  • Sprayable lightweight ablative coating
    Patent number: 5064868
    Abstract: An improved lightweight, ablative coating that may be spray applied and cured without the development of appreciable shrinkage cracks. The ablative mixture consists essentially of phenolic microballoons, hollow glass spheres, glass fibers, ground cork, a flexibilized resin binder, and an activated colloidal clay.
    Type: Grant

  • Cork-resin ablative insulation for complex surfaces and method for applying the same
    Patent number: 4204899
    Abstract: Cork-resin ablative insulation material is prepared in a form suitable for application to complex curved surfaces by mixing finely divided cork with a B-stage curable thermosetting resin, forming the resulting mixture into a block, B-stage curing the resin-containing block and slicing the block into sheets. The B-stage cured sheet is shaped to conform to the surface being insulated, and further curing is then performed. Curing of the resin only to B-stage before shaping enables application of sheet material to complex curved surfaces and avoids limitations and disadvantages presented in handling of fully cured sheet material.
