Abstract
The addition of a chlorinated alkyl phosphate oil to a natural latex emulsion has enabled the formulation of water-based contact cements with the ability to instantly bond porous substrates together. The adhesives offer the user of solvent based contact cements an alternative more practical than hot melts, two-part water-based, or slower setting one-part water-based adhesives in industries where the immediate assembly of porous substrates is necessary.
