LEATHER TANIA GRUPPO DAFER SRL

Calcium Formate 98% is used as an animal feed preservative. It acidifies the feed and by doing so, it prevents the growth of microbes and increases the shelf life of the feed. It prevents the growth of bacteria and fungi. It is used as a masking agent in chrome tanning of leather because it enhances the efficiency of leather penetration of the chrome. Calcium Formate is also used as a replacement of formic acid for the pickling process. It is also used as a grout and cement additive. It adds desirable properties to the final products. It helps increase hardness and decrease the setting time. It prevents the corrosion of metal substrates within cement or grout. It very effectively prevents efflorescence. Calcium Formate functions as a fire retardant in drywall. Its mixtures with urea are very effective deicers. These cause less corrosion of steel and cement surfaces.

Keiper CROMA high-performance flat belts are made of fully synthetic polyamide foils, with a one-sided or two-sided adhesion coating of chrome-split leather. Fitted with a polyamide reinforcement. With a one-sided or two-sided coating of chrome-split leather, highly resistant to abrasion and wear. Chrome-split leather is used exclusively as a friction coating on power transmission belts as an alternative to nitrile-butadiene rubber (NBR). CROMA belts with a coating of chrome-split leather are perfect for power transmission applications where the rollers are considerably contaminated by oil and dirt. In view of its slightly porous surface, chrome-split leather is air and humidity permeable and absorbs moisture; thus, it retains friction. However, the coefficient of friction of leather is lower than that for nitrile-butadiene rubber and steadily decreases during operation.
