example 1

[0298] Example 1 Main seal with spacer

[0299] A thermal cure epoxy masterbatch was made using 96 parts by weight of Dow 431 epoxy novolac resin, 4 parts fumed silica, and 4 parts 2-ethyl-4-methylimidazole. 2 parts by weight of the spacer materials described below were added to a small portion of the above masterbatch. A small amount of this epoxy / spacer mixture was then placed on a 1" x 2" x 0.085" thick chrome-coated glass so that the epoxy mixture was in contact with the chrome reflector. The 1" x 0.085" ITO-coated A 1" x 0.085" piece of glass was placed on top and the glass interlayer was clamped so that the glass piece was lowered to the lowest point onto the spacer material. The element is then cured at about 180 degrees Celsius for about 15 minutes. Subsequently, once the element has returned to room temperature, look at the chrome and visually inspect the dent as if it were on surface 2.

example 2

[0300] Example 2 Primary Seal Material

[0301] Utilizing the heat cured epoxy of Example 1 with 140um glass beads resulted in a very severe visible dent pattern.

example 3

[0302] Example 3 Primary Seal Material

[0303] Utilizing the thermally cured epoxy of Example 1 plus plastic beads (Techpolymer, Grade XX-264-Z, 180um average particle size, Sekisui Plastics Co. Ltd., Tokyo, Japan) did not induce a visible dent pattern.

Abstract

A mirror includes an electro-optic mirror subassembly, and a thin-profiled bezel (344) attached around a perimeter of the electrochromic mirror subassembly. The electro-optic mirror subassembly is supported on a carrier (360) by an adheringly bonded heater (362) and foam tape (363) in a laminar arrangement. The bezel may be bonded to an edge of the front surface (312a) of the front element (312) of the electro-optic mirror subassembly, and / or may be bonded and / or interlockingly mechanically attached to an edge of the carrier. Alternatively, the bezel can be a strip of paint or thin coating material. The bezel can be molded in place, or can be pre-molded and elastically stretched to permit assembly. In one form, the bezel includes a laterally-extending fin that prevents seeing past the bezel into the inside of a mirror housing.
