Abstract: The present disclosure relates to a tie-coat composition comprising one or more binder polymers obtainable by copolymerizing a mixture of ethylenically unsaturated monomers, wherein the tie-coat composition provides a tie-coat with good dry adhesion, freshwater adhesion and saltwater adhesion to topcoats based on resins with condensable silane groups such as polydiorganosiloxane resins with hydrolysable groups or organic resins with terminal and/or pendant alkoxysilyl groups. The present disclosure further relates to a process for controlling aquatic fouling on a surface of a man-made object comprising applying such tie-coat composition and a topcoat composition, and to a substrate coated with a tie-coat layer deposited from such tie-coat composition and a topcoat layer.

Abstract: Fractal-like polymeric particles having a hierarchical, branched structure are disclosed. The particles have fibers with nanometer-scale diameters on their peripheries, which enables a number of unique and highly desirable properties. The particles are fabricated by a method combining phase separation and shear forces of different solutions, in particular a polymer solution. In addition, the particles may be used as coatings, nonwovens, textiles and viscosity modifiers and adhesives, among other applications.

Abstract: A method of manufacturing a structurally competent, EMI-shielded IR window includes using a mathematical model that combines the Sotoodeh and Nag models to determine an optimal thickness and dopant concentration of a doped layer of GaAs or GaP. A slab of GaAs or GaP is prepared, and a doped layer of the same material having the optimal thickness and dopant concentration is applied thereto. In embodiments, the doped layer is applied by an HVPE method such as LP-HVPE, which can also provide enhanced GaAs transparency near 1 micron. The Drude model can be applied to assist in selecting an anti-reflective coating. If the model predicts that the requirements of an application cannot be met by a doped layer alone, a doped layer can be applied that exceeds the required IR transparency, and a metallic grid can be applied to improve the EMI shielding, thereby satisfying the requirements.

Abstract: Provided is a carbodiimide-based, waterborne resin crosslinking agent that can improve the storage stability of a waterborne resin composition including a waterborne resin together with the crosslinking agent and further also improve the water resistance and the solvent resistance of a cured product of the waterborne resin. A waterborne resin crosslinking agent-containing liquid and a waterborne resin composition are prepared using a waterborne resin crosslinking agent comprising a hydrophobic polycarbodiimide compound and a water-soluble organic compound as blending components, wherein the water-soluble organic compound is one or more selected from the group consisting of an alkylene glycol-based compound, a water-soluble polymer other than the alkylene glycol-based compound, and a surfactant other than the alkylene glycol-based compound or the water-soluble polymer.
