Chemicals PLASTIC & RUBBER INSTANT ADHESIVE 1OZ

We had to switch to PR100 when Loctite discontinued the adhesive we were using to bond E-Laminates together for use in electromagnetic device. It performs wells but does require 24 hour cure before handling and processing. Recently, we had issues with the adhesive not performing. We had to throw out a half pound. Discovered the PR100 is good for 30 days or less once opened to air when stored between 60 to 80 F with Humidity below 10%. During the evening and weekends, plant temperatures are above 80 F during warmer months. The warmer months is also the rainy season and Humidity can reach 45% or more. We are switching to the 1 ounce (20g) bottles to prevent the "spoilage" of the PR100. We also discovered that production was pouring adhesive into smaller bottles because the 1lb bottle was too difficult to work with. Switching to the 1 ounce (20g) bottles, eliminates purchasing and warehousing small bottles and the labor to fill the bottles. We already store our adhesive under refrigeration and would strongly recommend it if you are buying this product in bulk.
