- Addition and Dosage
The optimal amount of PAT-ADD AF 75 to be used is system related, but generally is between 0,2 and 0,5 % PAT-ADD AF 75, calculated on the total weight of formulation. Appropiate incorporation conditions have to be provided; prefered is premixing Pat-Add AF 75 with the unsaturated polyester resin. Suitability and optimum concentration to be used depends on the individual requirements and conditions and is best checked experimentally.
