Frequently Asked Questions about Digesil

What is Digesil used for?

Digesil is used to remove cured silicone (GE, Dow, Rhodia, NuSil, Wacker) and other tenacious sealants and adhesives.

How does it work?

Digesil penetrates the polymer to cleave it into smaller parts emulsifying the polymer.  This emulsification prevents re deposition and enables easy rinsing.

Can Digesil be used as a degreaser?

Yes.  However, we recommend TRAMOS as a more economical degreaser.

How long does it take to work?

This depends on the type of polymer, thickness of the polymer, temperature, agitation, and age of the Digesil.

Is it hazardous for transportation?

No. Digesil is not hazardous to ship.  Digesil contains no EPA Listed ingredients.

Is it a solvent?

Yes and no.  Digesil does not dissolve silicone like sugar dissolves in water.  The Digesil actually breaks the bonds of the silicone into small parts so that it can emulsify.

Can it be used in parts washers or ultrasonic tanks?

Yes.  Digesil is compatible with numerous metals and plastics.  Ultrasonics actually decreases the amount of cleaning time by 75%.  Heat, up to 49°C (120°F), can also be used to decrease cleaning time by 50%.

Will temperature effect performance?

Yes, elevating the temperature of the Digesil will improve its performance.  See above.

How do I know when it is not working anymore?

When the item/part no longer gets clean in the typical cleaning time for your particular application.  When you first start using Digesil, it is worthwhile to note the initial cleaning time for reference and comparison.

How do I dispose of it?

Digesil may be disposed of with your other solvents.  The material does have a high heating value and can be burned for fuel value.

Can it be filtered?

Yes, Digesil can be filtered and this is recommended to extend the life of the material.  A 10-micron filter is usually sufficient.

Can it be reused?

The Digesil can continue to be used until it no longer digests the sealant.  Once the material no longer works it must be disposed.

Does it smell?

Digesil has a very slight odor.  As the ingredients are not listed, no special breathing apparatus is required.  However, we do recommend using in a well-ventilated area.

Do you have to wear breathing apparatus?

No, see above.

Will it remove epoxies?

Digesil will remove some epoxies.  The best way to determine this is to send RPM Technology a sample of the material you want to remove so we can determine which solvent is best for your application.
