New TFL surfactant for waterproof leathers
According to specialist chemical company TFL, every tanner involved in the production of waterproof leathers knows how difficult fulfilling technical specifications on wet blues of varying origin and quality can be. From hide to hide and batch to batch, trying to obtain consistently good grain tightness, uniform dyeing, appropriate softness and temper, as well as achieving the required waterproof values can be a real problem for a tannery.
In order to help with this, the company has launched Borron WP, a surfactant with special characteristics for making waterproof leathers. Applied in a separate wash bath before the final chrome fixation, it is particularly effective in the preparation of waterproof leathers where high and uniform dynamic water resistance is required. In addition, the product is suitable for wetting back dried out wet blue and crust materials intended for waterproof leathers.
TFL claims it improves the distribution of silicone-based waterproofing agents and has its own waterproofing capacity. Its dispersing effect improves the penetration of subsequently applied retanning agents and fatliquors without reducing its waterproofness. According to the company, leather produced with the new auxiliary also often has improved tear strength.
Borron WP also has positive effects in wet end applications for standard articles. When it is used as an emulsifier for fatliquors the result is a much better fixation. This feature opens up new possibilities for reducing carbon dioxide levels in the waste water, while supporting savings in chemical costs.
