A method of providing fire protection to a structure includes the step of installing an intumescent mesh on a surface of the structure such that the intumescent mesh is exposed to outdoor environmental conditions. The intumescent mesh includes a mesh with a series of openings and an intumescent coating applied to the flexible grid such that air can pass through the openings in the intumescent mesh. The intumescent coating includes expandable graphite and a polymer-based carrier; and the intumescent coating does not degrade when exposed the outdoor environmental conditions. The intumescent coating remains flexible and resists cracking and spalling from the flexible grid.

The invention relates to flame-retardant foam coatings for textile sheet products, wherein the coatings include plate-like expandable graphite which has a reduced salt content and a particle distribution with a proportion of >80 percent by weight having a diameter of at least 0.2 mm, and/or a minimum proportion of 70% having a mesh size of >50 mesh (0.3 mm), at least one binder and at least one foam stabilizer, and also processes for the production thereof, the use thereof for producing textile sheet products and also textile sheet products having such flame-retardant foam coatings.

Solventborne binder compositions which include a copolymer obtained by reacting a mixture of monomers in the presence of an organic solvent, wherein the monomer mixture includes an ethylenically unsaturated monomer and a vinyl ester monomer having a formula CH.sub.2CHXC(O)R, where R is a linear or branched alkyl group having 2 to 18 carbon atoms, an aromatic group having 6 to 12 carbon atoms, or R is bonded to X to form a 5- to 7-member ring, and X is O. Intumescent coatings containing the solventborne binder compositions, and substrates coated with the intumescent coatings are also disclosed.

A combination seal connects a filter or an equipment component to a base. The combination seal includes a seal material and flecks or particles made of intumescent material interspersed within the seal material. The flecks or particles of intumescent material undergo a chemical change when exposed to flames or heat and expand to maintain seal effectiveness and longevity without compromise.

The invention relates to a halogen-free, intumescent fire-proof coating, characterized in that it contains at least one terpene- and/or polyterpene-based film-forming binder, and to the use thereof.

The subject matter of the present invention comprises a non-toxic, eco-friendly fireproof composition made substantially of all naturally occurring materials. The instant fireproof composition is inclusive of any vegetal biomass and is specifically applicable in the manufacturing of a non-toxic, fireproof wood, non-toxic, fireproof textile fabrics, and intumescent fireproof coating composition, for fire protection applicable to both residential and industrial construction, as well as numerous consumer related products, materials, and devices. The extensive use of the instant fireproof composition provides a solution to the public health concerns accompanying the use of present-day, extremely dangerous, cancer-causing fire retardants.

The present disclosure relates to a multilayer composite or multilayer laminate that may include a core foam layer, and a first ceramifiable barrier component contacting the core foam layer. The ceramifiable barrier component may include a ceramifiable layer. The multilayer composite may have a HBF flammability rating as measured according to ASTM D4986.

A reactive resin system for intumescent coating can be made. Intumescent coatings are used for fire protection of metallic building components. In the event of a fire, said coatings undergo reactive foaming that results in the formation on the metal girder of a fireproof insulating layer having low thermal conductivity and that retards any early, thermally induced failure of said building component. A methacrylate-based resin system is produced by a process in which a first monomer fraction is polymerized to a maximum degree of 95% by weight and diluted with a second monomer mixture. The glass transition temperature of the polymeric component of the composition that is formed is low compared with the art. Organic acids incorporated into the resin system have synergistic effect with the filler system. The resin systems produced are found to be efficient at thermally induced foaming, because of their fine-pored and closed-pored foam structure.

A coating composition includes a first composition comprising a polymeric binder comprising a hyperbranched polymer or a polymer comprising a covalently bonded surfactant; a second composition comprising a coagulating agent; and an additive comprising an intumescent agent, a vibration damping agent, an insulation agent, or a combination of two or more thereof; wherein: the additive is present in the first composition, the second composition, or both the first and second compositions; the intumescent agent comprises an acid source, a carbon source, and a gas forming agent; the vibration damping agent comprises a first filler; the insulation agent comprises a second filler; and the first composition and the second composition are configured to form a coating within 30 seconds of application to a substrate, and the coating is non-sagging, water-resistant, and dry-to-the touch.

An article contains a polymeric foam board having a primary surface and an intumescent coating on a primary surface of the polymeric foam board, the intumescent coating containing a polymeric binder, expandable graphite particles, a phosphorous material and a boron-containing compound and wherein the article is free of an object that is in contact with the intumescent coating and that sandwiches the intumescent coating between it and the polymeric foam board and wherein the intumescent coating has a tensile elongation of at least 50 percent and less than 100 percent at 23 degrees Celsius as measured according to ISO 37, has a storage modulus of less than 110.sup.6 Pascals at 250 degrees Celsius, is halogen-free, free of sodium silicate, free of polyurea elastomer, and free of formals of pentaerythritol and dipentaerythritol.
