Features & Benefits

Features

P-FDA is mixed 100 parts of Base to 10 parts of Activator by weight. Deviations from this ratio will cause changes in the physical properties. Choose a container with a volume that is four times greater than that of the rubber. Weigh the components accurately and mix thoroughly. Since there is no color, mix very carefully,scraping the sides and bottom of the container to insure that there is no unmixed portion. Place the container in a vacuum chamber and deaerate at 28 inches of mercury vacuum until the mass of rubber rises and then collapses
