The present invention provides methods and articles for achieving puncture-resistant waterproofing membranes and for waterproofing building and civil engineering surfaces without requiring the use of separate protection boards. Exemplary membranes and methods of the invention rely on relatively thin, flexible composite layers to provide impact resistance while yet facilitating seaming between adjacent installed membranes and minimizing formation of wrinkles, leakage channels, and “fish mouth” openings, particularly at substrate details or other surface irregularities.

A pre-laid polymer waterproof rolling material, which comprises a sheet-like polymer carrier, a hot-melt pressure-sensitive adhesive layer on the sheet-like polymer carrier, and an anti-sticking coating on the hot-melt pressure-sensitive adhesive layer; The anti-sticking coating comprises the following components: 100-160 parts by weight of water; 50-80 parts by weight of a polyurethane resin; 15-20 parts by weight of a pigment; 10-12 parts by weight of a filler; 0.3-1 part by weight of a cross-linking agent; 0.5-1 part by weight of an antioxidant; 1-2.5 parts by weight of an anti-ultraviolet agent; and 0.03-0.2 part by weight of a thickener. The anti-sticking coating in the present application uses water as a solvent, water is non-toxic and non-corrosive, thus there is no environmental pollution problem in the production process.

A pre-laid polymer waterproof rolling material, which comprises a sheet-like polymer carrier, a hot-melt pressure-sensitive adhesive layer on the sheet-like polymer carrier, and a plurality of anti-sticking particles on the hot-melt pressure-sensitive adhesive layer, wherein the particle size of the anti-sticking particles is smaller than the thickness of the hot-melt pressure-sensitive adhesive layer; the surface of the anti-sticking particles is coated with an organic layer; and the anti-sticking particles are connected with the hot-melt pressure-sensitive adhesive layer by means of the organic layer; the organic layer comprises the following components: a solvent, a polyurethane resin, a pigment, a filler, a cross-linking agent, an antioxidant, an anti-ultraviolet agent and a thickener. The anti-sticking particles will not shed during transportation and will not be trapped into the hot-melt pressure-sensitive adhesive layer, such that the hot-melt pressure-sensitive adhesive layer is exposed to the outside.

According to one embodiment, a process for applying an adhesive material onto a barrier sheet substrate is provided. The process includes providing an adhesive material having viscosity of at least about 10,000 centipoise at 250° F. The adhesive material is applied to a multitude of cavities on a surface of a first tool with a coater unit in close proximity to the surface. The adhesive material is transferred from the surface of the first tool to the substrate supported on a surface of a second tool and pressed against the surface of the first tool.

A thermally expandable fire-resistant material composition comprising an adhesive base and an a thermally expandable compound, wherein the thermally expandable fire-resistant material composition is flowable at an ordinary temperature or at a temperature lower than the expansion onset temperature of the thermally expandable fire-resistant material, and is solidifiable or curable.

The present invention relates to the construction of an adhesive film which is self-adhesive on one side and has a bond-friendly surface, to a method for producing a one-sidedly self-adhesive film of this kind, to a method for applying the one-sidedly self-adhesive film, more particularly for full-area application to a substrate, e.g., a floor, a wall or a ceiling, and also to the use of the self-adhesive film for application, more particularly full-area application, to a substrate, and for applying an adhesive and/or a leveling compound on the bond-friendly surface of the self-adhesive film.

To provide an aqueous adhesive for an inorganic material with excellent adhesiveness to the inorganic material. An adhesive improver (J) for an aqueous adhesive for an inorganic material including a copolymer (A) containing an unsaturated (poly) carboxylic acid (anhydride) (a1) and a (meth) acrylic acid alkyl (2 to 30 alkyl carbon atoms) ester (a2) as a constituent monomer; and an aqueous adhesive for an inorganic material (X) including the adhesive improver (J), saccharide (B), a polycarboxylic acid (C) having 4 to 24 carbon atoms and water.

A heat and/or UV/LED activated single or double-sided tape is configured to seal multiple sheets of single or multilayer composite film with the film including an outer fluoropolymer layer. A repair kit includes a single-sided and/or double-sided heat and UV/LED activated adhesive tape, portable surface treater, and portable heat/UV/LED generating device. The single-sided and/or double-sided heat and UV/LED activated adhesive tape is useful in the manufacturing of architectural applications and in repair of architectural applications.

The present disclosure relates generally to building surface joint supports, for example, suitable for covering a seam between two building surface panels, such as drywall. The present disclosure relates more particularly to a joint support including an encapsulated adhesive for securing the joint support to the building surface panels. The joint support includes a support strip having a width, a length, a first end, a second end, a contact surface, and an outer surface. An adhesive is disposed on the contact surface of the support strip. The adhesive includes a first set of capsules and each capsule of the first set of capsules includes a membrane enclosing a first component of an adhesive composition.

The present invention relates to an adhesive tape comprising a base material layer made of a flat yarn cloth, a first film layer made of a thermoplastic resin film layered on one surface of the base material layer, a second film layer made of a thermoplastic resin film layered on the other surface of the base material layer, and an adhesive layer layered on the surface of the second film layer opposite to the base material layer, in which the first film layer and the second film layer both contains a pigment.
