Additives compatible with Smooth-On Platinum Catalyzed Silicones for altering and enhancing the characteristics and performance of the rubber compounds. Choose from a variety of colorants, cure accelerators, thinners or thickeners, adhesives and more.
Color pigments are used for coloring Smooth-On's silicone rubber compounds including the Dragon Skin™ Series and Ecoflex™ Series. SilcPig™ pigments offer excellent dispersion and consistent color and Silc Pig™ Electric Fluorescent Pigments are a line of liquid fluorescent colorants.
Thickening agent for Smooth-On silicone rubber for vertical surface application (making brush-on molds). Different viscosities can be attained by varying the amount of THI-VEX™ added as a small percentage of Part A.
Make it Brushable
Easy to Modify
Translucent liquid additive that causes cured Smooth-On silicone rubbers, urethane rubbers, plastics or foams to glow a bright blue under a focused ultra violet light source (blacklight). When mixed at low percentages it will not affect clarity or color of material and the glow effect will not be evident until the casting is illuminated by a UV light source.
Scale Not Required
Slacker™ is a one component translucent clear fluid that is added by volume or weight to Smooth-On's translucent platinum-cure silicones such as Dragon Skin™ and EcoFlex™ products. Slacker™ will change the “feel” of the silicone rubber to a softer and more “flesh-like” material. It also alters the rebound properties of the silicone, making it feel more like human tissue.
No Scale Required
Easy to Modify
NOVOCS™ are low viscosity silicone solvents that contain no VOC’s and evaporate quickly. NOVOCS™ solvents can be used to shrink or enlarge silicone rubber molds. NOVOCS™ Gloss will leave a gloss finish and NOVOCS™ Matte will leave a matte finish on the surface of cured silicone rubber props.
WARNING - FLAMMABLE Liquid and vapor. Keep away from ignition sources and follow precautions for handling flammables.
Gram Scale Required
Silicone Thinner™ is a non-reactive silicone fluid that will lower the mixed viscosity of tin cure (condensation) or platinum cure (addition) silicone rubber products. This means that the rubber will de-air faster when vacuuming and will flow better over intricate model detail.
Gram Scale Required
Plat-Cat™ Platinum Silicone Cure Accelerator is an additive designed to “accelerate” the cure time of Smooth-On platinum silicones. Slo-Jo™ Platinum Silicone Cure Retarder is designed to extend the pot life (working time) of Smooth-On platinum silicone rubber and Soma Foama™ silicone foam. Using these additives will not affect the ultimate physical properties.
Gram Scale Required
SLIDE™ STD Liquid Surface Tension Diffuser is an additive for platinum cure silicone rubber that creates a cured silicone piece with greatly reduced surface tension. Cured silicone slides across itself and different surfaces. Silicone surface must be exposed to air for 24 hours to bring out slide effect.
Gram Scale Required
Inhibit X™ is a single component, low-viscosity liquid that provides an added measure of protection against cure inhibition when pouring platinum silicone rubbers over many surfaces including spray adhesives, tapes, wood surfaces, some plastics, SLA resins and others.
Sil‑Poxy™ is a one component adhesive made specifically for bonding RTV silicone rubber to silicone rubber and other substrates including some plastics (urethane), plasters/ceramics, fabrics, etc. Sil‑Poxy™ can be used repairing torn silicone rubber molds.
Fast Cure
Skin Tite™ is a skin safe silicone used to create fast wounds, scars and to adhere skin effect appliances directly to the skin. It can be sculpted “on the fly”, offers maximum control and stays precisely where you put it. Cured rubber is strong and will bend/flex with body movement. Wounds and appliances will not come off until you remove them. An infinite variety of color effects are achieved using Silc Pig™ silicone pigments.
Easy To Color
Easy To Modify
Certified Skin Safe
Skin safe pressure sensitive adhesive designed for temporarily adhering silicone and latex makeup prosthetic appliances to the skin. This is a low odor formulation which is cosmetic grade and non-irritating. Use Derma-tac™ Remover to dissolve Derma-tac™ and aid in removing appliances from the skin.
Certified Skin Safe
Temporarily adhere most surgical tapes, bandages, dressings, etc. to silicone rubber surfaces including training mannequins, devices, etc. This non-VOC formula is a low viscosity liquid that brushes on easily and dries quickly. One application lasts for repeated use.
