摘要 |
A matrix is used to prepare a mold of an elastomeric material. A polymerizable compound is coated onto a flexible, thin substrate such as Mylar and is placed with compound side in intimate contact with the mold. The compound is cured and is bonded to the substrate. The cured combination is stripped from the mold and is given a metallic coating to improve reflectivity. A clear plastic coating may be applied to protect the metal surface. |
