Release Agents for Moldmaking and Casting

Ease Release™ 200 and 205

Ease Release™ 200 and 205 is an excellent general purpose release agent for making molds and casting parts. This product will release urethane rubber, urethane resins, polyester resins, RTV silicones, and thermoplastic polymers. Ease Release™ 200 and 205 is effective on urethane, silicone and metal molds.

Ideal For Releasing:

Urethane Rubber From Original Models
Urethane Plastic From Urethane Rubber
Silicone Rubber From Original Models
Silicone Rubber From Silicone Rubber
Urethane Plastic From Silicone Rubber

NOT FOR USE WITH URETHANE FOAMS
For releasing foam, use Ease Release 2831.

200 is an aerosol, 205 is a bulk liquid.

Universal Mold Release

Universal Mold Release™ is formulated especially for mold making and casting, and works well with most liquid rubber and liquid plastic products. It will release mold rubbers (such as polyurethanes and polysulfides) from properly prepared models. Sealing porous models (wood, plaster, concrete) or certain modeling clays (containing water or sulfur) with Smooth-On SuperSeal™ or other sealer may be necessary. If using silicone rubber, seal model surface with SuperSeal™ only. Do not use UMR.

UMR also easily releases a variety of casting materials (epoxies, Smooth-On liquid plastics, etc.) from cured rubber molds. Properly used, Universal Mold Release improves molding efficiency for a variety of casting applications and will actually lengthen the life of your production mold.

NOT FOR USE WHEN MOLDING SILICONE RUBBER OR CASTING URETHANE FOAM
For silicone rubber, use Ease Release 200
For urethane foam, use Ease Release 2831

Available in aerosol or bulk liquid.

In & Out™ Concrete Release Agent

IN & OUT™ II water soluble release agent will aid in releasing concrete or gypsum plaster castings from Smooth-On rubber molds. IN & OUT™ II provides a clean, positive release and does not interfere with or affect surface detail and helps minimize air bubbles in finished castings.

Simplify Your Production Casting With IN & OUT II™

Will Not Stain / Soften Concrete Or Gypsum Surfaces
Mix With Water - Economical
Will Not Affect Color Pigmenting Of Cast Concrete
Minimizes “Bug Holes” In Concrete And Air Bubbles In Gypsum Castings
Keeps Molds Clean - Does Not Build Up
Significantly Extends Mold Life

IN & OUT™ II Water Soluble Release Agent IN & OUT™ II IS DILUTED WITH WATER. Mix 4 parts water to 1 part In & Out™ II. Mixing can be done by hand or slow speed mixer. Do not shake or agitate as this may cause product to foam. How you dilute IN & OUT™ II (amount mixed with water, coverage and frequency of application) will depend on the concrete aggregate mix and the form material you are casting into. For example, when casting concrete with a low grit/high sand content (minimal abrasion) into a polyurethane mold, the mix ratio of water to IN & OUT II™ can be 4 : 1. High grit content may call for a dilution ratio of 2 parts water to 1 part release agent. Mix only amount needed for one day. Mixture may separate after 24 hours. Re-mix to a uniform consistency and apply.

Ease Release™ 2831
Ease Release™ 2831	Ease Release™ 2831 is a wax-based non-silicone liquid release agent. It has proven to be effective when used to release polyurethane foams. This wax dispersion is designed to operate at mold temperatures ranging from 160°F to 200°F with minimal wax build-up. EASE RELEASE 2831 works with aluminum, steel, and elastomeric mold construction. This product may incur a UPS ground hazard shipping fee.
