Special Label Helps Avoid Cold Weather Problems

Cold weather can have adverse effects on aerosol products. For maximum performance using our canister adhesives, the temperature of adhesive inside the canister must be within an “optimal” range. But how do you measure that temperature? With ITW TACC’s patented Temperature Indicator Label. All mid-size and large returnable aerosol adhesive canisters produced by ITW TACC between November and March carry this special label. They are bright orange in color, easy to use and easy to read. Temperature Label Instructions explain where to find and how to read the Temperature Indicator Label.
One reason aerosols are affected by cold temperatures is its propellant. This hydrocarbon propellanta liquefied compressed gascan condense or thicken at colder temperatures, changing the ratio of adhesive solution and propellant being expelled. When this happens, spray pattern and consequently adhesive performance are adversely affected. Spray patterns affected by temperature variations range from slight spitting to streaming liquid, depending on degree and time of exposure to cold. A normal pattern will typically spray out “web-like” onto the surface.
Taking the following precautions can help eliminate potential problems:
- Store canisters and cans in a controlled environment between 60°F and 80°F.
- Keep canisters off cold concrete floors and away from outside walls .
- Allow both laminates and wood substrates to reach both moisture and temperature equilibrium for shop conditions. For best results, adhesive and materials to be bonded should be between 60 - 80F.
- If temperature is below 60°F,allow additional time for solvents and propellant to flash off.
Should the propellant condense or thicken, and above-mentioned symptoms are recognized, the problem can be solved by shaking aerosol cans vigorously until thawed or moving cans and canisters to areas heated above 70°F until thawed. To accelerate this thawing process, all except the 175 and 375 lb. canisters can be submerged in warm water for a minimum of 30 minutes and the problem should be solved. Once the containers and product return to a minimum of 70°F, the products will perform normally.
