                                   Dover offers two aqueous flame retardant systems:
                                        DOVERSPERSE A-1 is a dispersed solid and is used to flame retard coatings and textiles.
                                        DOVERSPERSE 3 is an emulsion based on a high viscosity liquid and is typically used to flame retard adhesive systems.

 Hordaresin and Chlorez are the brand names for Dover
 Chemical’s line of resinous chlorinated paraffins. These
 products are tasteless and odorless chlorinated paraffin
 resins especially soluble in aromatic and chlorinated
 solvents. They have limited or no solubility in lower
 alcohols, glycols, glycerines, and water. They provide
 low-cost flame retardancy for a wide variety of

 Hordaresin and Chlorez are compatible with most
 commonly used resins, rubbers, plasticizers, waxes, and
 drying oils. Because of their very high active halogen
 content and low cost, these products find wide usage
 as flame retardant additives in coatings, inks, plastics,
 foams, adhesives, paper and fabrics.

 Dover Chemical Corporation has developed a group
 of products based on the bromination and chlorination
 of a variety of olefins. Each has been developed to
 meet specific end-use needs. These products also can
 be compounded into a variety of polymer systems to
 provide efficient use of synergists.

 Both Doversperse A-1 and Doversperse 3 typically
 contain 45% available chlorine for maximum flame
 retardant efficiency. Because of their non-ionic base
 they find application in both cationic and anionic
 emulsion systems. In addition to their flame retardant
 contribution they improve adhesion, impact chemical
 and water resistance and allow the user to formulate
 aqueous systems rather than solvent systems.

 Doversperse A-1 is recommended if increased hardness
 is required. Use Doversperse 3 for plasticizing and
 tackifying. Application areas include adhesives, rubber
 coatings, inks, carpet backings, paper and fabric

          Dover PhosBooster products
          offer a whole new approach
          to processing flexible PVC
          compounds. Dover’s patent-
          pending complex phosphite
          ester mixtures improve both
          performance and cost. Used
                                                            DOVER PhosBoosters®
          as partial or full replacements of
          conventional mixed metal
          stabilizers, PhosBoosters
          reduce or eliminate heavy                                               Phosphite Ester
          metals and VOC’s.
          PhosBooster’s clarity, initial
          color, plate out reduction and
          long-term heat stability are
          shown above. These
          characteristics let you use less
          pigment, cut clean-out time
          and run hotter and faster.
