I am working on an acutal project. We have a product (polyurethan silicone, which already is in use) with an unknown VOC content. Neither in the Data sheet we got any informations and after consulting the maunfacturer. We have to conduct also the budgeting method. Therefore it is important, to know how should i go on. What possibilities did we have?
Thank you

For the quantity,you will need to estimate based on material coverage and if you can find a similar product that provides a coverage guide for the adhesive.
For the VOC level, I would attempt to find 3 similar products, average them and use that for your VOC estimate.
Then, as stated in the FAQ's above; Is there a shortcut to the VOC budget method if you have just one product that is used minimally on a project?
Yes, if you have just one non-compliant product, then you can balance it out with just one really good, low VOC product, as long as all your other products meet the requirement. For example, if you have two gallons of non-compliant adhesive that is 100 g/L over its required threshold, then you can balance it out with enough compliant product where you show you are at least 100g/l under the required threshold, thus balancing the VOC budget.
