Applicant discloses a two part polymer mix for use in the aircraft industry that is applied with pneumatic mix and spray gun. The two part cartridge is used in the mix and spray gun so the mix is applied immediately upon mixing, but the two components are kept separated unless the gun is applying the mix. The mix cures to form a clear sealant that allows for inspection of cracks and corrosion beneath the sealant. It cures quickly so that the coated part may be further processed, for example in the assembly line during aircraft build.

The present invention concerns a process for continuously coating a cellulose-based fibrous substrate web with fatty acid chloride, comprising the steps of a) pre-drying a cellulose-based fibrous substrate web to an EN ISO 638:2008 dry matter content of less than 10%; b) coating the cellulose-based fibrous substrate web pre-dried in step a) with a liquid fatty acid chloride composition at a DIN EN 20187 relative humidity of less than 20 rH and a temperature below the boiling temperature of the liquid fatty acid chloride composition; c) thermally treating the coated cellulose-based fibrous substrate web obtained from step b).

Disclosed is a composition for a silica-based insulation layer including hydrogenated polysilazane or hydrogenated polysiloxzane, wherein a concentration of a cyclic compound having a weight average molecular weight of less than 400 is less than or equal to 1,200 ppm. The composition for a silica-based insulation layer may reduce a thickness distribution during formation of a silica-based insulation layer, and thereby film defects after chemical mechanical polishing (CMP) during a semiconductor manufacturing process may be reduced.

Hybrid pre-patterns were prepared for directed self-assembly of a given block copolymer capable of forming a lamellar domain pattern. The hybrid pre-patterns have top surfaces comprising independent elevated surfaces interspersed with adjacent recessed surfaces. The elevated surfaces are neutral wetting to the domains formed by self-assembly. Material below the elevated surfaces has greater etch-resistance than material below the recessed surfaces in a given etch process. Following other dimensional constraints of the hybrid pre-pattern described herein, a layer of the given block copolymer was formed on the hybrid pre-pattern. Self-assembly of the layer produced a lamellar domain pattern comprising self-aligned, unidirectional, perpendicularly oriented lamellae over the elevated surfaces, and parallel and/or perpendicularly oriented lamellae over recessed surfaces. The domain patterns displayed long range order along the major axis of the pre-pattern. The lamellar domain patterns are useful in forming transfer patterns comprising two-dimensional customized features.

A method of treating a polymer surface using conventional plasma nitriding, and a nitrided polymer surface obtained thereby. The method comprises introducing nitrogen into the polymer surface using conventional plasma nitriding, and optionally functionalizing the nitrided polymer surface with a molecule, such as an antimicrobial moiety, which is capable of forming a covalent bond with the nitrogen atoms within the polymer surface.
