In a self-repairing polyurethane resin material produced by reaction of pentamethylenediisocyanate with an active hydrogen group-containing compound, the active hydrogen group-containing compound contains a polyol compound having a number average molecular weight of 100 to 2000 and an average functionality of 2 to 3.

A crosslinkable composition is useful for preparing a skin contact adhesive or a coating on a substrate. The crosslinkable composition includes (A) a polyurethane-polyorganosiloxane copolymer and (B) a curing catalyst. The skin contact adhesive prepared by crosslinking the crosslinkable composition is useful in applications such as adhesives for medical tapes, adhesives for wound dressings, adhesives for prosthetics, ostomy appliance adhesives, adhesives for medical monitoring appliances, adhesives for scar therapy treatments, adhesives for cosmetic patches, and transdermal drug delivery systems.

The present invention provides a polyaspartic composition comprising a reaction product of a polyamine and a Michael addition receptor reacted in the presence of a catalyst comprising a phenolic compound, with the proviso that the phenolic compound is not a phenol which is substituted with tert-butyl groups in both ortho positions to the oxygen. Suitable phenolic compounds include phenols, phenolic aldehydes, alkylphenols, benzenediols, cashew nut oil, and combinations thereof. Coatings, adhesives, sealants, composites, castings, and films comprising a polyurea composition may be made by reacting a polyisocyanate with the inventive polyaspartic composition. In particular, floor coatings made with the inventive polyaspartic composition have an elongated work time and a short walk-on time compared to current floor coatings.

An electrocoat system for electrodeposition is described. The system includes an inorganic bismuth-containing compound or a mixture of inorganic and organic bismuth-containing compounds. The system demonstrates a high degree of crosslinking and produces a cured coating with optimal crosslinking and corrosion resistance.

The invention relates to a hyperbranched polymer comprising:

a) a hyperbranched polycondensate with hydroxyl end groups, amino end groups, or a combination thereof condensed to
b) one or more linking groups connected to
c1) one or more polyethylene glycol monomethyl ethers and
c2) one or more poly(C.sub.2-C.sub.3)alkylene glycol mono-(C.sub.8-C.sub.22)-alkyl ethers,
wherein the weight ratio of components c1):c2) is from 9:1 to 1:9. It further relates to a process for producing the polymer, to a composition comprising the polymer and an active ingredient, and to a method for controlling phytopathogenic fungi or undesired vegetation or insect or acarid infestations or for regulating the growth of plants.

The present invention provides a blocked isocyanate composition comprising a blocked isocyanate compound in which an isocyanate group of an isocyanate compound is blocked with a fluoroalcohol compound, and at least one amidate compound represented by the following Formula (2):

##STR00001##

wherein B, G, J, R.sup.7. and R.sup.8 are as defined in the specification.

In a polyurethane gel 1 including a gel layer 2 and a coat layer 3 covering the gel layer 2, the gel layer 2 is produced by allowing at least aliphatic polyisocyanate having an average functionality of more than 2.0 to react with polyol having an average functionality of 3.0 or less, and the coat layer 3 is produced by allowing at least aliphatic diisocyanate and/or alicyclic diisocyanate to react with bifunctional active hydrogen compound.

A method for deblocking a blocked isocyanate is described herein. The method includes contacting a blocked isocyanate and a halide ion source under conditions effective to provide a deblocked isocyanate. A method of making a polyurethane is also disclosed. The method of making a polyurethane includes combining a blocked isocyanate, a polyol, and a halide ion source in the presence of solvent and under conditions effective to provide the polyurethane.
