Casting, Potting, and Encapsulating Resins
Simply place your object in a mold, mix and pour Acrylic Plastic over it. In an hour it is hard and your object is firmly embedded in a clear, stable plastic. For high-gloss finish, it can be polished with a soft cloth.
Mold making and casting can be done in two hours. Acrylic Plastic Casting is a thermosetting acrylic-polymer plastic with excellent clarity and stabile characteristics.
The kit is available with 1 pint of resin and hardener, or 1quart of resin and hardener.

The Crystal Clear™ Series of polyurethane resins were designed for applications that require absolute clarity. These are low viscosity resins that cure at room temperature with negligible shrinkage to a hard plastic. Cured products are UV resistant and are not brittle. Applications include potting, encapsulating, making prototype models, and lenses, object duplicating etc.
CAUTION: This product is NOT for home use, for research and industrial use only.

Per the requests of our customers we are introducing a series of room temperature cured silicones that are used In the labs.
1. Blue Silicone Rubber
Blue Silicone Rubber is extremely high tear, high tensile strength, two components, and tin catalyzed RTV silicone rubber. It is designed for casting polyurethane foam, polyester and epoxy parts. It is a superior product with the following advantages over the RTV silicones:
- Extremely high tear strength
- Low shrinkage Low viscosity
- Excellent chemical resistance
- Excellent shelf aging
- Color coded catalyst
- Long pot life Insensitive to inhibition
- Variable cure rate
- Good dielectric properties
|Viscosity (cps)||50,000 – 70,000||300 – 400|
|Specific Gravity||1.10 .99|

2. Clear Silicone Rubber
This silicone cures at room temperature with no shrinkage and offers a unique water clear see through rubber with excellent tear strength, chemical and heat resistance.
|Hardness Shore A 6||40|
|Pot Life||60 min.|
|Demold Time||16 hours|
|Die B Tear Strength||120 pli|
|Tensile Strength||800 psi|
|Mixing Ratio Wt. Or Vol.||100:10 pbw|
Curing: allow the mold to cure overnight (at least 16 hours) at room temperature (77°F/25°C) before demolding. Do not cure rubber where temperature is less than 65°F/18°C. Post Curing the mold will aid in quickly attaining maximum physical and performance properties. After curing at room temperature, expose the rubber to 80°C for 2 hours and 100°C for 2 hours. Allow mold to cool to room temperature before using
NOTE: This clear silicone will cause rubber to yellow when applying post curing.
Ordering: Clear silicone comes as a kit of 1gallon (9 lb) silicone A and 1 pt (.9lb) curing agent B.
