EpoxAcast® 650
|
EpoxAcast® 650 is a mineral filled general purpose casting epoxy that is low cost and versatile. It features a low mixed viscosity for minimal bubble entrapment. Choose Fast, Medium or Slow catalyst to fit your project. You can also use HT Hardener to give your castings higher heat resistance.
EpoxAcast® 650 is used for making hard dies for metal stamping as well as patterns and fixtures. It is also used for electrical encapsulation to extend the life cycles and enhance the performance of potted electronic devices. The high compressive strength of EpoxAcast® 650 makes it ideal for making stamping dies for production pressing of metal ornaments.EpoxAcast 650 Base (Part A) and Hardener (Part B) sold separately

EpoxAcast® 655
|
EpoxAcast® 655 (formerly Metalset® A-30) is a versatile aluminum filled castable epoxy that is very hard and strong. It is dimensionally stable, even when mass cast up to 512 in3/ 8,390 cm3. Different hardener speed options are available depending on your project requirements. Maximum heat resistance is achieved using HT HIGH TEMP hardener (up to 225°F/108°C).
Cured EpoxAcast® 655 epoxy has high physical properties and is used for a variety of applications including making hard tooling, vacuum forming dies/molds, injection molds, foundry patterns, jigs and fixtures and metal forming dies. Depending on project requirements, Part A Base can be mixed with 101 FAST, 102 MEDIUM, 103 SLOW or HT HIGH TEMP hardeners.EpoxAcast 655 Base (Part A) and Hardener (Part B) sold separately

EpoxAcast® 670
|
EpoxAcast® 670 HT (formerly 20-136) is an epoxy casting compound which offers high heat resistance up to 350° F/177° C if post cure schedule is used. EpoxAcast® 670 HT features a relatively low viscosity that ensures minimal bubble entrapment. EpoxAcast® 670 HT also offers an extra long working time of 3 hours.
Castings cure with negligible shrinkage and are very hard, very strong and heat resistant. EpoxAcast® 670 HT is ideal for making vacuum form molds, foundry patterns, forming dies & fixtures, hard rollers, industrial parts and high impact tools. EpoxAcast® 670 HT is also suitable for encapsulation applications or for use as a high temperature epoxy for bonding a variety of surfaces.

| Free Form® Air Epoxy Putty |
Free Form® Air Epoxy Putty
|
Free Form® Air is an extremely lightweight epoxy putty suitable for an infinite variety of industrial and art-related applications. This is a low-odor, low shrinkage putty that is unique, inexpensive and easy to use. Free Form® Air is mixed by hand with a 1A:1B by volume mix ratio. It offers a long working time and cures overnight at room temperature to a hard, rigid epoxy that is very strong with modeling board-like properties. Cured Free Form® Air is so lightweight, it will float in water. It can be sanded, shaped, drilled, tapped and CNC machined/routered. It will readily accept any paint. Free Form can also be color pigmented with SO-Strong® or Ignite® colorants.
After mixing, Free Form® Air can be pressed into a mold to make a lightweight, detailed casting. It will hold vertical surfaces and can be applied to almost any surface including polystyrene foam for rough sculpting. Free Form® putty can also be used to make rigid support shells or mother molds.
Epoxy Laminating; Laminate Free Form® Air putty in between layers of EpoxAmite® Laminating Epoxy and fiberglass cloth, carbon or other fiber for making lightweight composite parts. Eliminates the need to make multiple layers of laminating with liquid epoxy; saves time and labor. Epoxy Tooling Applications – use as a filleting material. Also good for jig and fixture construction. Used as a lightweight adhesive, Free Form® Air will bond to itself and a variety of surfaces including wood, stone and EpoxAcoat® Red surface coat epoxy. Free Form® Air will even cure under water. Pot Life/Working Time; this material is mass sensitive. The more material you mix at one time, the less time you have to work with it. Working tip; If mixing a large quantity, flatten putty with a rolling pin to reduce mass concentration and extend pot life.
- Thickness; 1.5 inch (3.81 cm) – pot life is 30 minutes, handling time is 2.5 hours, full cure in 24 hours.
- Thickness; 3/8” (0.95 cm) – pot life is 60 minutes, handling time is 4 hours, full cure in 24 hours.
- Thickness; 1/8” (0.32 cm) - pot life is 120 minutes; handling time is 8 hours, full cure in 24 hours.
