The present invention provides fire-retarded rigid polyurethane foam comprising the reaction product of polyol and isocyanate foam forming components and a dialkyl phosphorus-containing compound, namely a reactive mono-hydroxyl-functional dialkyl phosphinates, as flame retardant, serving as highly efficient reactive flame retardant in said rigid polyurethane foam.

Recovery times and/or airflow of flexible polyurethane foam is increased by including certain tackifiers in the foam formulation. The tackifiers are characterized in being incompatible with polyol or polyol mixture used to make the foam, having a viscosity of at least 5,000 centipoise at 25#C and having a glass transition temperature of at most 20#C. The tackifier is pre-blended with certain monols to form a lower-viscosity blend that is combined with one or more other polyols and a polyisocyanate to form a reaction mixture for producing a polyurethane foam.

A polyurethane coating composition including: a polyol compound as a main agent; a polyisocyanate compound as a curing agent; and a quaternary ammonium salt composed of a tertiary amine compound and a weak acid.

The invention pertains generally to a shelf-stable polyurethane HFO-blown two-component polyurethane foam composition which includes controlling the ratio of tin-containing catalyst(s) to potassium-containing catalyst(s).

A polyurethane adhesive composition, more specifically a two-component polyurethane adhesive, including (a) at least one isocyanate component, and (b) at least one polyol component, wherein the polyol component (b) includes (bi) at least one first polyol compound, (bii) at least one second polyol compound and (biii) at least one chain extender, and a process for making the above adhesive composition.

A resin composition including a resin having an alcoholic hydroxy group and/or a carboxy group as a crosslinkable group, which exhibits excellent crosslinking reactivity to a polycarbodiimide compound and a polyoxazoline compound even at a low reaction temperature where the resin does not cause discoloration or thermal decomposition; a resin material including the resin composition; and a resin crosslinked body that is a reaction product of the resin composition are provided. The resin composition includes at least one resin (A) containing at least an alcoholic hydroxy group and a carboxy group; at least one crosslinking agent (B) selected from a polycarbodiimide compound and a polyoxazoline compound; and a specific organometallic compound (C). The resin material including the resin composition and the resin crosslinked body are provided.

Disclosed are polyurethane adhesive compositions which include (a) one or more urethane prepolymers having isocyanate moieties; (b) a catalytic amount of one or more catalysts; (c) one or more fillers; (d) one or more silane adhesion promoters; and (e) one or more monofunctional polyalkylene glycols.

The invention pertains generally to a low-pressure (100-250 psi) process of seaming adjacent seams of artificial turf using a one-component or a two-component polyurethane adhesive using an apparatus which employs a payoff spool of base material in the front of the apparatus and an activation trigger adjacent the handle to begin the application of polyurethane spray foam adhesive by connectivity between the application trigger and the foam spray gun trigger.

The invention relates to a method for producing polyurethane soft foams, in particular open-cell polyurethane soft foams based on polyether carbonate polyol and toluylene diisocyanate, wherein the resulting polyurethane soft foams have similar properties to the already known polyurethane soft foams and they are simpler and more sustainable in terms of their production.
