After 10 years of fighting with my Pearson's 3/16" safety
glass which isn't available anymore, having mildew growing between the layers, cracking when reinstalling, I have a new plan...
I want to bond 1/2" Lexan
directly to the exterior aluminum
frames with 3M's VHB, a double sided acrylic
tape. It comes in various thicknesses and widths and is supposed to be water
and UV resistant.
Due to the expansion of the Lexan
, I am still considering what sealant to create a bead around the exterior edge of the Lexan.
Currently considering 3MTM OEM Polyurethane
Glass Adhesive Sealant 590.
I will paint
a border around the inside of the Lexan with possibly POR-15, but I need to do more research
on what paint
bonds to Lexan. I just don't want to see the beige VHB through the Lexan.
