                              Doverphos S-9228’s high molecular weight, low volatility and high
                              phosphorous content provide superior thermal stability, giving you
                              outstanding processing protection against discoloration and thermal
                              degradation. Extremely good hydrolytic stability prevents the
                              formation of black specks and keeps blends uniform.

                              Dovernox D-Blends are available in a variety of compositions
                              containing antioxidants, phosphites and processing aids. Our exclusive
                              blends employ Doverphos S-9228, and we also offer many blends
                              comprised of standard industry formulations. Powder is the standard
                              physical form, but blends can be special ordered as granular products.

                              Dovernox D-Blend ratios and applications are listed in our product
                              brochure. If you don’t see what you need, we can develop
                              proprietary blends to meet your requirements.

                              Dover also offers specially blended Add *Packs based on calcium
                              stearate and waxes for PVC applications.

    PLAQUE A                    PLAQUE B
  Doverphos® S-9228 prevents yellowing and
  loss in physical properties during long term
  heat aging. This is shown in Plaque A which
  contains a competitive phosphite, versus
  Plaque B which contains Doverphos® S-9228.

                                   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 ®
HORDARESIN       CHLOREZ
 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
 applications.

 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.

DOVERGUARD
 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
 coatings.
