  • Marine anti-fouling coating formulations containing a soluble phase including a organotin polymer in combination with an insoluble phase including a crosslinked organotin polymer
    Patent number: 4599368
    Abstract: A coating composition for marine structures containing a soluble acrylic organotin polymer and a soluble metal-free acrylic polymer, in combination with an insoluble crosslinked organotin polymer, and an insoluble filler in a coating composition solvent can provide a tough, durable flexible coating and can provide extended protection to marine structures from the growth or accumulation of marine organisms.
    Type: Grant

  • Pile driving cap block cushion assembly
    Patent number: 4513828
    Abstract: An improved pile driving cap block cushion material is the subject of this invention. The material is a thermoplastic material characterized by being in particulate form, fiber filled (preferably glass fiber filled), having a melting point of 125.degree. C. or higher, a secant modulus of elasticity of from 50,000 to 800,000 p.s.i. and a coefficient of restitution of from 0.4 to 0.9. A number of thermoplastic materials are suitable for forming the material of the invention and include polyamides, polyesters, polyolefins, polycarbonates, polyimides, polyamide-imide copolymers, acetal homopolymers, acetal copolymers, fluoroplastics, polyphenyl oxides, copolyesters, polyetherimides, polystyrenes, polyvinyls, and polysulfones. A particularly useful group of materials is poly(ethylene terephthalate), poly(butylene terephthalate), nylon 6 and nylon 66. Additives such as antioxidants, heat stabilizers, reinforcers and colorants may also be added.
