Activated Chemical/Mechanical Purging Compounds
RapidPurge Activated Chemical/Mechanical products are the ones that made us famous for supplying the most effective purging compounds available. These products include chemical agents that break down the molecular structure and viscosity of the resident resin. They also include an expanding foaming agent to reach negative flow areas, and mechanical compounds to soft polish the base metal.
Activated Chemical/Mechanical products come in various grades to match your temperature and viscosity requirements, and they are available in convenient pre-mixed form and as concentrates.

RapidPurge "no resin" products are ideal for particularly sensitive applications such as auto lamp lenses, where the introduction of a foreign resin during the purge process poses a problem. These products come in three variations including a basic purge, a purge with a heat-activated foam for negative flow areas, and a chemical/mechanical purge that is comparable to our premium Activated Chemical/Mechanical products for challenging purge applications.
"No Resin" products include no resin of their own, and are mixed with your resident resin which serves as the carrier during purge.

Activated — Filled Resin Purging Compounds
RapidPurge Activated — Filled Resin products are concentrates specially formulated for applications with a filled resin, such as glass-filled resin.
Activated — Filled Resin products come in two versions: a mechanical compound that includes a foaming agent to reach negative flow areas, and a chemical/mechanical formulation for more difficult purging applications.
If you have a special need, RapidPurge is the only purge supplier that will work with you to mix a custom blend to meet your exact requirements.
Pre-mixed Compounds
For the ultimate in convenience and ease of use, most RapidPurge products are available in a ready-to-use pre-mixed form that includes a universal carrier resin.
Concentrated Formulations
Many RapidPurge compounds are available in concentrated form. Using your own carrier resin, these concentrates are convenient and cost-effective.
