PLATSIL GEL 00

Prior to use, ensure that both Parts A & B are at room temperature (ideally surface & air temperature should be above 60°F during application and for the entire curing period).

Carefully measure or weigh Part B and then Part A (in proper ratio) into a clean mixing container. Mix thoroughly, scraping sides and bottom of the container. The mix should be quickly placed over the model or in the mold.

If more working time is needed, PlatSil® 71/73 Part R Retarder can be used.

Mold Making:

Seal any porous models (e.g: wood, plaster, etc) with wax, petroleum jelly, lacquer or paint to prevent penetration of the rubber into the pores of the material.

Both the model and any other surfaces that come into contact with the Plastsil should be coated lightly with a Release Agent. (Do not use silicone-based release agents on surfaces that contact liquid PlatSil rubbers since inhibition and/or adhesion may occur. In addition, modeling clays containing sulfur will inhibit curing.

Contamination with soaps, amines, sulfur, tin compounds, polyester resins and some silicone rubbers can also inhibit surface cure.

PlatSil rubber may bond to cured silicone rubber unless a parting agent is used. If in doubt, test cure on a similar surface to ensure proper cure and release.

Porous models should be vented from beneath to prevent trapped air from causing bubbles in the rubber.

For best results, the PlatSil Gel mold should be allowed to cure for the specified demold time before it is put into use. No release agent is necessary for casting most materials in properly-cured PlatSil Gels. For longer mold life when casting epoxy, polyurethane or polyester resins, a barrier coat or release agent is recommended.
