An adhesive film that transmits 99% of incoming light helps a maker of laminated windows for the International Space Station meet stringent optical clarity specs. The Optically Clear Laminating Adhesive 8141 from 3M, St. Paul, has a scant 0.1% haze level and is free of common defects such as bubbles and dirt because it’s manufactured in clean rooms. It also withstands the elements without delaminating or yellowing.
Eyesaver International Inc., Hanover, MA, uses the film to attach a clear “scratch pane” to the inner surface on Space Station windows. The scratch pane protects the 0.5-in.thick windows from damage, keeps shards out should a window shatter, and provides a substrate for transparent, conductive, thin-film heaters.
“The 3M product has excellent uniformity, creates zero optical distortion, and coats flat without voids,” explains Eyesaver’s Steve George. “Station builder Boeing says it’s clear enough to photograph through,” adds partner Matthew Smillie.This entry was posted in Uncategorized.
