EnviroSEAL sealants are engineered to remain liquid and inert until exposed to pressure differential and positive displacement through a point of  convergent flow.  Velocity profiles then create shearing forces against the sealant which disrupts the stability of the fluid passing through the site of the opposing differential force.  At a precisely controlled shear velocity through a leak site, sealant will quickly transform from liquid to solid, adhering tenaciously to the walls of the leak.  As transformation progresses, the seal forms a strong ultra-dense fibril network that completely fills the leak.  This seal remains  flexible, inert, solid and strong and will completely penetrate and fill the entire leak channel. Since the magnitude of shear can easily be controlled by the rate of flow through the leak, we can precisely control the point at which seal formation will initiate. EnviroSEAL and MicroSEAL resins build strong, tenacious, flexible, and inert seals that can withstand pressures in excess of 20,000 psig and temperatures beyond 550°F.   Any remaining sealant in the line will not block, plug, or interfere with the system, provides corrosion protection, and can be used in any fluid system regardless of type; oil, glycol, or water.
