Process for restoring discarded silicone-polycarbonate parts. |
摘要 |
A process is provided for reclaiming rejected polycarbonate articles, such as an automotive headlamp-lens having a thermoplastic acrylic primer and a defective silicone hardcoat. The silicone hardcoat can be selectively removed with an aqueous alkaline bath treatment. The treated polycarbonate article can be recovered with the thermoplastic acrylic primer remaining substantially intact; the article can be restored by treatment with a silicone hardcoat. |
