Non-Skid, Non-Flammable Coating for Navy Applications
Abstract
We have prepared a series of hybrid additives and incorporated them into urethane and epoxy coatings that were applied on steel and aluminum substrates. The films were homogeneous, but with a high coefficient of friction. The resulting coating toughness was increased, as measured by the improved abrasion resistance, hardness and flexibility of the coating. Similarly, the oxygen index and smoke density properties of the coating were used to demonstrate improved fire resistance. Corrosion was measured by the Salt Fog test, and used to demonstrate that these additives inhibit rust formation and propagation . The addition of hybrids to the coatings provided some thermal stability to the system, leading to reduced thermal degradation at high temperatures (200 to 400 deg C). An engineering analysis demonstrated that the additives can be prepared at $1-$2/lb, well below the price of specialty additives like corrosion inhibitors and UV stabilizers.
