It should be noted that each yankee operates at di ff erent temperatures depending on the requirements of the paper mill. If a slightly lower temperature is required, then the coating T g should be slightly reduced by the addition of the release in a controlled way. For this reason, it is preferable that the temperature range of the product is not so wide in order to easily achieve subtle changes in the T g of the polymer when it is required [31,33].
