Application Techniques

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.

Some textiles and special finishes are unsuitable for Hotfix application, due to a lack of absorbency.

This is a list of unsuitable carrier materials and finishes:

- Very tightly woven textiles

- Very thin fabrics, e.g. organza

- Smooth leather and smooth imitation leather. 

- Hydrophobic or water-repellent treatments (silicone, synthetic resin as a waterproofing agent)

- Teflon coatings

- Stain-resistant treatments

- Easy-to-care treatments

- Fluorocarbon finishes

- Softening agents

- Select dyes (dyes with metal pigments)

-  Enzymatic treatments It can sometimes be helpful to wash the carrier material before application, in order to remove any unsuitable finishes (particularly softening agents), and thus improve absorbency.

Generally, the following parameters are most important when carrying out Hotfix applications. 

- Temperature
- Pressure
- Application time
- Application side A detailed summary of all application parameters can be found in the Hotfix Selector table at the end of this chapter.





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 this  range according to the carrier material and its sensitivity to heat.

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.
All Hotfix Rhinestones    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.

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.

5 After the application is finished, use a pressing cloth to apply additional pressure to the product.

* 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.
