FLAT BACK STONES

Preciosa Flat Back Stones are easily applied to a wide range of materials; whether you are gluing, hot-fixing or sewing them on. Preciosa most exclusive product is the MC Chaton Rose VIVA 12®. Known for its brilliance, sparkle and glitter, it features a more intense AB effect and an even greater glue-joint resistance. Preciosa Flat Back Stones are available in a vast array of shapes, sizes, colours and coatings.

APPLICATIONINSTRUCTIONS

Glueing

17

CHOICE OF THE GLUE

The choice of the best glueing system is the first step that ensures a long-lasting application. When selecting the most suitable glue, the following factors have to be considered:

• The cavity type / gap for glueing

• The stone size / glued surface

• The glueing properties and required surface treatment

• The type of the base material

EXAMPLES OF GLUE PRODUCERS

Two-component epoxides Cyanoacrylate Modified silicone Dispersive

Plus 300 Endfest (UHU GmbH)

Cyberbond Apollo 2999 (Cyberbond)

E 6000 (Eclectic product)

DSI glue (DSI visions)

Araldite 2011 (Huntsman Corp.)

Pronto CA 50 gel (3M)

Konishi Ultrabond SU (Konishi Co., Ltd.)

RBC Adhesive 118 (RBC Ind. Inc.)

Loctite 454 gel (Loctite Corp.)

Cemedine Super XG (Cemedine Co., Ltd.)

UHU Sekundenkleber (UHU GmbH)

There are many producers of epoxy glues. The crucial quality of the glue is its curing time of ca. 12 hours at 20 °C. The use of epoxy glues „Rapid“ is not recommended. Never use a quick setting glue which could damage the stone foiling! The use of other unmentioned glues has to be discussed with the Preciosa components sales representative.


MATERIALS FOR GLUEING, TYPES OF GLUE

The following table provides a list of commonly known and readily available glues that are suitable for different applications and materials. It can also serve as a guide to select an optimal glue for the chosen application and base material.

CARE OF TEXTILE MATERIALS WITH NO HOTFIX AND SEW-ON STONES

Textile products with No Hotfix Stones glued or sewed onto them are usually very sensitive to maintenance techniques and require careful handling.

It is therefore strongly recommended that if the need arises, they should only be washed by hand, using lukewarm water with a minimum amount of non-aggressive washing agents (detergents, washing agents designed for use with soft fabrics). Do not tumble dry or wring the washed products. Wrap them in a towel, gently squeeze the water out and then lay them out on an absorbent ground to dry (e.g. like woolen sweaters).

An alternative procedure can be selected only after a positive test result has been achieved with a proof sample.

Material without a flat area

Material under bending stress

Low pressure – the glue does not adhere

Optimal pressure – the glue adheres without spreading out

Pressure too high – the glue spreads out

Hotfix – basic principles

21

Application CuringThe glue should cure for 24 hours to get firm and durable. Do not handle or wash the textile material during this period.

CoolingIt takes about 5 minutes for the glue to cool down after the application. After this time, the stones are fixed to the base material.

CareTextile material with applied stones can be washed at 60 °C, tumble-dried, dry-cleaned and carefully ironed.

5 min

24 hrs

SHAPE OF THE BASE MATERIALBase material without a flat area (rounded, dome-shaped surface) or under bending stress in the application area (e.g. shoes, zippers) is not suitable for applying big stones in particular.

PRESSUREThe application pressure depends on the chosen Hotfix stones, base material and technical equipment (machines etc.). Choosing an appropriate pressure when applying the Hotfix stones is another of the decisive factors for a high-quality bond between the stone and the base material. It is recommended to test the pressure on a material sample.

HOTFIX APPLICATION

Thanks to the unique adhesive, the Hotfix stones can be very gently applied onto most textile

materials. Our Hotfix stones are designed to ensure maximum smoothness and efficiency in

your production process, thus minimizing production costs. Our adhesive layer on the bottom

of the stones enables the use of all state of the art heat-setting devices based on simultaneous

application of heat and pressure as well as ultrasonic devices with application times from 0.3

sec. per one stone.

