We were approached by our rope coating customers to develop a coating for military use, which is now the main spec for military rope coating contracts known as Fiberlock. The Fiberlock extends the life, locks out dirt and sand and provides more slip, and provides a color coat for the rope.
**Fiberlock complies with United States Military Specifications.
The photo demonstrates a current US military specification for the construction of helicopter lifting slings. A sling is constructed from large diameter high tensile strength synthetic cordage with hand woven eyelets. Each lifting eye is first coated with our Purecast 603 semi-rigid casting polymer (black). Purecast was chosen for its excellent abrasion resistance on the primary contact points of the sling. Next, a rubber (75 shore A) neck of TrueKote CS 252 (black) is cast around the cord using a two-part, mold. The cast in place rubber provides additional abrasion and impact resistance around the eyelet base. All identifying numbers and specification information is cast into the rubber of each eyelet. The length of cordage between eyelets is dip coated in our Vinyl Rope Coating (green) to enhance abrasion resistance and color code each class of sling. The potted lifting eyes are constructed by using a 2 sided silicone rubber mold placed around the eyelet. The CS 252 is then mixed and poured into the mold surrounding the cordage when cured the eyelets are then removed from the mold.
Synthetic Rubber Coating
In partnership with Stewart & Stevenson defense contractors, Industrial Polymers was consulted to formulate a high build synthetic rubber coating to repair corroded floor panels of the worldwide FMTV tactical vehicle fleet. The vehicle cabs were originally constructed with a baked-on epoxy coating(e-coat) to protect the metal cab floors from rusting. In field use, the epoxy coating was quickly scratched away from sand and debris underfoot of vehicle occupants causing the carbon steel floors to rapidly rust away.
Industrial Polymers formulated fast gelation, high viscosity, high build, solvent-free, low odor, abrasion resistant flexible rubber coating, to repair these vehicles in theater around the world. A second fast cure coating with similar properties was developed for application on the manufacturing line to all new FMTV cab assemblies. Since 2000 Industrial Polymers has been the exclusive provider of elastomeric urethane coatings for anti-abrasion and acoustics on the United States family of medium tactical vehicles (FMTV) contract.
