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 1×10.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.

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.

Disclosed is a flame retardant coating for a textile sheet product, which contains at least one binder or a binder mixture, expandable graphite particles and additionally at least one chemical flame retardant. The grain size of at least 80%, preferably 100%, of the expandable graphite particles is at most 100 μm.

Disclosed are an intumescent fire-retardant coating with ultra-high corrosion resistance and a preparation method thereof. The fire-retardant coating is composed by water, wetting and dispersing agent, defoaming agent, composite carbon-forming catalyst, composite blowing agent, pentaerythritol, titanium dioxide, Mg(OH).sub.2, mica powder, kaolin, anti-rust pigment, aluminum tripolyphosphate, VAE emulsion, freeze-thaw agent, film-forming aid, and thickener. On the basis of the existing fire-retardant coatings, the present disclosure adds a series of anti-corrosion, heat insulation fillers and salt spray resistance additives to achieve a certain salt spray resistance effect. The fire-retardant coating of the present disclosure has both fire-retardant and anticorrosive functions, does not contain organic solvents, is low in price, has high construction tolerance, and has broad application prospects in the field of intumescent fire-retardant coatings.

Described herein is a corrugated intumescent composite structure comprising at least one metal mesh layer secured on or in an intumescent material, wherein the composite structure comprises a plurality of alternating flanges and ribs. In one embodiment, the corrugated intumescent composite structure disposed onto a metal decking for fire protection.

The present invention discloses an intumescent coating composition, a method for coating a substrate with said composition, a substrate coated with said composition, an article comprising said substrate, and a method to provide fire protection for a battery and/or an article comprising a battery in particular a vehicle comprising a lithium ion battery.

A composition that forms an insulating layer contains an epoxy-thiol-based binder. Because the expansion rate of the composition is relatively high, coatings having the layer thickness required for the relevant fire resistance duration can be applied in a simple and rapid manner, and it is possible to reduce the layer thickness to a minimum while still achieving a good insulating effect. The composition is particularly suitable for fire-protection, in particular as a coating for metal and non-metal substrates, e.g., steel components such as supports, beams, and truss members, to increase the fire resistance duration thereof.

The invention relates to diorganylphosphinic salts containing 0.0001% to 99.9999% by weight of iron, to a process for preparation thereof and to the use thereof.

The invention relates to a mixture containing as component A at least one organic phosphinic acid salt and as component B at least one alkali metal stannate (M′.sub.2SnO.sub.3), alkali metal hydroxyl stannate (M′.sub.2Sn(OH).sub.6), alkaline earth metal stannate (M″SnO.sub.3) and/or alkaline earth metal hydroxy stannate (M″Sn(OH).sub.6). The invention relates also to the use of such a mixture.

An intumescent coating composition comprising: (i) at least one epoxy binder; (ii) at least one support free silane; and (iii) at least one curing agent.
