The present disclosure relates to a method of reactivating the surface of an organic paint coating, a method of facilitating adhesion of a further coating to the organic paint coating, and a substrate having a reactivated organic paint coating. There is also disclosed a surface reactivation treatment for an organic paint coating. The reactivation method also facilitates adhesion of the organic paint coating to further coating(s) across a broad application window.

Surface reactivation treatment

The present disclosure relates to polymers which are cross-linked reaction products of a reactive siloxane and/or a polyisocyanate and/or a polyol, a polyamine and/or reactive coating capable of reducing the ability of ice to adhere to the surface of an object, in particular aircraft or other vehicles, methods of producing the polymers and their use in coating surfaces.

Ice adhesion reducing polymers

The present disclosure relates to an FPOSS prepolymer which may be reacted with a reactive coating or a polyisocyanate and/or one or more of a polysiloxane, a polyol, a polyamine and a reactive coating; an FPOSS polyisocyanate prepolymer which may be reacted with one or more of a polysiloxane, a polyol, a polyamine or a reactive coating; and an FPOSS siloxane prepolymer which may be reacted with a polyisocyanate and/or one or more of a polyol, a polyamine or a reactive coating to form cross-linked polymers capable of reducing the ability of ice to adhere to the surface of an object, in particular aircraft or other vehicles, methods of producing the prepolymers and polymers and their use in coating surfaces.

Ice adhesion reducing prepolymers and polymers

The invention relates to a coating system, in particular a coating system containing an organometallic layer which allows the selective removal of post coating layers from substrates without detrimental impact to their 'in-service' performance. The organometallic layer comprises (a) an organic polymer containing multi-chelating functionalities; and (b) a metallic agent which forms an organo metallic complex with the organic polymer containing multi-chelating functionalities and is located between an optionally coated substrate and at least one post coating layer of a coating system.

Coating systems

A method of electrostatic spraying of a polymer surface involves oxidation and treating the oxidized surface with a polyamine and an electroconductivity modifying agent which contains a mono-carboxylic acid of from one to 12 carbon atoms.

Composition and method for preparation of electro-conductive polymer surfaces

This invention relates to a primer composition for wood comprising a waterborne composition comprising polyamine and having a pH of at least 11.5 and a method of improving the bonding of wood with coatings such as electrostatic coatings, and adhesives using the primer.

Method and composition for priming wood and natural fibres

A method for modifying a substrate containing a natural polymeric material to improve its interaction with other materials, the method comprising: A) Treating the substrate containing the natural polymeric material with a modifying agent selected from the group consisting of organo-functional coupling agents and multi-functional amine containing organic compounds; and B) optionally exposing the substrate containing natural polymeric material with one or more treatments selected from the group consisting of: i) subjecting the substrate to extraction with a solvent to reduce the content of extractable materials associated with the natural polymeric material prior to or during treatment with the modifying agent; ii) treatment with a physical field selected from static physical fields, high-frequency alternating physical fields and combinations of two or more thereof either prior to, during or after treatment with the modifying agent; and iii) oxidation of at least part of the natural polymeric material prior to or during treatment with the modifying agent.

Treatment of natural polymer based materials and the products based thereon
