SYNTHESIS AND BEHAVIOR OF PROTOTYPE "SILENT PAINT"

BASED ON THE PRINCIPLES OF CONSTRAINED LAYER DAMPING, "SILENT PAINT" IS A TWO-LAYER COATING SYSTEM CAPABLE OF ATTENUATING NOISE AND VIBRATION OVER A BROD TEMPERATURE RANGE. THE DAMPING UNDERCOAT LAYER IS COMPOSED PRIMARILY OF A METHACRYLIC/ACRYLIC, SEMI-COMPATIBLE INTERPENETRATING POLYMER NETWORK IN LATEX FORM, WITH THICKENERS AND PRESERVATIVE ADDED. THE CONSTRAINING OVERCOAT LAYER IS BASED ON A REINFORCED EPOXY RESIN, AND EXHIBITS GREAT STIFFNESS. THE SYNTHESIS OF THE LATEX IPN IS SUMMARIZED, AND THE MECHANICAL AND DAMPING BEHAVIOR OF THE NEW COATING SYSTEM IS CMPARED TO SEVERAL MATERIALS INTENDED FOR USE AS NOISE AND VIBRATION DAMPING PRODUCTS. /DOT/
