CHEMTAN® 220 A sequestering agent based on EDTA with low NTA content. Used to tie up iron. Typically iron is found in hard water, and this product prevents discoloration in the leather caused from the reaction between iron and extracts used in the retannage or main tan. Produces cleaner, and brighter colors. powder 99% 11.0
CHEMTAN® 440A Hydrophobic silicone defoamer. Defoaming of floats in water resistant retans. Reduction of foam leads to improved chemical distribution and exhaustion resulting in more consistent leather character and performance. The product will not negatively affect water resistance. liquid 100%
CHEMTAN® CR-1 Removes residual calcium on the bluestock surface, and can be used for both waterproof and non waterproof leathers. The following chemical additions in the retan, coloring, and fatliquoring are found to be less likely to precipitate on the surface which typically has a negative influence highlighting defects and poor color uniformity. When applied at a 1- 2% level as a pre wash cleaner, brighter, and more uniform coloring is obtained. Dye levelness, color uniformity, and dye penetration are markedly improved. liquid 39% 10.5
CHEMTAN® E-69 A syntan dispersion for retanning to help produce soft milled leathers for increased cutting yields. This product masks imperfections, and fills veins. Significant plumping occurs in the retanning unlike normal syntans. This is a heat activated product@70C for 30 minutes before drum washing. liquid 60% anionic
CHEMTAN® M-55 A brominated flame retardant used to make leather flame resistant. Use of this product will result in leather which will not support combustion. This product has a minimal effect on temper and water resistance. Can be used in the drum, or sprayed together with finish mixes, or added to the dry mill as a spray mist. liquid 44% 9.5~10.0 anionic
CHEMTAN® R-117 A unique, spherical shaped polymer, which povides filling, and whitening properties in drum application. Improves color brightness, and color clarity for pastels and white leathers. Milky white appearance, anionic charge, concentration 30% activity, and the pH is 8.3 liquid 30% 8.3 anionic
