Abstract: A measurement system includes an atomizer, an impactor, a particle counter, and a discharge reservoir. The atomizer has a liquid intake port and a gas intake port configured to aerosolize a liquid received at the liquid intake port. The impactor has an inlet coupled to the atomizer and has a first output port and a second output port. The impactor is configured to separate droplets wherein those droplets smaller than a selected cut point are directed to the first output port and those droplets larger than the selected cut point are directed to the second output port. The particle counter is coupled to the first output port and is configured to count particles larger than at least one particle size cut point. The discharge reservoir is coupled to the second output port.

Abstract: An intumescent coating system and method therefor is disclosed for thermally protecting a substrate having a surface exposed to fire conditions. The coating system of the present invention is provided as having a having a first film layer which forms a rigid carbonific char foam having toughness and rigidity, and a second film layer which forms an insulative carbonific char foam having insulation properties. The two foam components may be separately provided in a laminate-type arrangement as, respectively, an inner coating layer coated and cured on the surface of the substrate to form an inner film layer, and an outer coating layer coated and cured on the inner film layer to form an outer film layer.

Abstract: An intumescent coating system and method therefor is disclosed for thermally protecting a substrate having a surface exposed to fire conditions. The coating system of the present invention is provided as having a first component which forms a rigid carbonific char foam having toughness and rigidity, and a second component which forms an insulative carbonific char foam having a density about half the density of the rigid carbonific foam to give insulation properties. The two foam components may be separately provided in a laminate-type arrangement as, respectively, an inner coating layer coated and cured on the surface of the substrate to form an inner film layer, and an outer coating layer coated and cured on the inner film layer to form an outer film layer. Alternatively, the two foams may be provided as being formed from components blended to comprise a single coating layer which is coated and cured on the surface of the substrate to form a film layer.

Abstract: The present invention is directed to a water-resistant, aqueous base-dispersible article which comprises a pulp-filled binder, one of which is an ethylenically unsaturated carboxylated (e.g. acrylic) polymer soluble in base, the other of which is water-resistant. Accordingly, the pulp can be water-resistant while the binder is base-dispersible or the converse can be true. Cellulosic and polymeric pulp are ideally suited for filling an base-soluble acrylic polymer. Water-soluble resins can be incorporated into the article for controlling the properties for special purposes. The method for forming such an article comprises yet another aspect of the present invention.

Abstract: The present invention is addressed to a curable, marine anti-fouling composition of a thermoplastic or thermosetting binder, solvent, non-tin, organo antifouling agent, and optionally conventional additives, e.g. leaching agents, opacifying pigments, etc. The anti-fouling agents are found in preferentially-concentrated domains (hereinafter, often referred to as "PCD") in the cured compositions. The PCDs can be termed non-homogeneous, phase-separated, or incompatible in the system. The art term used in describing the PCDs of anti-fouling agent is not limitative of the invention as the disclosure herein will demonstate. Preferably, PCDs are created by forming an oligomeric adduct of the anti-fouling agent which adduct is formed into PCDs upon the curing of the composition. Additional techniques for forming PCDs of anti-fouling agent are revealed herein.

Abstract: Disclosed is an improved marine anti-fouling coating composition of a thermoplastic binder, an organic solvent, a tin anti-fouling agent, a copper anti-fouling agent, and a water-soluble leaching agent. The improvement in can stability for said coating composition comprises the leaching agent being a water-sensitive, solvent soluble non-cross-linked polymer having an acid number of below about 50 and a .chi. value of between about 0.1 and 0.3; or a water-sensitive, solvent soluble, polymer having an acid number of below about 50 and a .chi. value between about 0.3 and 0.6. The water sensitive solvent insoluble polymer may be a non-cross-linked oligomer or polymer or a cross-linked hydrogel possessing the requisite acid number and .chi. value restriction.

Abstract: The invention relates to room temperature-curable, non-emissive, flame-retardant coating compositions. The main resin for the coating compositions is a flame-retardant polymer selected from an air dryable flame-retardant polymer, a room-temperature curable mixture of a flame-retardant polymer and curing agent therefor, and mixtures thereof. The solvent for the coating composition is selected from water, a liquid, curable, non-flame promoting solvent and mixtures thereof. The novel liquid, curable, non-flame promoting solvent comprises a liquid polyhalogenated organic ring compound substituted with an air-dryable group.
