This product has a limited shelf life and should be used as soon as possible. Mixing should be done in a well-ventilated area. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. If making a 2 or more piece mother mold, apply appropriate shim apparatus to rubber mold exterior.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBecause no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eApplying A Release Agent\u003c\/strong\u003e\u003c\/em\u003e – This product is adhesive and will bond to many surfaces. A sealer followed by a release agent is necessary to facilitate demolding when applying as a mother mold over a cured mold rubber. Use \u003cstrong\u003eSonite™ Wax\u003c\/strong\u003e followed by a coating of \u003cstrong\u003eUniversal™ Mold Release\u003c\/strong\u003e or \u003cstrong\u003eEase Release™ 200\u003c\/strong\u003e release agent. A liberal coat of release agent should be applied onto all surfaces that will contact the plastic.

The first will be used for measuring out amounts of Part A and Part B. The second should be large enough to contain both components and allow thorough mixing. \u003cstrong\u003eIMPORTANT: \u003c\/strong\u003eShelf life of Part A (Yellow Container) is reduced after opening.

Level off the top of the container and remove any excess material. The paste should then be thoroughly emptied into a larger container that will act as your mixing container. Repeat As Necessary. \u003cstrong\u003e(Step 2)\u003c\/strong\u003e Fill the measuring container to the top with Part A liquid and empty into mixing container. Mix thoroughly for 2-3 minutes making sure that you scrape the sides and bottom of the mixing container several times. Eliminate color streaks. \u003cstrong\u003eIf adding So-Strong™ color tints,\u003c\/strong\u003e pre-mix color with the Part B before adding Part A.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eMixing Large Batches \u003c\/strong\u003e\u003c\/em\u003e- A ‘Turbine’ mechanical mixer attached to a power drill will make mixing large batches of material much easier.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e\u003c\/em\u003e Shelf life of product is reduced after opening. Remaining product should be used as soon as possible. Immediately replacing the lids on both containers after dispensing product will help prolong the shelf life of the unused product. \u003cstrong\u003eXTEND-IT™ Dry Gas Blanket\u003c\/strong\u003e (available from Smooth-On) will significantly prolong the shelf life of unused liquid urethane products.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eApplying\u003c\/strong\u003e\u003c\/em\u003e – Mixed material thickens quickly and pot life is limited. Do not delay between mixing and applying. To increase working time, spread entire container contents over rubber mold surface and cover and spread mixture to uncovered areas. Apply uniformly with spatula over mold surface. Material will adhere to itself if additional layers are needed. Apply at least 3\/8” (1 cm) thickness, making sure rubber mold is thoroughly covered.\u003cstrong\u003e For maximum strength \u003c\/strong\u003eand heat resistance, ½” (1.27 cm) thickness is recommended. Large molds may require added thickness for support shell stability. Supports (wood or metal) may be embedded for added stability and handling.\u003cstrong\u003e Prevent a jagged surface;\u003c\/strong\u003e Final layer of \u003cstrong\u003ePlasti-Paste™ II\u003c\/strong\u003e can be smoothed by wiping solvent (denatured alcohol or acetone) onto surface with gloved hand.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eMaking A Two Piece Shell \u003c\/strong\u003e\u003c\/em\u003e– \u003cstrong\u003ePlasti-Paste™ II\u003c\/strong\u003e will bond to most surfaces and itself tenaciously. A barrier coat of paste wax followed by \u003cstrong\u003eUniversal™ Mold Release\u003c\/strong\u003e applied to all surfaces is necessary to prevent adhesion. Applying aluminum foil to the contours of all surfaces followed by \u003cstrong\u003eUniversal™ Mold Release\u003c\/strong\u003e will also prevent adhesion.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eIf You Want To Paint Cured Plastic\u003c\/strong\u003e\u003c\/em\u003e – For best results, measure 62 Parts A + 100 Parts B by weight using a gram scale.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eCuring\u003c\/strong\u003e\u003c\/em\u003e – Plastic will be hot immediately following cure. Let cool to room temperature before handling. Material will develop handling strength and can be handled in about 90 minutes depending on mass. At this point, it is stable enough to demold, re-assemble over rubber mold and make a casting (hold 2 or more piece assemblies together with elastic bands, mold straps or bolts). Large sections should be bolted together to minimize distortion. Full strength develops in 24 hours.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eHeat Resistance\u003c\/strong\u003e\u003c\/em\u003e – Fully cured plastic with a minimum thickness of ½” (1.27 cm) will resist temperatures up to 130°F\/55°C. To improve heat resistance to 158°F \/ 70°C, post cure material at 150°F\/65°C for 16 hours.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIf machining or sanding cured plastic, wear NIOSH approved mask to prevent inhalation of residual particles.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003ePainting \u003c\/strong\u003e\u003c\/em\u003e– Make sure surface is clean and free of release agents or other contaminants.

Demold time (can be handled) is about 90 minutes at room temperature depending on mass. Full cure; 24 hours at room temperature. Cure time can be accelerated by applying heat.\u003c\/p\u003e\n\u003cp\u003eMixed material holds a vertical surface without sagging and cures to a strong, durable and lightweight plastic. Liquid material can be pigmented with \u003cstrong\u003eSo-Strong™\u003c\/strong\u003e color tints from Smooth-On. This plastic can be used for creating themed environments or special effects, used as a “mother mold” material to reinforce rubber molds and a variety of other applications. \u003cstrong\u003eThis plastic is also a powerful adhesive\u003c\/strong\u003e and can be used as a repair material for a variety of industrial applications.
