A process of: providing a polyfunctional compound selected from polyisocyanate, polyacrylate, and polyepoxy; and reacting the polyfunctional compound with a hydroxyl- or amine-terminated silyl-containing compound. The polyfunctional compound and the silyl-containing compound are at least difunctional. A thermoset made by this process.

Degradable silyl-containing thermosetting networks

Disclosed is a composition having: an organosilane polymer, a polyamide polymer; and an abrasive aggregate. The organosilane is made by: reacting an amino-functional alkoxysilane with one or more polyisocyanates to form one or more adducts having an unreacted isocyanate group; and reacting the adducts with one or more polyfunctional amino- and/or hydroxyl compounds so that the polymer contains no unreacted isocyanate groups. The polyfunctional amino- and/or hydroxyl compound has a cycloaliphatic group or an aromatic group. The composition can be used to make a single-component polysiloxane non-skid/non-slip coating that is applied by rolling, spraying, or troweling and cures with atmospheric moisture.

Silyl-containing thermosetting networks and methods of degradation

An omniphobic material and its method of making by: providing an alkoxysilane-terminated polyurea, and reacting by a moisture-curing reaction the polyurea and a fluorinated material having one or more alkoxy or hydroxyl groups.

Moisture-curable omniphobic coatings

Silyl-containing alcohols and amines for thermosets that disassemble on-demand

Polyureas made from amino-functional alkoxysilanes, polyisocyanates, and polyfunctional amino- and/or hydroxyl compounds. The polyureas may be moisture-cured in a 1K system or be included in a 2K system with amino and epoxy or acrylate compounds.

Siloxane-based coatings containing polymers with urea linkages and terminal alkoxysilanes

A polysulfide coating composition includes an aliphatic, aromatic or cycloaliphatic material with at least 2 thiol groups; an aliphatic, aromatic or cycloaliphatic, acryl, polyester or polysiloxane-based material with at least two epoxy groups; and a catalyst. The coating provides a durable cavitation- and erosion-resistant coating for the rudders of ships, and is also suitable for sound-damping applications.

Rapid cure polysulfide coatings for cavitation resistance, erosion resistance, and sound damping

Moisture-curable single-component (1K) coatings based on N-substituted urea polymers with extended chains and terminal alkoxysilane groups. The coatings are highly flexible, are gloss retentive, provide fast tack-free and dry-through times, provide high solvent resistance, and provide excellent exterior color stability to sunlight. The coatings can be formulated to produce high-gloss, semi-gloss and low-gloss finishes, and thus have application as both commercial and military coatings.

Single-component moisture-curable coatings based on N-substituted urea polymers with extended chains and terminal alkoxysilanes

A composition having: an amine-functional compound and an alkoxysilane-terminated polyurea made by reacting: an amino-functional alkoxysilane-polyisocyanate adduct with a difunctional amino- or hydroxyl compound. The composition contains no unreacted isocyanate groups. A coating composition having: an amine-functional compound, an alkoxysilane-terminated polyurea, and an epoxy- or acrylate-functional compound. The coating composition is a two-component system.

Two-component siloxane-based coatings containing polymers with urea linkages and terminal alkoxysilanes

A nonskid/nonslip composition having: a mixture or a reaction product of an amino-functional polysiloxane and a non-aromatic epoxy, a polyamide polymer, and an abrasive aggregate.

Exterior durable siloxane-based nonskid/nonskip coating

The coating described herein attempts to provide this solution by synthesizing alkoxysilane-terminated N-substituted urea resins, then formulating them into moisture-curable single-component (1K) topside coatings. These coatings will provide greater external stability (to UV and visible radiation), cleanability, flexibility, cure times and lower VOC content than the currently qualified silicone alkyd topside coatings that are found on Navy ships. The single-component coating can include at least an alkoxysilane-terminated N-substituted urea resin, a reactive diluent, a pigment, a filler, and a catalyst. The resin can include an amino-functional silane substituted at the N-position and a non-aromatic isocyanate.

Single-component coating having alkoxysilane-terminated N-substituted urea resins

A non-skid coating described herein attempts to overcome the deficiencies of the conventional coatings with improved external durability and color retention, a reduced level of VOCs, and direct-to-metal (DTM) adhesion using organo-siloxane chemistry. The non-skid coating has a first component having an amino-functional siloxane resin; a second component having a non-aromatic epoxy resin; a spherical filler for lowering viscosity; a pigment; a coarse aggregate; and a thixotropic agent. The amino-functional siloxane resin can be an amino-functional methyl phenyl polysiloxane, diphenyl polysiloxane or silsesquioxane-based resin. The non-aromatic epoxy resin can be cycloaliphatic or aliphatic. The first component is about 5% to 20% weight of the coating, and the second component is about 80% to 95% weight of the coating.

Direct-to-metal and exterior durable non-skid coating

Direct to-metal and exterior durable non-skid coating

Disclosed are methods for applying and curing a multilayer coating on a substrate. The methods include applying to an aluminum substrate a primer composition, coalescing the composition to form a substantially continuous film over the substrate, exposing the film to radiation to cure the film, applying a second composition to the cured film, coalescing the second composition to form a substantially continuous second film, and curing the second film. The primer composition includes a polyene and a polythiol.
