COLD WEATHER ALERT FOR CANISTER & AEROSOL ADHESIVES

WHY AN ALERT?:
When adhesives get cold they get thicker. This thickening has an adverse effect on the adhesive’s sprayability characteristics. The adhesive in canisters and aerosol cans is pushed out by a compressed gas. When this gas gets cold it shrinks dramatically. This means we are now asking the gas (which now has less force) to push and spray the thickened adhesive in the same way that we are used to seeing. Improper sprayability can be expected.

PREVENTION:
Keep them warm. Storage at 21°C or 70°F is ideal. It is also good practice to keep canisters away from outside walls and off concrete floors as the concrete acts as a heat sink. Also, keep in mind that the eye level temperature reading on your thermostat is a lot higher than down at
ankle level where your canister is.

SOLUTION:
If your cans or canisters have gotten too cold to spray properly, just get them back to proper temperature, keeping in mind that the larger the canister, the longer it will take to get the interior up to temperature. Smaller containers can be submersed in hot water to speed up the warming process. If that is being done, periodically shaking or rolling the canister will bring the cooler adhesive in the center in contact with the warm metal of the canister. Another alternative are drum ‘heat belts’ that can be found at most industrial supply houses. These belts secure around the canister and provide constant supply of safe heat, if used according to manufacturers recommendations. For safety reasons, we suggest restricting heating to a maximum of 120 to 130oF, Never leave a cylinder being warmed unattended.

QUESTIONS:
Please contact the NorthStar customer service department or your adhesive sales person if you
have any questions regarding cold weather handling of your canister adhesives.
