The main components of sponge color paste include organic pigments, inorganic pigments, and other additives. ‌‌

Main components

Organic colorant: made primarily from organic pigments through specific processes. This type of color paste has bright colors, strong coloring power, good weather resistance, and stability. Organic colorants are widely used in various sponge products, especially those that require high color vividness and durability.

Inorganic colorants: mainly using inorganic pigments such as iron oxide, titanium dioxide, etc., which are finely ground and dispersed to produce. This type of color paste has high temperature resistance and chemical stability, and is suitable for sponge products in some special environments. Although there are relatively few color options for inorganic colorants, their excellent performance is irreplaceable in certain specific applications.

Special effect pigments: including fluorescent pigments and pearl pigments. Fluorescent pigments emit bright fluorescence under ultraviolet light, while pearl pigments can impart a sponge pearl like luster. These colorants can create a unique visual effect on the surface of the sponge, enhancing the added value and market competitiveness of the product.

additive

Sponge color paste may also contain other additives such as ethylene oxide (EO), propylene oxide (PO), butylene oxide (BO), and a small amount of catalyst. These additives help improve the performance and stability of colorants.
