Tectyl 603

Tectyl 603, is a polymeric, water-emulsifiable, corrosion-preventive film specially formulated for coating phosphated and painted parts such as hinges, bolts, screws, brackets, fasteners, etc. It contains a special additive system which provides a durable, self-healing, corrosion resistant film. The concentrated coating is an amber liquid while the cured film is clear and transparent. 

Easy Application: This product is applied as a water emulsion. It is normally applied in a dipping operation. 

Long-Term Protection: This product deposits a self-healing film on phosphated parts and components that provides salt spray protection superior to conventional water soluble rust preventive oils. Phosphated parts coated with an emulsion of 20 percent Tectyl 603 and 80 percent water will pass the 240 hour salt spray test requirement of the General Motors 6035-M phosphating specification. 

Maximum protection and performance can only be obtained when applied to properly phosphated components. This product will not compensate for inadequate phosphating. Adequate phosphating per the General Motors 6035-M specification is 2,000 - 3,000 milligrams of zinc phosphate per square foot of coating area. 


  1. Charge tank with de-ionized water 
  2. Begin mixing and bring water temperature to 140 - 160F (60 - 71C). 
  3. Add Tectyl 603 slowly, with agitation, to develop a 20 percent emulsion. NOTE: When mixing, always add this product to the water, never in reverse order. 
  4. The emulsion temperature at the time of initial fill and application should be 140 - 160F (60 - 71C). 
  5. Mechanical agitation (not air) is required at all times. 

Caution: Refer to Daubert's Safety Data Sheet for health and safety information. 

NOTE: The addition of any product over or under this coating is not recommended. The use of additional coatings could result in chemical incompatibility, thus adversely affecting the performance of this coating as stated in the lab data section. If a product other than Daubert Chemical Company's recommended product is required, written authorization must be obtained from Daubert Chemical Company.
