#4113 Fast Set Tooling / Prototyping Urethane Kit is a two-part urethane casting system for molds or parts. This metallic grey urethane cures rapidly, so it can be mixed, poured, and demolded very quickly. Most castings made with #4113 Fast Set Tooling / Prototyping Urethane Kit can be demolded in 30 to 40 minutes and can be put into service within a day.

With low shrinkage and low exotherm during cure, this stable urethane kit is ideal for making medium to large complicated casts. Use this smooth, easy-pour system to quickly create tooling, patterns, molds, fixtures, and much more. This urethane has outstanding cured properties including: heat resistance, exceptional hardness, and excellent cured stability.

#4113 Fast Set Tooling / Prototyping Urethane Kit has a simple 1:1 mix ratio by weight or volume. Once mixed, this urethane has a 5-6 minute pot life. Pour the urethane very slowly to aid the release of air bubbles. When using #4113 Fast Set Tooling / Prototyping Urethane Kit, avoid water and all types of moisture contamination. Do not use this urethane kit with PVA Release Film. To ensure a proper release from a mold, use at least four layers of #4121 Non-Silicone High Temp Paste Wax.

• Mix Ratio – 1:1 (by weight and volume)
• Color – Gray
• Pot Life, 4 fl. Oz. Mass, @ 77°F – 5-6 minutes

This Non-Silicone High Temp Paste Wax is designed to release epoxy and polyesters, and can be used in application temperatures ranging from 75°F to 375°. This smooth, creamy paste wax can be applied to polyester, epoxy, steel, and aluminum molds and the non-silicone nature of this wax prevents any silicone contamination.

Before molding for the first time, make at least three applications of #4121 Non-Silicone High Temp Paste Wax, 4 to 6 hours apart. Select an area of about 4 square feet. Using a circular motion, apply #4121 with a clean, dry terry cloth towel. With a separate, clean towel, break the surface film before it dries. After waxing the entire surface, buff with a clean towel until the wax is clear.

The #1782 is softer, more durable and pliable than our low temperature release films. It does not tear easily and can be used up to 500°F. This vacuum bagging release film does not have any perforation, unlike one of our low temperature release film. The resin content can be more closely controlled by using this solid release film and a known amount of resin in your wet layup or prepreg.

It is compatible with epoxy, phenolic, vinyl ester, polyester and most other resin systems.

This high temperature release film is 60" wide

3K, 12x12, 5.7 oz/sq yd, 50" Wide. This pattern captures the sophisticated appeal of a chessboard and the excitement of a checkered flag. This fabric has multiple dimensions. At certain viewing angles, this pattern has a high-contrast chessboard look. At other viewing angles, each square turns into a subtle diamond. Use this carbon fiber to achieve an exceptionally unique part.

This first quality, hybrid fabric offers 3K Carbon in the warp and 1420 Denier KEVLAR® in the fill directions for maximum drape and drop-dead good looks. Use as a single layer for cosmetics or back with another layer in the cross direction for a maximum balance of properties. The KEVLAR® fibers are dyed with a yellow dye for eye-catching color. This Hybrid of KEVLAR® and Carbon offers the best of both worlds by offering the properties of both materials in each layer. Some of the benefits are a high strength-to-weight ratio, high conformability, impact resistance, abrasion resistance, dimensional stability, fatigue resistance, and fire resistance. The fabric is compatible with Polyester, Vinyl-Ester, and Epoxy resin.
