A catalyst system and process are provided for producing polyurethane foams using a carboxylic acid blowing agent, wherein an organic polyol and an organic polyisocyanate are contacted with a catalyst system comprising a dialkylcyclohexylamine and an N-substituted alkoxyalkyl piperazine.

Catalyst system for use in producing carboxylic acid blown polyurethane

Polyurethane foams with excellent physical properties are obtained by using a catalyst composition of a tertiary amine and 2-ethylhexanoic acid.

Catalyst for making polyurethanes

Disclosed is a synergistic catalytic combination of 1,2-dimethylimidazole with tris(3-dimethylaminopropyl)amine and a salt of 1,8-diazabicyclo(5,4,0)undecene-7. The combination catalyst is useful in polyurethane systems such as elastomers, microcellular, rigid, semirigid, and flexible foams, such as integral skin semiflexible foams used in the manufacture of steering wheels.

Catalyst blend containing 1,2-dimethylimidazole

Polyurethane foams with excellent physical properties can be obtained by using a partial salt between N,N-dimethylaminopropane-1,3-diamine (DMAPA) and a branched octanoic acid.

Polyurethane foams with excellent physical properties can be obtained by using a partial salt between N,N-dimethylaminopropane-1,3-diamine (DMAPA) and phenol.

The biocidal activity of N-(2-methyl-1-naphthyl)-maleimide is vastly improved by chelating it with an amine wherein each free hydrogen on each amino group has been replaced by the groups --(CH.sub.2).sub.n COOY wherein n represents 1 or 2 and each Y represents hydrogen, ammonium or an alkali metal cation.

Biocidal chelate

The addition of a combination of CH.sub.3 SO.sub.2 CHI.sub.2 and certain chelating agents to cutting fluid prevents bacterial and fungal growth. Concentrated aqueous co-dispersions thereof are particularly useful.

Biocidal additive for cutting fluids

Polyurethanes based on a resole-type polyol can be significantly improved in their friability when the urethane catalyst is a fully neutralized tertiary amine salt and butyl benzyl phthalate is used as the plasticizer. The polyol is prepared by reacting a phenol and formaldehyde under substantially anhydrous conditions with continuous removal of water, and has a water content of no more than about 5%.

Process for rigid foams of improved friability

Paint compositions containing an industrial biocide can be prevented from yellowing by the addition of a small amount of a certain mercury salt.

Paint compositions

4-Tolyl diiodomethyl sulfone has been found to protect leather from fungal attack if it is incorporated into the tanning mixture in suitable amounts.
