Abstract
NanoSonic would optimize our novel polyorganosiloxane and siloxane-urethane copolymers as high performance, residue free, pressure sensitive adhesives (PSAs) that would promote simple appliqu, films repositioning/removal from NAVAIR rotorcraft and fixed-wing surfaces. The proposed PSAs offer excellent adhesion (50 - 250 N/m as a function of crosslink density per ASTM D 903 180o peel tests with adhesive failure, hence, residue free) over a temperature range of -120oC to > 350oC. While acrylic PSAs offer good adhesion, the proposed copolymers offered herein are synthetically engineered to provide service over a wider thermal range with enhanced solvent resistance (sea water, jet fuel and solvents) and weatherability against UV and ozone. During Phase I, accelerated ageing studies will be carried out to verify peel and lap shear adhesion of > 5psi up to 1,000 hours. Additional ageing studies shall be carried out under cryogenic and elevated temperatures (-65 F to 285 F) and after soaking metal-to-applique peel specimens in boiling water and heated solvents. NanoSonic currently offers specialty adhesives in volumes up to 55 gallon drums and shall work with our defense prime partner to increase the TRL from 5 - 8 of our cost effective, roll-to-roll compatible PSAs for appliqu, films during Phase I and II.
