DUOTACK SPF Adhesive is a low pressure, two-component spray polyurethane foam adhesive. It is specifically formulated by SOPREMA for adhering SENTINEL® HFB PVC membranes to approved substrates as well as adhering insulation and coverboards to approved substrates or together. When using DUOTACK SPF Adhesive products, there are some temperature considerations to take into account. In this blog post, we will address these temperature constraints and tips for a successful application.
Tip #1: The Storage Temperature Requirements
When storing DUOTACK SPF Adhesive, it is important that the product is stored in a dry environment and is left in the original packaging. The product should not be stored in direct sunlight or near heat sources. It should also not be stored in a cold area or where the product could freeze. The storage area temperature should fall between 50°F-80°F (10°C-27°C).
Tip #2: Application Temperature Requirements
Prior to application, the product must be conditioned so it reaches a temperature between 70°F-90°F (21°C-32°C). Keep in mind, that conditioning may take up to 24 hours to ensure the chemical has reached optimal application temperatures.
Tip #3: How to Condition the Product
To condition the product, store in a controlled environment with desired temperatures prior to application to ensure proper application temperatures. It can take up to 24 hours for the material in each tank to reach the required application temperature. Building and placing tanks into a hot box is an option, but requires more than a few hours of exposure.
Tip #4: What Happens if Material is Applied Outside the Desired Application Temperature Range?
If temperature guidelines are not followed and the product is applied outside of the desired range there are a few issues that can occur. First, the viscosity of the A and B components will be affected and it can result in an uneven mix of each component. If the ratio is off, the strength of the adhesive will be compromised. It is also possible that the tanks will not empty at the same rate, resulting in less coverage throughout the project.
By following all temperature and application guidelines, DUOTACK SPF Adhesive should provide you with up to 50% more coverage per kit than the competition. It will also yield time and labor savings due to a faster flow rate that will allow for quicker installation process.
