Release Coating Agent
report_problem Problem Statement
Silicone-based release coatings dominate the pressure-sensitive adhesive label, tape, and composite molding industries but are permanent environmental contaminants that interfere with downstream recycling, painting, and bonding processes. Silicone contamination (as low as 0.1 ppm) causes fish-eye defects in automotive painting and adhesion failure in bonding applications. A bio-based release agent using naturally-derived compounds could provide controlled release force without persistent silicone contamination.

flag Success Criteria
Achieve stable release force in range 5-40 cN/inch tunable by crosslink density, release force drift <20% after 7-day aging at 70°C, subsequent PSA adhesion ≥90% of original (no contamination), and zero silicone detection by ATR-FTIR on adhesive surface
precision_manufacturing Equipment Needed
Mayer rod coating set, lab oven with precise temperature control, 180° peel tester (e.g., Instron with peel fixture), coat weight measurement (analytical balance + known area), ATR-FTIR spectrometer, standard PSA tapes for testing, supercalendered kraft paper, PET film, aging oven, bio-based waxes and fatty acid esters
