Mold Max^® 15T & 27T silicones can be used to cast a variety of materials including wax, gypsum, low melt alloys/metals and urethane, epoxy or polyester resins (without using a release agent). A gram scale or triple beam balance is essential when using these products. Mold Max^® 15T - Shore 15A hardness Mold Max^® 27T - Shore 27A hardness

Mold Max® STROKE Brushable Tin-Cure Silicone

Mold Max Stroke^® is a brushable tin silicone rubber that self-thickens for making fast brush-on molds of almost any model. Properly applied, it will hold a vertical surface and will reproduce the finest detail.

Mixed 100A:10B by weight, rubber quickly develops thixotropy and can be applied with a brush or spatula. Working time is 20 minutes, re-coat time is 45 minutes and cure time after the final layer has been applied is 16 hours at room temperature. Mold Max Stroke^® silicone will not stick to most surfaces and will cure with negligible shrinkage to a strong, flexible Shore 30A rubber.

4 thin layers is all that is necessary to make a strong and durable production mold for casting wax, gypsum, concrete or resins (urethane, polyester, etc.). Applications include reproducing sculpture, architectural restoration, making candle molds, casting pewter, etc.

Encapso K® Water Clear Encapsulation / Display Rubber

Encapso^® K is a water clear encapsulation rubber that looks just like water and is ideal for a variety of encapsulation and display applications.

How Does Encapso^® K Work? - Two clear liquids (Part A and Part B) are mixed together in equal amounts. The mixture is then poured around artificial flower stems or over an object. Mixture turns from liquid to a solid, soft rubber over night. When cured, Encapso^® K looks just like water and will last a long time.

Encapso^® K Advantages;

• Non-Hazardous - No dangerous chemicals
• Soft, Clear Rubber Lasts A Long Time
• Easy To Use - Mix two liquids in equal amounts and pour
• UV Resistant
• Cures without generating any dangerous heat or fumes
• Minimal Bubble Entrapment
• Cures perfectly clear - Looks just like water
• Cured rubber can be removed from object

Applications for Encapso^® K

This rubber is perfect for encapsulating artificial flower stems for creating lasting floral displays. You can also pour Encapso^® K around just about any inanimate object to encapsulate for display. You can also create a variety of display props and novelty items. Encapso^® K can be used to create water/pond effects for small scale model environments. Fully cured Encapso^® K can also be crumbled to look like broken glass, diamonds or ice. Add color to Encapso^® K with Silc Pig^® or Ignite^® liquid color pigments.

Rubber Glass™ II For Flexible Glass & Ice Effects
Rubber Glass™ II For Flexible Glass & Ice Effects	Rubber Glass^TMII is an improved tin-catalyzed silicone rubber product developed specifically for special effects and display applications. Two liquids (3 Parts A + 1 Part B) are mixed together and poured into a container. The mixture cures overnight to a solid water clear rubber that can then be easily broken or “crumbled” into pieces that look exactly like broken glass, ice or diamonds. Vibrant colors are possible by adding SilcPig^TMliquid color pigments. Rubber Glass^TMII is can be used to create a variety of special effects (i.e. simulated broken glass where human contact is required) and model effects (i.e. simulated ice or water). It can also be used for electronic encapsulation applications. How is this new formula an improvement over the original Rubber Glass? 1. Rubber Glass^TM II is clearer 2. Rubber Glass^TMII crumbles into pieces that more uniformly look like broken glass, ice or rough diamonds 3. Rubber Glass^TM II is less expensive than the original formula.
