The invention provides a unique thermoset viscoelastomeric reaction product and a container combination comprised of the supportive base equipped with a thermoset viscoelastomer reaction product possessing unexpectedly superior adhesive and cohesive efficacy rendering it especially useful as an adhesive insert in a container combination. The thermoset insert bonds to any suitable supportive structure. The unique viscoelastomeric reaction product inserts adhesively immobilize items placed thereupon and adhesively or permanently bonds to most conventional containers. The tenacious cohesive and adhesive features of the insert allows for inverted stowage of stowed items. Due to the confining adhesive and cohesive attributes of the insert, structural supports of a flexible or solid base without a conventional confining structure provide a unique container combination for the stowed items. Containers equipped with the unique insert also surprisingly provide an aseptic environment especially useful for hygienic applications.

Polyester films with abrasion resistant coatings and methods for making the same are provided. The coated polyester films include a polyester film substrate having a coating on at least one side thereof, wherein the coating is derived from a coating composition that includes (i) a melamine crosslinker component and (ii) a polyurethane component derivable from at least one diisocyanate and at least one polymeric polyol.

The invention relates to a polyisocyanate mixture comprising a polyisocyanate component A) having aliphatically and/or cycloaliphatically bonded isocyanate groups and a polyisocyanate component B) having araliphatically and/or aromatically bonded isocyanate groups, characterized in that the polyisocyanate component A) comprises at least 0.85% by weight of sulfonate groups (calculated as SO.sub.3; molar weight=80 g/mol) in chemically bonded form and the proportion of the polyisocyanate component B) is 7 to 43% by weight of the total amount of the components A) and B). The invention further relates to the use thereof and also coating compositions comprising the polyisocyanate mixture and also the substrates coated with these coating compositions.

Disclosed are a polyurethane foam composition for sound-absorbing materials, a method for manufacturing a polyurethane foam and a polyurethane foam manufactured using the method. Particularly, disclosed are a composition containing a polyol mixture including a polyol and an additive, and isocyanate, and the manufacture of a low-density polyurethane foam for sound-absorbing materials, which is imparted with improved appearance formability, reduced smell and enhanced sound absorption performance by controlling the content of the composition and the conditions for foaming the composition.

The present invention provides an anti-pilling wool fabric with a coating having pilling resistance and resistance to fiber loss from fabric surface. The coating is formed by a coating formulation including at least two diisocyanates, at least two catalyst, a water dispersing agent, a buffer and water, which provides a polycarbodiimide crosslinker reactive to the relative less reactive groups on polypeptide of the wool fabric and promotes crosslinking between polypeptides of the wool fabric under relatively mild processing conditions so as to enhance mechanical strength of the wool fabric whilst no significant effect of the original finish merino wool fabric and/or garment and fiber loss from fabric surface are observed, compared to conventional treatment methods on wool fabric. A corresponding coating formulation and method of fabricating the anti-pilling wool fabric are also provided. The present invention is applicable to finished wool fabric which fibers are already with colorant(s), and/or dye(s), and/or reactive dye(s).

A binder has at least one isocyanate and at least one biopolymer mixed with water. The biopolymer may be a biopolymer nanoparticle or cooked and chemically modified starch. Optionally, the binder may also include urea. The biopolymer and water are mixed, and the isocyanate is added to the mixture. The binder may have a viscosity that is suitable for being sprayed on a substrate to make a composite material, for example a viscosity of 700 cP or less or 500 cP or less at 40 C. The substrate may be wood, another lignocellulosic material, or synthetic or natural fibers. In particular examples, the binder is used to make no added formaldehyde wood composites including particle board and fiberboard. Alternatively, the binder may have a higher viscosity and be used to make plywood.

The present invention relates to the use of hydrophilized polyisocyanates for the production of water-diluted coating compositions which have a polymeric polyol content of not more than 10%.
