Flexural Strength 4,990 psi Coefficient of Thermal Expansion 18 [(in.) x (in). x F)] x 10(3) Cure Time 24 hrs Recoat Time 10-12 min. Mixed Viscosity Putty Surface 1. Thoroughly clean the surface with Devcon Cleaner Blend 300 to remove all oil, grease, and dirt. Preparation : 2. Grit blast surface area with 8 - 40 mesh grit, or grind with a coarse wheel or abrasive disc pad, to create increased surface area for better adhesion (Caution: An abrasive disc pad can only be used provide white mesh is revealed). Desired profile is 3 -5mil, including defined edges (do not "feather epoxy). WORKING CONDITIONS: Ideal application temperature is 55o F to 90o F. In cold working conditions, heat repair area to 100 -110o F immediately prior to applying to dry off any moisture, contamination, or solvents, as well as to assist epoxy in achieving maximum adhesion properties. Mixing It is strongly recommended that full units be mixed, as ratios are pre-measured. Instructions : 1. Add hardener to resin 2. Mix thoroughly with screwdriver or similar tool (continuously scrap material away from sides and bottom of container) until a uniform, streak free consistency is obtained. INTERMEDIATE SIZES (1,2,3 lb. units): Place resin and hardener on a flat, disposable surface such as cardboard, plywood, or plastic sheet), Use a trowel or wide- blade tool to mix the material as in Step 2 above. Application Instructions: Spread mixed on repair area and work firmly into substrate to ensure maximum surface contact. Plastic Steel Putty (A) fully cures in 16 hours, at which time it can be machined, drilled, or painted. FOR MAXIMUM PHYSICAL PROPERTIES Cure at room temperature for 2.5 hours, then heat cure for 4 hours @ 200oF. FOR + 70oF APPLICATIONS Storage: Store at room temperature. Compliances: Non e Chemical Resistance : Chemical resistance is calculated with a 7 day, room temp. cure ( 30 days immersion 75oF)
