What are some of the advantages of using ProSoak, ProSpread and ProDegreaze?
- Elimination of surfactants
- 100% replacement of all NPEO containing chemicals
- No need to add bactericide at soaking
- Reduced chemical costs
- Reduced drawn effect due to better opening of fibers. Hence, higher yield.
- Improved leather quality due to better surface and subsurface cleaning
- Improved hair removal
- Reduced water usage
- Broad pH and temperature range
- Uniform dyeing
- Patch-free surface
- Reduced effluent load
Can I use your products with other chemicals?
Yes, all of our products can be used in the presence of other tannery chemicals.
How do your products work to promote wetting back?
Proviera’s products have hydrotropic properties and can behave like surfactants. Due to the small size of their molecules, they can easily penetrate in the fibril structure of the hides and skins. All these properties result in superior inner hydration, opening up hide fibers and allowing chemicals to go through the entire hide cross section.
What chemicals do your products replace?
Our products do not directly replace other leather tanning products. Rather our products and processes are an efficient alternative system that provides benefits in leather quality, using clean and natural biochemicals that reduce the use of synthetic chemicals or the need of strict controls to avoid leather damages.
For example, at the soaking stage, ProSoak and ProSpread are used in combination. Together, they replace soaking enzymes and surfactants that are used at this stage of the tanning process:
Does the use of your products eliminate or reduce the use of sulfides?
Yes. Sodium sulfide during liming generally can be reduced significantly.
Do your products eliminate the use of enzymes at soaking?
Using ProSoak and ProSpread is as effective as using soaking enzymes, while minimizing the risk of overdosing and avoiding the strict control needed to stop enzymatic activity after processing.
Does the use of ProSoak and ProSpread in the soaking process reduce or eliminate liming chemicals?
No, using ProSoak and ProSpread does not eliminate the use of lime. The advantage of Proviera’s probiotic products is easy unhairing with no visible hair roots or scuds. In addition, the use of ProSoak and ProSpread ensures a better uptake of chemicals as fibers open more compared to the traditional tanning processes.
Will your products work individually?
Our products are designed to work individually. In some stages of processing, they can be combined for better efficiency. For example, when degreasing hides and skins with a very high fat content, it usually is necessary to wash the skins with reduced quantities of an emulsifier after the treatment with ProDegreaze.
What pH range can your products be used in?
Proviera’s products can be applied at any pH, but are more efficient nearer neutral conditions.
What temperature range do ProSoak, ProSpread and ProDegreaze operate in?
All three products perform well within the range of 5°C to 60°C (41°F – 140°F). As a result, the application temperature can be adjusted to improve processing conditions.
On what kinds of hides can I use your products?
Our products can be used on any type of hide and skins — cow (including jumbo bovines), sheep, goat, buff etc.
Do Proviera biochemicals comply with REACH regulations?
Proviera biochemicals are 100% natural, non-hazardous products and are exempt of REACH regulations. Proviera can provide certifications that our products do not contain restricted substances
Any suggestions for wetting back extremely dry wet blue?
In tropical countries, wet blue tends to get too dry and we have seen that best results are obtained by using ProDegreaze at 0.5 % of wet blue weight, in combination with ProSpread at 0.5 %, during the first washing / wetting back.
Which of Proviera products are good for raw hides that contain a great quantity of dung, blood etc.
Normally ProSoak or ProSpread is used at the first stage called “Dirt soak” and both of these Proviera products have shown exceptional cleansing results which are superior to chemicals that are popularly used for this application.
Are Proviera products compatible with bating enzymes?
Yes, ProDegreaze has been used at 0.2 % along with bating enzyme and it has been observed that the compatibility is good and the results are better.
