REPLICATION PUTTY

Description of DMR-503

DMR-503 Replication Putty is a two-part silicone elastomer with the consistency of a workable paste in a one-to-one mix. It is mixed by kneading with the fingers and is non-hazardous. Once mixed, DMR-503 can be pressed onto the object to be replicated and will cure rapidly at room temperature into a firm elastomer with a Shore A Durometer of 50, and a dimensional accuracy of 99.95%.

DMR-503 is designed for applications where a non-liquid replication material is needed.

Advantages of the DMR-Series Flexible Replication Systems

  • Quick and easy to mix & use
  • A replication material for any application
  • Cures fast at room temperature
  • Leaves no film or residue
  • Safe to use
  • Accurate dimensional qualities (minimal cure shrinkage)
  • Indisputable physical evidence – a permanent record
  • Can be used with optical comparitors for dimensional measurements
  • Available in two, eight and ten pound kit sizes (total weight of hardener and base).

DMR-503 is a product from the DYNAMOLD range.

Use

For fast setting, dimensionally stable measurement of tooling, mold making dies, gears, prototype tooling, production parts, surface finish replications and a number of other applications. Excellent for measuring wear on moving parts, production pieces against specification tolerances, overall quality of machined or plated surfaces, in conjunction with use of optical comparators, and corrosion pitting.

Precautions

Handling: Vinyl gloves are recommended (do not use latex gloves as the curing process may be inhibited) to protect hands and fingernails from putty residue. Wear apron and footwear impervious to this material. Other substances that could possibly inhibit the cure of DMR-503 include chlorinated solvents, some adhesive tapes, some solvent carriers, most clay or clay based products, sulphur cure-organic rubber, amines-epoxy-TDI urethanes, some polyester gel coats and paints, condensation cure silicone RTV & urethane, composite pre preg, acetone, MEK, methyl chloride, some soaps and hand care products. There may be other substances that could cause difficulty, and not all of the above items will cause problems in every instance. Use with adequate ventilation. Storage: Do not store above 49°C/ 120°F. Keep containers tightly closed and upright. Store in a cool dry location away from direct sunlight, sources of intense heat, or where freezing is possible. Containment/ Clean Up: You will need to determine which federal, state and local laws and regulations are applicable. For more information regarding the danger of the product, please consult the product safety data sheet. It is advised to read this document prior to use. For industrial use only.

Directions for use

Mix in a ratio of 1 part side A to 1 part side B, by weight or volume measurement.Knead together until the material is a uniform colour, with no visible streaking.Release treat all surfaces with appropriate non-silicon release agent.Press into or on the object to be replicated, being careful not to entrap air. On some finely detailed parts, some manipulation of the putty may be required in order to obtain the best replica.Cure rate is 15-20 minutes. This may vary with ambient temperature or temperature of the surfaces that the material contacts.Shrinkage is 0.1% on cure. If latex comes into contact with DMR-503, there is a possibility that the cure could be inhibited. The use of gloves other than latex is recommended when mixing or handling.
