The normal dosages are 5-30 parts of VINTREAT-CAP on the total volume of syntans, depending on the required leather character and substance
The normal dosages are 10 – 40 parts of VINTREAT-SAP on the total volume of syntans, depending on the required leather character and substance.
VINTREAT-SP can be used as a replacement tanning agent is 6 to 18% on the shaved wt. % based on shaved weight, depending on the required leather character and substance.
Vintreat Polymers are available in 20 kg HDPE-lined bags
Vintreat Polymers are used as additives for synthetic tanning agents and can enhance leather quality in the wet-end process. Vintreat Polymers improve leather softness, grain smoothness, and overall brightness and color. Vintreat Polymers can be used with both chrome and vegetable tanned leathers. By using precise dosages, Vintreat Polymers help maintain better, more consistent leather quality while reducing the cost of production.
Absolutely, Vintreat Polymers are highly adaptable and can be blended with any phenol, melamine, dicyandiamide, or naphthalene-based syntans – allowing leather manufacturers to customize the tanning formulation according to the intended leather characteristics. Whether the end result is skin softness, brightness, or filling, Vintreat Polymers help create a better overall product.
Certainly. Vintreat-CAP and SAP are particularly appropriate for wet white leather uses. They aid in producing a fine grain and bright color when dyed in pastel shades. These polymers also aid in better dye penetration, making then excellent for soft, light-colored leather products.
The amount of Vintreat-CAP, SAP, and SP used will vary, depending on the end result and type of leather being treated. In general, Vintreat-CAP works for 5–30 parts, SAP works for 10–40 parts, and SP works for 6–18% AUO based on shaved weight. Tanners are able to achieve the desired combination of softness, fullness, and dye brightness by adjusting their chemical dosages, without losing efficacy.
Vintreat Polymers are a high performance leather chemical that assist with optimizing the tanning process to improve grain, increase fiber strength, and create uniform dye uptake. They are fillers, neutralizers run in the tanning process that result in leather that is light in color, full and soft.
