ABSTRACT:
A sealant is provided that possesses many or all of the characteristics of conventional thread sealants, and allows application with improved smoothness and uniformity of application. Sealants in accordance with the invention utilize engineered fibers such as melamines like Basofill and polyaramids such as Kevlar in its composition. Engineered fibers offer consistency and uniformity that other previously used sealants lack. Engineered fibers can improve the gap filling characteristics of the sealant, as well as the resistance of the sealant to chemicals and high pressures. Engineered fibers tend to have very high strength and low density.
