The invention relates to an aqueous dispersion containing a mixture of linear fluorinated and non-fluorinated polyurethane acrylates, obtainable by: a) reacting polyisocyanate A′, multi-unsaturated OH-functional compound B′, acid-functional polyol C′ under urethane formation reaction conditions in the presence of intermediate X, wherein intermediate X is an OH-functional (per)fluoropolyether (PFPE) derivative, and b) adding neutralizer D to the reaction product of step a) and dispersing it in water. The dispersion can be used in preparation of a coating with easy-clean, anti-stain and anti-scratch properties, which can advantageously be used for coating substrates in consumer electronics or automotive applications.

Specifically, the present invention provides a decorative sheet comprising a laminate, the laminate comprising at least a base material sheet and a first surface-protecting layer in sequence in the thickness direction; (1) the first surface-protecting layer comprising an ionizing radiation-curable resin containing two kinds of aliphatic urethane acrylates, i.e., resin A and resin B, wherein resin A is an aliphatic urethane acrylate with an isocyanurate skeleton, and resin B is an aliphatic urethane acrylate with an alicyclic skeleton without an isocyanurate skeleton, (2) the first surface-protecting layer having a nanoindentation hardness of 160 MPa or more and 240 MPa or less, and (3) the base material sheet comprising a polyolefin resin and having a nanoindentation hardness of 30 MPa or more and 80 MPa or less.

A restorable anti-glare film is disclosed. The restorable anti-glare film comprises a transparent substrate and a restorable anti-glare layer comprising a siloxane-containing urethane (meth)acrylate copolymer and a plurality of (meth)acrylic resin particles formed on the transparent substrate, wherein the weight average molecular weight (Mw) of the siloxane-containing urethane (meth)acrylate copolymer is between 4,000 and 60,000, and the (meth)acrylic resin particles have a 30% compressive strength of 14.7 MPa to 49 MPa and a recovery rate of more than 22%. The present restorable anti-glare film can provide a scratch-restorability and a stable and reliable anti-glare property.

Disclosed is a surface covering including: a wood-based substrate; a surface coating layer, the surface coating layer being obtained by the irradiation of a radiation-curable coating agent with UV light having a wavelength included from 120 nm to 230 nm; and a filler coating layer, the filler coating layer being located between the wood-based substrate and the surface coating layer. Also disclosed is a method for the manufacture of such a surface covering.

Disclosed is a dual UV and reaction curable, two component adhesive comprising both acrylic chemistry and polyurethane chemistry. The UV curable acrylate component provides a fast cure reaction to generate a tack-free surface. The mixed two component polyurethane cures to a reaction product that provides flexibility and chemical resistance. The adhesive is useful as fold protection for spiral filtration modules. When cured on a membrane the adhesive will maintain integrity and adhesion to membrane after treatments of creasing and soaking at high temperature, pressure, and wide pH ranges.
