Why is the glue between my cells yellowing?

The glue yellows then turns a yellowish-brown with time. This is normal and there's nothing we can do about it with the current qualified process. This process begins immediately and the speed depends on the amount of sunlight that the blind is exposed to. All PUR glues have this characteristic. In Arizona the yellowing will be noticeable within 3 months. In Maine or Northern Washington, it might not be noticeable for a year. But, the yellowing will occur.
