Abstract: Chlorinated polyethylene mastic adhesive compositions, and process for the production of such compositions, formed from chlorinated polyethylene and a compatible plasticizer. These mastic compositions are useful for bonding and sealing together membranes, particularly chlorinated polyethylene membranes, at ambient conditions without application of heat. The ability to form seals of high peel strength in roofing applications without the use of heat is of particular importance. In another embodiment however, cross linking agents can be incorporated within the recipe, and seals of even greater peel strength obtained. Heat is required in the sealing operation in this instance to produce cross linking of the polymer. One thus has the choice of forming adhesives of high peel strength for roofing applications without any necessity of using heat; or, alternatively, to form adhesives of even greater peel strength with the use of heat.
