Epoxy Resin

The basic Scotchcast™ epoxy resins products include flexible, semi flexible and rigid room-temperature curing and oven curing epoxy resin, some of which are then modified to create filled and thixotropic versions. Other subdivisions, based on temperature, class, colour and special formulations, complete the product line.

All Scotchcast epoxy resin products are formulated and produced for convenient and reliable use. Simple mixing ratios and preproportioned packaging allow for easy handling and mixing, and reduce errors on the production line.

Applications

  • Dipping
  • Potting
  • Casting
  • Impregnation
  • Troweling

Selecting Your Epoxy Resin


The Scotchcast™ epoxy resin most likely to succeed in an application can be selected through a process of elimination. Simply answer four basic questions (click over each for more information)

Room Cure or Oven Cure? Filler? Temperature Class? Degree of Flexibility?
In answering this question, consider:
  • The availability of ovens. If unavailable, or if their purchase cannot be justified by application, volume, or rate requirements, a room-temperature curing resin must be selected.
  • The application process. From a production and engineering standpoint, oven cures are more versatile than room cures because they have long pot lives, short cure times and their viscosities can be lowered by warming.
  • The number of units to be processed. Oven-curing resins are usually used in high-volume applications because they are less expensive than their room-curing counterparts. The expense of ovens is offset by a decrease in resin cost.
  • The mass of resin to be used per unit. Room-curing resins rely heavily on the heat generated from their reaction for completion of cure. In large masses the resin could act as a heat insulator and cause the interior temperature to rise rapidly. If uncontrolled, this rise in temperature could exceed the maximum temperature some components can tolerate. A high exotherm could also cause the resin to crack or char. If a large mass of a roomtemperature curing resin must be used, the exotherm problem can be overcome by curing the mass in layers and allowing each layer to cool before casting the next.

The following selection guide  provide some additional information that may be used to determine the answers to the above four basic questions. Alternatively use the table below to help you.

Polyurethane Resins
Polyurethane Resin 226 is used for a wide range of electrical and electronic potting and casting applications. For example, its low exotherm and low cure shrinkage, make possible the potting of small, heat-sensitive components, as well as the casting of large quantities of the resin at one time. And the very low viscosity of the product makes it possible to quickly fill and impregnate sand-filled modules.
