Abstract
An improved magnetic sealant is disclosed wherein the improvement comprises the introduction of magnetizable particles having a particle size of about 150 microns or larger into the resin. It has been found that the larger particle sizes allows for the introduction of increased amounts of magnetic particles into the resin without the loss of flow properties. This results in a sealant which will have strong magnetic properties but will be an effective sealant for irregular surfaces as well as smooth ones. Also disclosed is a method for making the sealant and a method for using it.
