A polyaspartate composition is provided which comprises a reaction product of a diamine and a diester reacted at a ratio of diamine equivalents to diester equivalents of from 1:0.95 to 1:0.50. The polyaspartate compositions of the invention may be combined with polyisocyanates to produce polyurea compositions, e.g., coatings, adhesives, sealants, composites, castings, and films, which exhibit a faster cure time along with faster development time for physical properties such as hardness and tensile strength.

Faster cure polyaspartic resins for faster physical property development in coatings

Methods of producing an elastomer are disclosed that include (I) applying an actinic radiation curable composition preferably selected from a urethane (meth)acrylate, an allophanate urethane (meth)acrylate or a lactone-containing (meth)acrylate to a substrate at a thickness of at least 0.25 mm (10 mils); (II) exposing the composition ultraviolet radiation to produce a cured film; and (III) removing the film from the substrate. Related compositions are also disclosed.

Methods for making elastomers, elastomer compositions and related elastomers

A process of directly coating a metal substrate and curing the coating using radiation sources such as UV radiation having a wavelength of 200 nm and above. Furthermore, compositions of the invention can be used as a tie-coat for coatings that do not bond well directly to various metal substrates.

Direct-to-metal radiation curable 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

A composition that includes isocyanate group containing compounds that include on average i) a NCO functionality less than or equal to 3.5; and ii) from 1.5 to 8 percent by weight, based on the isocyanate containing compound, of allophanate groups; and which is substantially free of uretdione groups. The composition can be used in two component elastomeric coating compositions that include a component A the above-described composition and a component B that includes a compound containing one or more functional groups that are reactive with isocyanate groups. The elastomeric coating compositions can be used to coat substrates.

Allophanate modified polyisocyanates

This invention relates to flexible cycloaliphatic diisocyanate trimers and a process for the preparation of these. These flexible products are allophanate-modified, partially trimerized cycloaliphatic diisocyanates and are characterized by a low T. More specifically, the Tof the resultant product ranges from about &#x2212;30&#xb0; C. to about 40&#xb0; C., after the excess monomer has been removed from the product.
