ProtoCast Series
Rigid Casting Compounds
Casting compound resin for the look and feel of injection molded high definition-prototype parts. This is a low viscosity, rapid setting, rigid urethane resin which cures quickly to a hard, tough impact resistant casting, with a thermoplastic feel. Protocast is non-sensitive to moisture after cure and will bond to itself if stage pours are required. This product eliminates the need for expensive metal injection molds.
Protocast has been specially formulated for casting high definition or 3 dimensional prototype parts or limited run production work for the look and feel of thermoplastic. This product will not become brittle when used to mold a thin walled part. These products maybe hand or machine mixed. Various curing and work times are available. Hardness range from 60 Shore D to 85 Shore D
These products feature:
- Rapid setting and demold times
- Excellent machinability
- Easily drilled and contoured with conventional sanding equipment
- Recommended in applications where a “thermoplastic feel” is desired
- Easily hand mixed or machine dispensed
Applications and Uses
- Excellent for molding thick or thin section rigid parts
- Electrical Encapsulations
- Thermoplastic “like” casting
- Machinable
- 3-dimensional prototype parts
- Limited run production work
Specific Applications
Rigid Casting Compounds
ProtoCast 80-R
Our rigid casting urethanes offer a variety of densities, hardness and working life to fit your application. Silicone rubber, aluminum, polyurethane or epoxy molds can be used for casting these products. A mold-releasing agent such as spray silicone or wax may be required to prevent bonding of these products to your molds. Our rigid castings urethanes are designed for easy hand mixing, no heating or cooking is required simply mix and pour into your mold.
Product Features:
- Rapid setting
- White color when fully cured
- Low Viscosity
- Convenient 1 to 1 mixing ratio by volume for machine dispensing or hand mixing
- Can be colored
- Rapid Cure
- Fast working life (3-5 min))
Product Uses:
- Excellent for molding thick or thin section rigid parts
- Electrical Encapsulations
Impact Resistant Low Viscosity Castings
ProtoCast 100
Product Features:
- Rapid setting
- Amber color (semi translucent)
- Low Viscosity
- Convenient 1 to 1 mixing ratio by volume for machine dispensing or hand mixing
- Can be colored with pigment or dyes
Product Uses:
- Excellent for molding thick or thin section rigid parts
- Electrical Encapsulations
Thermoplastic “Feel” Casting Compound
ProtoCast 410
Protocast 410 is a very low viscosity, rapid setting, and rigid urethane compound. This system will cure quickly to a hard, tough impact resistant casting. Protocast 410 is non-sensitive to moisture after cure and will readily bond to itself, as stage pours are required. The 1:1, by volume, mix ratio makes for easy hand or machine mix. Protocast 410 is recommended in applications where a “thermoplastic feel” is desired, not “brittle” in thin walled parts.
Product Features:
- High resistance to impact
- High strength and durometer
- Rapid setting
- Low Viscosity
- Convenient 1 to 1 mixing ratio by volume for machine dispensing or hand mixing
- Color: Black, other colors available
Product Uses:
- Excellent for molding thick or thin section rigid parts
- Molding rigid parts with higher resistance to impact and mechanical abusets
