Acrylic Resin

Acrylic resins, including Aka-Clear-2 cure in a catalytic process. Therefore it is not necessary to have very precise amounts of powder and liquid.

Very often the reason is a chemical reaction of the mounting resin with air. If you cover your mount e.g. with a piece of paper or a small lid this can be avoided.

The curing time, and such the pot life of acrylic resins is quite short. Therefore it is recommended to mix smaller batches of resin to avoid that curing already starts while pouring the resin into the mounting cup.

To minimise air bubbles, consider these tips:

• Add slightly more liquid than the standard ratio to make the mixture easier to pour and ensure it fills all voids.
• After pouring, gently tap or knock the mould on the table to release trapped air bubbles.
• For small voids, dip the sample into the liquid before embedding it in the mould.
• If large voids occur, they can be filled by carefully grinding and cleaning the mount, then applying a thin layer of mixed resin over the surface​.

Although the curing process for Aka-Clear-2 generates heat (up to 90°C), it is classified as a cold mounting resin because it cures at room temperature without requiring additional heating equipment. This convenience makes it ideal for a wide range of applications, including heat-sensitive samples​​.
