PEELABLE SURFACE COATING SYSTEM OVER MULTI-SECTION SUBSTRATE

摘要

A peelable surface coating system comprises a multilayer peelable surface coating adhered to multi-section substrate with joints between sections. The multilayer peelable surface coating has strength and flexibility layers and a wear layer. Each strength and flexibility layer has a thickness of <0.6 mil and a Konig hardness of < 40 seconds. The wear layer has a Konig value of >60 seconds and a thickness of from 0.2 to 3 mils. The strength and flexibility layers have a combined total thickness of 3.3 to 6 mils. The peelable coating system spans joints between sections and is peelable from both the substrate and the joints, and has an elongation (E%) of > 350%, a break force maximum load (BF gm-Force) of > 3000 gm-Force, a total thickness (T mils) of from 3.5 to 10 mils, and wherein: (E %) x (BF gm-Force) x (T mils) > 4 x 106.
