Abstract: A composition for a Coating System (paint) which forms an insulating material being designed to both reflect infrared radiation and have reduced thermal conductivity. The coating system may be either a single Thermal Coating or may be a Thermal Coating used in combination with a Thermal Primer. The Thermal Coating is formulated using conventional techniques and a resin used in paint manufacture, but utilizes primary pigments and extender mineral pigments which preferentially reflect in the infra red area of the solar spectrum. A method of characterizing particulate materials for their infra red reflectivity is described, which provides a means for preferential selection of particulate additives based on their relative visible light and infrared reflectivity. Additionally the incorporation of hollow micro-spheres is desired to reduce thermal conductivity.

Abstract: A method of producing a breathable film which comprises the steps of: (a) producing an inorganic filler by treating particles of an inorganic particulate material comprising an alkaline earth metal carbonate compound by reaction with a hydrophobising surface treatment agent comprising one or more aliphatic carboxylic acids having at least 10 chain carbon atoms to produce a hydrophobic coating on the particles under conditions such that the inorganic filler produced has a total surface moisture level comprising moisture adsorbed on the particles and trapped within the hydrophobic coating thereon of not greater than 0.1% by weight based on the dry weight of the inorganic particulate material; (b) producing a filled thermoplastic composition by mixing the inorganic filler produced in step (a) with a heated thermoplastic polymer; and (c) shaping the composition produced in step (b) by heat processing to form a film product.

Abstract: A granule containing a high proportion of a mineral filler and a colorant pigment system in a thermoplastic binder, for blending with an end product thermoplastic in which the mineral filler and the colorant pigment is to be dispersed. The granule comprises 85% to 92% by weight of the granule of mineral particles, which is coated with one or more fatty acids having a carbon chain length of from 12 to 20 carbon atoms and the colorant pigment. The colorant pigment may be inorganic or organic or a mixture thereof. The balance of the granule by weight comprises a thermoplastic polymeric binder. The particle size distribution of both the mineral and the colorant particles is in accordance with the optimum particle packing equation to optimize packing of the particles in the granule. The ratio of mineral to colorant pigment to binder may be about 75:15:10 or about 0.1:89.9:10. The invention includes a granule with only a colorant pigment system.

Abstract: A thermoplastic granule containing a high proportion of a particulate carbonate filler in a thermoplastic binder, for blending with an end product thermoplastic in which the carbonate filler is to be dispersed. The granule comprises at least 85% by weight of a particulate carbonate which is coated with one or more fatty acids having a carbon chain length of from 12 to 20 carbon atoms. The balance of the granule by weight comprises a thermoplastic polymeric binder which is solid at ambient temperature and is compatible with the end product thermoplastic in which the carbonate filler is to be dispersed. The polymeric binder is an amorphous polyolefins and/or a highly branched polyethylene wax. The PSD of the carbonate is selected to maximize packing.
