13 Drying of PL 50 P Film 60 Maximum film temperature while drying Temperature [ C] Entry of film into dryoff oven Dried film at the end of the dryoff oven Laminate immediately Laminate later , Minutes 3

14 K Waterbased Low Temp Cure Adhesive PL 50 P Strength Activate Green Strength: Cohesive Failure Substrate Failure Foam Tear Bladder Removal Edge fold release CURED CURING COOLING One minute One hour One day 4

15 Good Adhesion Requires: Surface Energy > 45 d/cm Substrate composition Pretreatment Surface contamination Heat Dry RT 50 C acceptable range 0 8% remaining water acceptable range (non-porous substrate) Activate C+ acceptable range OK to dry and activate in one cycle Coat weight Non porous substrate: 00 GSM wet - foil 00 GSM per side wet - rigid part 5

16 Robust Activation PL 50 P Performance at 70 C for Vinyl Skin to Spacer LOAD (N/m) REACTIVATION TIME (sec) 6

17 Robust Activation and Temperature Performance Capabilities of PL 50 P at Varying Temperatures for Spacer to TPO 80C 75C LOAD (N/m) C 70C REACTIVATION TIME (sec) 7

18 Application to Difficult Substrates Part type: Porous vs Non-porous PL 50 P total GSM for Skin to Spacer PL 50 P Total GSM for Spacer to TPO (N/m) 500 (N/m) Total GSM GSM This case shows how 50 P was successfully applied to difficult substrates, passing strict requirements 8
