A method is useful for producing a urethane(meth)acrylate resin composition. The method improves storage stability and reduces the reactivity drift of the composition compared to compositions made by other means from the same starting materials. In particular, it reduces the degradation of TEMPOL in mixtures with branched urethane resins.

In an aspect, tunable macroporous materials as described herein can be used to determine the presence of a certain type(s) and quantity of liquid in a liquid mixture.

Systems and methods provide a polyurethane foam. One method may obtainable the polyurethane foam by mechanical foaming with a starting mixture comprising a polyurethane dispersion, the polyurethane being composed of at least one polyisocyanate component and at least one polyol component, and at least one surfactant. The polyol component or at least one of the polyol components may comprise at least one comonomer having flame retardancy effect and containing two hydroxyl groups. The adhesive tapes produced therefrom may adhesively bond components in vehicles, aircraft or trains, or in electronic devices.

Providing a laminate having an excellent adhesiveness between a base layer and a surface layer while having a good flexibility. In order to solve the aforementioned problems, the laminate of the present disclosure comprises at least a base layer, an intermediate layer and a surface layer, wherein a base layer composition contains an urethane resin, an intermediate layer composition contains an energy ray curable resin having (meth)acryloyl group in a molecule thereof, and, a non-UV curable resin having only isocyanate group as reactive functional group, and a surface layer composition contains a UV curable resin having the (meth)acryloyl group in the molecule.

A display film includes a transparent polymeric substrate layer and a transparent energy dissipation layer disposed on the transparent polymeric substrate layer. The transparent energy dissipation layer includes cross-linked polyurethane and a polyacrylate polymer. The transparent energy dissipation layer has a glass transition temperature of 27 degrees Celsius or less and a Tan Delta peak value of 0.5 or greater.

A two-component polyurethane composition made of a polyol component and a polyisocyanate component, wherein the polyol component includes at least one reaction product of castor oil with ketone resins A1, at least one aliphatic triol A2, an aliphatic diol A3, and a polybutadiene polyol A4. The polyurethane composition has high strength and only a minor dependence of mechanical properties, especially of strength, on temperature, especially in the range from 60 C. to +60 C. Moreover, the composition is capable of curing without blistering under ambient conditions, even in the presence of substrates that typically promote foaming reactions owing to the presence of residual moisture, for example glass fiber weave.

A resin formulation that can be cured thermally or by light, where the cured resin is an amorphous, thermoset polymer.

A method of forming a three-dimensional object is described. The method may use a polymerizable liquid, or resin, useful for the production by additive manufacturing of a three-dimensional object, comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from said first component.

A method of forming a three-dimensional object is carried out by: (a) providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; (b) filling the build region with a polymerizable liquid, the polymerizable liquid including a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from the first component; (c) irradiating the build region with light through the optically transparent member to form a solid polymer scaffold from the first component and also advancing the carrier away from the build surface to form a three-dimensional intermediate having the same shape as, or a shape to be imparted to, the three-dimensional object, and containing the second solidifiable component carried in the scaffold in unsolidified and/or uncured form; and (d) concurrently with or subsequent to the irradiating step, solidifying and/or curing the second solidifiable component in the three-dimensional intermediate to form the three-dimensional object.
