Disclosed are one-component compositions that include: (1) an isocyanate-functional urethane acrylate and (2) a polyisocyanate containing allophanate and/or uretdione groups, wherein the one-component composition has a viscosity of less than or equal to about 800 mPa&#xb7;s and an isocyanate content of greater than about 5% by weight, based on the weight of the one-component composition. Also disclosed are circuit boards and electronic components that are coated with such compositions.

One-component, dual-cure conformal coating compositions

Composition and process for low temperature curing of polyuretdione-polyol compositions in which the polyuretdione is prepared from a polyisocyanate with isocyanate groups and a polyol containing primary hydroxyl groups. The catalyst for the composition and process is an amine catalyst containing the group &#x2014;N&#x2550;C&#x2014;N&#x2014;, being aprotic, having a pKa greater than 20 and upon addition to the liquid coating composition causing a phase-change of the coating composition from liquid to solid at 25&#xb0; C. and 1 atm. within one week.

Low temperature curing polyuretdione compositions

The present invention relates to a non-aqueous coating composition comprising:

Non-aqueous polyurethane coating compositions

A polymeric material, prepared by reacting a mixture comprising a polyorganosiloxane having one or more isocyanate-reactive functional groups, polyisocyanate, and polyol, is provided. The isocyanate-reactive functional groups, typically one or two, are attached to only a single end of the polyorganosiloxane chains. The polymeric material may be used to form coatings on a substrate and to inhibit fouling on surfaces exposed to aqueous conditions.

Anchored polysiloxane-modified polyurethane coatings and uses thereof

Aqueous polyurethane coating compositions are disclosed in this specification. The aqueous polyurethane coating compositions contain a polycarbonate-polyurethane resin component, an aminoplast resin component, and a polyester polyol component.

Waterborne polyurethane coating compositions

Aqueous polyurethane coating compositions are disclosed in this specification. The aqueous polyurethane coating compositions contain a polycarbonate-polyurethane resin component, an aminoplast resin component, and a polyacrylic polyol component.

A polymeric material may be prepared by reacting a mixture comprising an amino functional polyorganosiloxane, polyisocyanate, and polyol. The polyol may comprise a hydroxy-functional poly(meth)acrylate. The polymeric material may be used as a coating for a substrate and may inhibit fouling on a surface exposed to aquatic conditions.

Thermoset siloxane-urethane fouling release coatings

Polysiloxanes terminated with one or more hydroxy functional carbamate groups are provided. The polymers may have the formula (I) wherein R, R, R, and Rare independently hydrogen, C-Calkyl, C-Cfluoro-substituted alkyl; cyclopentyl, cyclohexyl, benzyl, toluoyl, xylyl and/or phenyl; Rand Rare linking groups; Rand Rare independently hydrogen, C-Calkyl, cyclopentyl, cyclohexyl, benzyl, toluoyl, xylyl or phenyl; and Land Lare linking groups. Typically, x is such that the polymer has a molecular weight of about 1,000 to 100,000. Other polymeric materials produced by reacting with an isocyanate functional compound or a lactone and coating compositions containing such polymeric materials are also provided.
