Disclosed herein are improved waterproof seam tapes and methods of producing the same.

The description relates to solvent free films and textiles that receive the solvent free films.

There is provided retroreflective articles comprising a binder layer comprising an adhesive composition comprising at least one tackifier and at least one elastomer selected from at least one of natural rubbers and synthetic rubbers, and a layer of optical elements at least partially embedded in a major surface of the binder layer. There are also provided articles of clothing using the presently disclosed retroreflective articles and methods for preparing the retroreflective articles.

The invention relates to a polymer thick film (PTF) conductive paste composition comprising a conductive powder, a fluoroelastomer, a silane coupling agent, and one or solvents. The PTF conductive paste composition can be used to form a printed conductor and to form an electrically conductive adhesive on various articles. The PTF conductive paste composition is provides a stretchable electrical conductor for wearables.

The present invention relates to a dimensionally stable adhesive compound which is formulated so as to be largely water- and solvent-free and can be brought into contact with the substrate to be bonded by being wiped on in the form of a thin adhesive film that is suitable in particular for bonding materials obtained from plant fibers. The organic constituent of the adhesive compound according to the invention consists predominantly of a mixture of polyether polyurethanes which are end-capped with at least two monohydric aliphatic alcohols of different chain lengths. The invention also relates to a method for applying a tacky film to a planar substrate, preferably to paper, by wiping the adhesive compound onto the point of contact with the substrate.

Provided is an anti-chafing thigh guard. The anti-chafing thigh guard includes at least one adhesive patch. Each adhesive patch in the at least one adhesive patch is constructed of a linear sheet of material having a top surface and a bottom surface. The top surface defines a non-abrasive texture. The linear sheet of material comprises an elastic, flexible, water-resistant, and hypoallergenic material. The sides of the at least one adhesive patch are defined by a geometrical shape of a first linear side connecting two rounded ends which are thereby connected by a curved second side, wherein the curvature of the second side allows the at least one patch to adhere to variable polar curvature of a user's skin. The geometrical shape of each patch provides a surface area configured to provide full coverage of an area of a user's skin subject to increased friction.

A pressure sensitive adhesive composition comprising a product made from: (i) an acetoacetic ester; (ii) a diacrylate; (iii) a crosslinking agent that contains more than two acryloyl groups; and (iv) a catalyst.

The present invention is related to a high frequency easy melting multiple layered structure, which includes a high frequency easy melting coating layer; a high frequency easy melting adhesive layer installed below the high frequency easy melting coating layer and a high frequency easy melting thermoplastic polyurethane (TPU) substrate placed below the high frequency easy melting adhesive layer. They serve to reduce the energy and time period in the high frequency melting and connection so as to promote producing speed and capacity effectively.

A method of preparing thermoplastic polyester elastomer membrane with high binding strength includes the following steps: (a) Adding a reaction solvent to TPEE powder or granules to prepare a solvent mixture, (b) Adding a modifier to the solvent mixture, and mixing uniformly to prepare a first mixture, the modifier including at least one of o-xylylenediamine, m-xylylenediamine, alpha,alpha′-diamino-p-xylene, 2,3,5,6-Tetrachloro-p-xylene-alpha,alpha′-diamine, and 1,3,5,7-Tetraazatricyclodecane. (c) Adding an initiator to the first mixture, and mixing uniformly to prepare a second mixture, (d) Obtaining a finished product by passing the second mixture through an injection laminating process.

A moisture-curable hot-melt adhesive composition is disclosed. This moisture-curable hot-melt adhesive composition contains: a urethane prepolymer including a polymer chain, which includes a structural unit derived from a polyol and a structural unit derived from a polyisocyanate, and having two or more isocyanate groups; and a modified urethane prepolymer including a polymer chain, which includes a structural unit derived from a polyol and a structural unit derived from a polyisocyanate, and having one or more isocyanate groups modified with a castor oil monool.
