Abstract

In apparatus in which a mixture of aqueous urea formaldehyde or carbamide formaldehyde is supplied under pressure to a foam gun, the mixture is constantly agitated to prevent separation of the water and thermoplastic by a manually, mechanically, pneumatically or electrically operated stirrer or by recirculating part of the mixture as by a by-pass from a pump supplying the foam gun.
