Polyol compositions comprising a polyol, an insoluble fluorinated compound and a surfactant composition which is the reaction product of a stoichiometric excess of a polyisocyanate and a polyalkylene glycol monoalkyl ether of formula R--A--OH, wherein R is C.sub.1-25 alkyl and A is a polypropylenoxy chain, optionally containing up to 25% polyethylenoxy units, having a total length of from 4 to 39 units.

Polyol compositions

Process for preparing lignocellulosic bodies by bringing lignocellulosic parts into contact with a composition comprising a polyisocyanate, fumed silica and a non-ionic liquid gellant and by pressing this combinations of parts and composition. The adhesion of the parts is excellent and the binder composition can be easily sprayed.

A fire retardant composition comprising a dispersion of a solid fire retardant additive in a liquid isocyanate-reactive compound having a functionality of from 2 to 8 and an average equivalent weight of from about 31 to about 5000 and, as anti-settling agent, an effective amount of a fatty acid ester and/or amide. The composition is useful for preparing polyurethane foams.

Polyisocyanate composition comprising an organo clay and a cyclic alkylene carbonate. The composition is useful for wood-binding, preparing polyurethanes and rigid and flexible polyurethane foams.

Polyisocyanate composition

Novel compositions comprising isocyanate-reactive hydrogen containing compounds, an organo clay and a cyclic alkylene carbonate. The compositions are useful for making flexible polyurethane foams and rigid polyurethane and polyisocyanurate foams.
