Abstract
Abstract A fluid adhesive composed of phenol formaldehyde resin and sufficient di(alkyl Carbitol) formal, where the alkyl radical contains from 1 to about 12 carbon atoms and yields a fluid composition, this fluid composition permits an elastomeric hose having an innertube of nylon to be adhered to a sulfur curable elastomer. This is reinforced by textile braid and covered with suitable Neoprene cover. This hose is suitable as a pressure hose in refrigeration or automotive uses.
