Epoxy Casting Resins

Room Temperature

EC-426 Abrasion Resistant Die Surface Cast, Medium
EC-426-2 Abrasion Resistant Die Surface Cast, Slow
Abrasion resistant, room temp systems developed for casting hard surface tools and dies. Excellent air release. High physical properties. Detailed, durable, void-free and dimensionally accurate duplications. Cast EC-426 up to 3/4" and EC-426-2 UP to 4" without excessive exotherm or shrinkage. Use with ES-204,  ES-204 SC when adding N-20 Bulk Aluminum Filler to facilitate thicker castings.

EC-428 Aluminum Filled, Room Temp, Moderate
EC-428-1 Aluminum Filled, Room Temp, Slow
Cast up to 3/4" or 2-4", respectively. Will not settle during shipment or storage. Designed for low exotherm curing to increase dimensional stability with minimal shrinkage. High strength and durability. Use with ES-204, ES-204 SC or ES-219 when adding N-20 Bulk Aluminum Filler for thicker castings.

High Temperature

EC-433-2 Aluminum Filled, High Temp, Fast
EC-433-3 Aluminum Filled, High Temp, Medium
EC-433-4 Aluminum Filled, High Temp, Slow
Versatile systems developed for heat resistant tooling. Room temp (B stage) hardening systems which require post cure for use above 66°C/150°F. Continuous use of tools at 160°C/320°F and intermittent use up to 191°C/375°F, with consistent strength and impact properties. Three systems offer the toolmaker alternatives for casting thickness. Use with ES-219 Surface Coat when using N-20 Bulk Aluminum Filler for casting larger masses.

EC-439 High Temperature, Unfilled
A low viscosity, unfilled epoxy casting system that can be used with a variety of fillers for many different applications. This system offers a moderate work life and heat resistance to 300° F after only a 150°F postcure. EC-429 is not designed for use as a stand-alone casting system. Use with ES-215 or ES-219.

EC-439 High Temperature/Ceramic Filled
A four component, ceramic filled epoxy casting that is designed to function as a stand alone mass casting system, and can be used in place of more expensive aluminum filled casting materials. EC-430 offers the user low CTE, high HDT, long work life and excellent thermal conductivity. Can be used as a back up material for nickel shell or behind high temperature epoxy surface coats. Use with ES-215 or ES-219.
