Description
A two-part, thixotropic, polysulfide-based void filling material, PR-1448 has outstanding adhesion, minimal shrinkage, great low-temperature flexibility, and resistance to salt water, oils, grease, and fuels. It is a compound that effectively resists pressure and fuel, and when put under 6.5 psi of pressure at 160 °F, it does not flow or extrude. Gaps and recesses can be vertically filled thanks to the excellent non-sag qualities.
