A-1104 PLASTISOL PRIMER DESCRIPTION: A-1104 PLASTISOL PRIMER is a clear, air drying, thermo-setting primer for use with plastisols, organosols and vinyl fluidized bed coating. The resulting bond usually exceeds the cohesive strength of the plastisol. PROPERTIES: Color: Clear Weight per Gallon 7.24 lbs. Percent solids 14-16% Flash Point 44 deg. F. Average Coverage 720 Sq. Ft. (at .3 mil.) Viscosity 10 - 30 cps Brookfield 15 - 20 seconds (Zahn #2) THINNING: Make up any solvent loss (through evaporation) with QCM Plastisol Primer Thinner or methyl ethyl ketone. Always test before regular production run. Thin to original viscosity (see above). Too thick of a coating of primer may cause entrapment of solvent pockets (skinned over), which will case bubbling in the plastisol later, during cure. APPLICATION INSTRUCTIONS: Solvent-clean the metal with acetone, methyl ethyl ketone, toluene or trichloroethylene. Sand blasting or chemical etching is required only when mill scale or rust is present. Dip, spray or brush a thin film of the primer onto the part and allow to dry until free of solvents; approximately 60 to 90 minutes. After the primer has dried, apply the plastisol by conventional methods. PREHEATING When preheating the primed metal parts - CAUTION - do not overbake. Excessive heating of primed metal will destroy the action of most primers. Limit preheating to about 10 - 15 minute cycle @ 375 deg. F for optimum adhesion of plastisol to metal ( ideally preheat just enough to get metal primed metal parts to 375 deg. F). SAFETY PRECAUTIONS: Wear solvent-resistant gloves, protective clothing and chemical splash goggles when using this product. (Contains ketones) If contact with skin, wash with soap and water. Flush with water for 15 minutes. If contact with eyes, flush with water for 15 minutes. Consult physician. See MSDS. for technical assistance Dave.Musick@qcminks.com |
