minimum Barcol Hardness reading of 70 or Shore D Hardness of 75-80 is reached. For tank temperatures less than 77°F, necessary time to ensure a complete cure may exceed 24 hours and/or until a minimum Barcol Hardness reading of 70 or minimum Shore D Hardness of 75-80 is reached. 2.7.2 When it is necessary to compensate for cold temperatures, post curing the lining is recommended, using a direct-fired portable air heater. Heat ambient tank air to 180-220°F, using a minimum 300,000 BTU air heater;place a flexible hose from the heater into the tank and direct the heated air toward both ends. Post cure a minimum of three (3) hours until a minimum Barcol Hardness reading of 70 gauge or minimum Shore D Hardness reading of 75-80 gauge is reached. 2.7.3 Eliminate any sources of flammable vapors in the work area if a heater is used to accelerate the curing process. 2/99 Page 12 of 30
