Abstract

Urea-formaldehyde resin foams for airtight seals are prepd. from a two part water based system contg. (all wt.%) 30-70 of (A) urea-formaldehyde precondensate, 0-10 foam producing surfactants, 0-20 resin modifying agents and 1-15 of (B) acid catalyst as naphthalene-sulphonic acid-formaldehyde-condensate and/or dibutyl naphthalene-sulphonic acid, 0-10 surfactants, 0-20 resin modifying agent. At least either (A) or (B) should contain resin modifier and surfactant. Resin modifier at 0.01-20 concn. should consist of at least one glycol-ether of HO-(CH2-CH2-O)m-R, R is 1-4C alkyl gp. m is 1-3.
