Abstract
Automotive glazing represents a significant high volume application opportunity for engineering thermoplastic materials. Specifically, the use of polycarbonate can provide benefits such as vehicle weight reduction, occupant containment and design flexibility. Polycarbonate has superb impact resistance, optical clarity and the processing benefits of thermoplastic, but lacks abrasion resistance and weathering performance. Solution applied silicone-based hard-coats markedly improve the durability of polycarbonate. However, for glass-like abrasion performance, the use of plasma generated coatings is necessary in combination with the silicone hard-coats. A plasma-enhanced chemical vapor deposition (PECVD) process has produced coating systems with excellent adhesion, thermocycling performance, weathering and Taber abrasion similar to glass. Recent work has focused on the use of a hollow-cathode activated deposition (HAD) process, in order to produce similar performance coatings at much higher deposition rates than the PECVD process, for commercial viability.