All application values specified in the table are guidelines only. The optimization of

these for the particular size of the stone, type of textile material and any setting

device requires testing on a sample piece of the carrier material used. Tests should

be always carried out from the start of production. Bond strength of Preciosa stones

on textiles reaches its desired quality in 24 hours from application, therefore it is not

recommended to carry out any testing and washing of applied stones before his time.

HOW TO RECOGNIZE A PROPERLY APPLIED STONE?

A correct combination of application parameters results in a firm bond between the stone and the underlying base material. In this case, a tiny amount of glue is extruded around the stone circumference. The extruded glue does not interfere with the aesthetic aspects of the applied stone as it is not visible by eye, only under a magnifying glass. If thin or soft materials are used the stone is correctly applied when the glue soaks a little through the base material and is visible on the reverse side.

If incorrect parameters are chosen (e.g. too high temperature and pressure or wrong application time) a considerable amount of the glue can melt and soak into the material getting thus away from the stone. The result is a weak bond between the stone and the base material.

If the application temperature or pressure are too low or the application time too short the glue is not sufficiently activated and problems with adhesion occur.

25

CAUSE RECOMMENDATION

1 The application temperature is too low. Increase the temperature by 10 °C (20 °F) at least.

2 The application time is too short. Prolong the application time. In case of a thick or multilayer material apply the heat from the front side through the stone.

3 The pressure is too low. It can occur by application on a thick material. Increase the pressure.

4 Uneven distribution of heat on the heated surface. Check the temperature with a measuring tape or a laser thermometer. If the difference is higher than ca 5 °C (10 °F) repair the heat press.

5 The heat press closes askew. Repair the heat press.

6 The application pad is not suitable. Test different application pads and choose the most suitable one.

7 The application temperature is too high. Lower the temperature by 20 °C (40 °F) at least.

8 The application time is too long. Shorten the application time.

9 The pressure is too high. Decrease the pressure of the heat press.

10 The application pad is too hard. Use a softer application pad.

PROBLEM CAUSE

The stone does not adhere to the base material. 1, 2, 3, 4, 5, 6

The glue spreads around the stone. 7, 8, 9, 10

The stone does not hold on seams or layered materials. 1, 2, 3, 4, 5, 6

POSSIBLE PROBLEMS, THEIR CAUSES AND RECOMMENDATIONS

Th e VIVA12® chaton roses and other fl at-back stones by Preciosa® come complete with a high-quality adhesive layer. When all the application rules are observed, the adhesive is resistant to the following maintenance techniques:

Washing: Before washing textile products with glass stones, turn them inside out.Use a gentle washing cycle (60 °C / 140 °F), and to avoid the stones being damaged, put the products into a soft bag (fl annel).

Ironing: To protect the stones from damage, fi rst cover them with a soft fl annel cloth. Set the iron to a maximum of 150 °C (302 °F). Do not apply heat to the stones for too long as the adhesive might melt.

Drying: Before drying textile products with stones, turn them inside out, and to avoid the stones being damaged, put the products into a soft fl annel bag.In a tumbler dryer, use a low temperature and a gentle drying cycle.

Bleaching: To avoid damage to textile products and to the stones, do not use chlorine bleach.

Cleaning: Textile products with stones can be dry-cleaned, using perchlorethylene. Th is technique requires utmost caution.

Using solvents: Textile products with stones can be dry-cleaned, using hydrocalumites. Th is technique also requires utmost caution – turn the products inside out and put them into a soft fl annel bag.

Professional wet-cleaning: Textile products with stones can be cleanedat a professional cleaner.

While maintaining textile products with Preciosa® stones, it is absolutely necessary to follow the maintenance symbols attached to each garment. In those cases when the values given in the pictograms on the garment exceed the values given in these instructions, it is necessary to adapt them to the values stipulated by Preciosa®.
