2 A water-based, VOC compliant COATING , DACROMET is com-prised mainly of overlapping zinc and aluminum flake in an inorganic Way corrosion protection Barrier protection : Overlapping zinc and aluminum flakes pro-vide an excellent barrier between the steel substrate and thecorrosive media Galvanic Action: Zinc corrodes to protect steel Passivation: Metal oxides slow down the corrosion reaction ofzinc and steel to provide 3 times greater corrosion protection thanpure zinc Self-Repairing: Zinc oxides and carbonates migrate to thedamaged area of the COATING to actively repair the COATING andrestore barrier protectionEnvironmental Benefits Chromium-Free Alternative- GEOMET is the replacement for DACROMET inorder to comply with the following regu-lations.

4 Conductive- Concentration of metallicflake allows an electrical current to bepassed to the substrateThe DACROMET product line shows versatility in application and performance, with COATING systemsdeveloped to meet functional criteria that are specified by worldwide OEM s and suppliers. The followingare the formulations that have been engineered with your needs in mind: DACROMET 320 - Contains low Volatile Organic Compounds (VOC s) below Federal andState regulations DACROMET 320 LC- Formulated as a response to industry restrictions on chromium, this LVformulation contains Low Chromium and falls within current and near-term anticipated regulations DACROMET 500 - Almost identical to standard DACROMET 320 , this LV formulation usesPTFE in the basecoat to offer consistent torque-tension characteristics without a supplemental sealer(Available in LC)

5 DACROMET 320 HS- In order to achieve thicker COATING weight in an efficient manner, this LVformulation was engineered for various Dip-Drain parts such as fuel filler tubes, stampings, ApplicationDACROMET is applied using conventional Dip-Spin, Spray or Dip-Drain-Spin equipment following analkaline and/or mechanical cleaning cycle. COATING thickness can be varied by altering elements in theapplication processes. DACROMET is cured at 610 F PMT (peak Metal temperature), which must bemaintained for 15 SealersThe PLUS sealers, developed to complement the DACROMET COATING , provide a complete coatingsystem that sets industry standards with dynamic versatility.

6 The PLUS sealers, applied in one coatover DACROMET , provide the following characteristics:SteelPLUS SealerDACROMET Consistent torque/tension values Extended corrosion protection Extended bimetallic protection Extended resistance to solvents, gasoline and brake fluid Available in a variety of colorsTorque/Tension PropertiesThe PLUS sealers provide consistent torque/tension that compares with Cadmium andCadmium + CuringDip-Spin Monobake- Following the application of the first coat, the partsare baked to a Metal temperature of 3500-4500F for 15 minutes, whichsets the COATING .

7 The second coat is then applied and baked at 6100 FPMT for 15 minutes to provide the final cure of both Following the application of the COATING viaspray, the parts are exposed to induction heating that quickly elevates thetemperature to 6100F. This process is quick, efficient and compact be-cause the parts are cured in a matter of ResistanceSalt Spray - The DACROMET COATING systems provide Salt Spray protection (per ASTM B-117 /ISO 9227) in excess of 500 hours on threaded fasteners. With the addition of the PLUS sealers, protection exceeds 1000 following pictures show a comparison of standard Zinc Plating and DACROMET 320 320 L1000 Hours Salt SprayZinc PlatingCyclic Tests- In order to establish a correlation between accelerated corrosion tests and real-life performance, automotive manufacturers have developed their own test methods.
