Abstract
NanoSonic has designed, physically demonstrated, and delivered high performance pressure sensitive adhesives (PSA) to the Navy that may enable laminate based paint replacement systems for current and future fixed wing aircraft and rotorcraft. NanoSonic’s “Paint-it PSA®” is offered to NSMA / NAVAIR SBIR as a cost effective (< $5/lb.), repositionable, aerospace PSA with high peel strength (8 lbf./in.) over a wide service temperature range (-65°F to 285°F) for 1000 hours of continuous service. Synthetic engineering resulted in an advanced organic/inorganic hybrid system with an in-situ primer that does not require added tackifiers. The viscoelastic PSA chemical compositions were tailored for cryogenic elasticity, high temperature stability, and minimized creep compliance. A novel ultra-hydrophobic, chemically inert, copolymer modifier was also developed for enhanced durability and long term moisture and solvent resistance. NanoSonic shall work with a defense prime to complete the contractor’s required PSA Test matrix testing to demonstrate a TRL 7-8 for Paint-it PSAs. We shall demonstrate the ability to simplify the process of bonding an extruded polymer film onto primed and primed/topcoat military aircraft systems, followed by removal of such laminates without residue or damage to the aircraft for facile paint replacement/repair appliqué films that will meet NAVAIR flight qualifications.
