Farb & Beschichtig

HDK® T40 is a synthetic, hydrophilic, amorphous pyrogenic silica in white colloidal powder form, ideal for various industrial applications such as adhesives, coatings, printing inks, and elastomers. It serves as a thickening agent, reinforcing filler, and free flow additive, offering high purity and performance in organic systems requiring gloss and transparency.

HDK® N20, a pyrogenic silica, is widely used in various industries for its versatility. It is a synthetic, hydrophilic, and amorphous powder produced via flame hydrolysis. With applications in coatings, printing, adhesives, and cosmetics, it acts as a key thickening agent and filler in organic systems like unsaturated polyesters and elastomers. Additionally, it enhances flow in technical powder production. While unsuitable for pharmaceuticals and food, proper dispersion is vital for optimal performance.

HDK H18 is a high-purity, synthetic, hydrophobic, amorphous silica, available as a white colloidal powder. It finds versatile applications across various industries such as adhesives, coatings, sealants, and skincare. Specifically, it serves as a thickening and thixotropic agent in vinylester, epoxy, and polyurethane systems. However, it is not suitable for pharmaceuticals, food, or feed applications. Proper dispersion is essential for achieving optimal performance.

WACKER® TES 40 WN is an ethyl silicate providing approximately 41% of silicon dioxide (silica) upon complete hydrolysis.
