Fluoride water resistant agent for leather - AEM5700

Product introduction

Performance: GOODNICE is a kind of water-soluble fluoride, suitable for all types of leather, can give the garment leather, vamp leather and furniture leather excellent and durable waterproof, anti-oil and anti-staining properties.It can also improve the dynamic water repellency of leather greatly. Whether the same batch or different batches of leather, they could get excellent, uniform features once treated by GOODNICE,besides, their permeability will not change.

Use: GOODNICE is anionic products, you can use it in the retanning stage, such as dyeing or greasing process.

Listing: When the leather is treated with GOODNICE, it can achieve appropriate product quality and performance requirements. 3M can offer the authorization using the "Scotchgard " signs.

The storage temperature of GOODNICE should not exceed 40 °C(104°F).

The freezing point of GOODNICE is at -23°C(-10°F). After freezed before use, the temperature must rise to room temperature, at the same time, you should avoid stirring when thawing.

Shelf life……………… 1 year(from the production date)

Application:

During the practical operation, the best production process should be determined by the type of leather, raw materials and production methods of the tannery.
The two most commonly used technique recommended: bath with the added fat or carry out in the new bath afterwards. You can also combine these two methods to obtain the best performance.

Post-processing method: After the end of all the complex tanning process, you then change new bath with liquid ratio --200-1000%, temperature --60°C, adjust the pH≥4, add GOODNICE weighted 4-8% of shaved leather, and rotate 45 minutes, when GOODNICE is almost absorbed, then add formic acid, adjust the pH to 3.0, at last, control water, wash by conventional methods. This is a standard formula. If productive waterproof leather, you must fix it before or after adding GOODNICE and use it in the proceed of adding fat. In this method, GOODNICE weighted 4-8% of shaved leather is added before, after or simultaneously with fatliquor, not need to change the production process. The advantage of this method is that GOODNICE can penetrate deeply into the leather fibers, and it is an approach of producing waterproof leather and directly producing suede leather.

Notes:

Before use, it is best to dilute GOODNICE with water.

We strongly recommend the use of waterproof fatliquor in order to improve the water resistance of leather,especially the dynamic water resistance.

We also strongly suggest that first check the compatibility of GOODNICE before use, if it is mixed or bathed with other chemicals.

Water hardness affect the stability of the solution of GOODNICE, so we suggest not dilute it with water of more than 20 German hardness.

Dry condition

Suggest heating and drying it in the drying room by conventional methods.
