Silicone Mold Release Agents

MOLD RELEASE is an easy to use Silicone emulsion (i.e. milky white emulsion of Dimethyl Polysiloxane fluid). It is used as mold release agent and shining agent for tyre, rubber, and plastic industries. It is also used in High-speed offset printing process. In the plywood manufacturing industry, it prevents build up of glue and promotes easy removal of excess glue on platens and other parts of the presses used. In lamination and wood industry it is used as anti-tack material to the platens. It is used in glass industry for conveying equipments, treating molds, molded glass articles.


Special Features

  • Being an aqueous emulsion it is easy to handle & apply.
  • Good freeze thaw stability, with no creaming or severe oiling.
  • Good dilution stability, so that optimum concentration of silicone can be used with no excess waste.
  • Gives excellent finish to the mould.
  • Easily applied by brushing, dipping or spraying, even for complex moulds.
  • Low surface tension and easy wetting properties on the mould surface.
  • Highly economical - very small quantity required per release.
  • The film formed is durable and heat stable.
  • Imparts excellent shine & gloss to the moulded article.
  • Chemically inert - does not attack mould or moulding substances.
  • Low volatility - no fuming or smoking occurs.
  • It is non- - toxic and does not give rise to fumes.
  • Product viscosity can be adjusted to suit customer specifications.

Method Of Use

Mould Release is best used by being diluted with water to give a 0.5 % - 2 % active content. Higher concentration may be preferable under special circumstances. The diluted emulsion is best applied as a spray. Brushing is also feasible but may result in over application at some places. Application of excess quantities should be avoided as it may result in surface irregularities and poor welds. When spraying, it is recommended to adjust the spray nozzle to give a fine, barely visible fog, making a single pass across the full surface. The method is likely to give a number of releases per application.

New Moulds may be treated as follows

  • Apply concentrated Mould Release on the mould surface.
  • Heat to 250º to 260º C - hold for temperature for 60 minutes.
  • Cool the mould and athouroughly wipe off remaining excess oil.
  • Proceed with moulding operation as recommended above
