The auxiliary material indispensable for metallographic cold embedding is undoubtedly a release agent, and without it, it is difficult to remove the embedded sample from the mold. However, the commonly used release agents are hazardous chemicals, with odors and some may be slightly toxic. They need to be used in a fume hood, and operators need to wear corresponding protective equipment, such as masks, goggles, gloves, etc. There is also a storage issue, and only qualified laboratories can store release agents that belong to hazardous chemicals, which also brings a lot of trouble to some laboratories. However, the release agent for QMAXIS non hazardous goods imported from the United States has arrived with a small brush, and it is easy to release with just a flick!

QMAXIS release agent imported from the United States, Release agent? Release agent, made of silicone, odorless and non-toxic, is a non hazardous chemical metallographic embedded release agent. Therefore, it can be stored even if the laboratory does not have relevant qualifications.


The QMAXIS release agent in the United States fully considers the convenience of user use and has designed five packaging specifications in terms of size. It is used as a large bottle packaging for storage and a small bottle packaging for use. The cap of the small bottle comes with a small brush, making it very convenient to use.

When inserting the sample, pinch the bottle cap by hand, use a small brush to dip an appropriate amount of release agent, gently apply it to the bottom and inner wall of the injection cup, evenly apply a thin layer, which is just right. Wait for a moment, and let the surface dry before placing the sample at the bottom of the cup. Then, inject a mixed mixture of inlay resin and curing agent into the injection cup. When the sample is fully cured and can be removed, invert the injection cup onto the experimental bench, Take out the sample with a gentle tap, isn't it super easy to use!

Our laboratory currently uses QMAXIS demolding agent and other inlay consumables that can be detected by pulse testing. The reason for using such a good demolding agent is because we purchased a vacuum penetrometer that can be detected by pulse testing. At that time, we randomly brought a complete set of cold inlaying resin and curing agent, as well as injection cups, wax paper cups, stirring rods, and demolding agents. After use, we found that this demolding agent is not only useful, but also not dangerous! So share it with friends, hoping to be helpful to friends who are doing metallography!
