Before beginning the application process, you should always check whether the carrier material is suitable for Hotfix application.
Please check the following criteria:
- Heat resistance (min. 120°C/250°F)
- Resistance against pressure
- Application area of the product
- Suitability of surface properties and absorbency
Checking absorbency via the water drop test
The water drop test is a quick and easy way to get an initial idea of the absorbency of the carrier material.
Apply a couple of drops of water onto the carrier material.
If the material quickly absorbs the drops, it offers good absorbency.
If the water pearls off the carrier material, or if it takes a long time to be absorbed, the material offers insufficient absorbency.
This can impair the effectiveness of Hotfix application.

CrystAX Element Hotfix adhesive is activated within a temperature range of 120°C to 170°C (250°F to 340°F). A suitable application temperature can be selected from
With heat presses, the temperature selected on the display does not always reflect the actual temperature on the surface of the press.
Often, the temperature can be distributed unevenly, or one heat plate may be defective.
It is therefore recommended to regularly check the temperature with a laser measuring device or temperature measuring strips at various points on the heating surface, to ensure the temperature is distributed evenly across it.
Checks should be carried out regularly (once per week), particularly during production.

The pressure setting depends on the Hotfix elements to be applied, the carrier material, and the technical equipment (machines, etc.) available.
Too much pressure can cause the adhesive to be spread out and can also affect the surface of the carrier material.
Too little pressure, however, can result in a weak and insufficient bond between the crystal and the carrier material.
In general, the pressure should be applied directly to the crystal elements (e.g. Flat Backs Hotfix, Transfers, Crystal Mesh).
It is, therefore, necessary to check if there are any buttons, zippers or other raised parts surrounding them. Always use a compensating pad to even out the surface
When applying hotfix stone of different heights, a compensating pad should always be used. Silicone foam or foam rubber can be used here.
Application using a heat press
A heat press is an ideal tool for applying Hotfix products as it can be used to apply even, adjustable pressure.
mentioned in the product overview can be applied using the following steps.
Please also note the helpful hints concerning the application of Crystal Mesh and Diamond Transfers.
To adjust the application parameters and the aids to achieve an ideal balance, it is strongly recommended that tests are carried out with the original material.
1 Peel off the white protective film*.
2 Place the product in the desired position.
3 Make sure to apply the elements from the recommended side and use the correct pressing aid. To protect the heating surfaces from any glue residue, it is best to cover them with Teflon® film.
4 After the pressure, time and temperature
is set, close the heat press.
5 After the application is finished, use a pressing cloth to apply additional pressure to the product.
6 Once the product is at least hand warm, the transparent film can be removed at an acute angle
* Not all Hotfix products are provided with a protective or support film If adhesion is insufficient following the application process, it can be repeated, adjusting the parameters (such as pressure, time and temperature).
Please ensure that the application process is repeated from the very beginning and that the initial application time is combined with the additional time.
For example: After application, it is clear that the application time of 10 seconds was insufficient. Pressure should not just be applied for a further 5 seconds—the process must be repeated in its entirety, with an application time of 15 seconds.
