COLOURLOCK Crosslinker CD – Crosslinker for maximum durability of leather dyes & coatings

What is COLOURLOCK Crosslinker CD used for? – The crosslinker significantly increases the abrasion resistance, water and chemical resistance of COLOURLOCK dyes and coatings, ensuring long-lasting, professional repair and dyeing results.

COLOURLOCK Crosslinker CD is the professional crosslinker for all COLOURLOCK paint and coating systems. It is added to the paints or top coats in small quantities and ensures that the finished surface becomes harder, more resistant and more durable. Especially on heavily used leather and plastic surfaces – such as steering wheels, seat bolsters, furniture edges or grip areas – Crosslinker CD significantly increases durability. Ideal for cars, furniture, bags, interiors and all areas that are subject to high mechanical or chemical stress.

• Increases abrasion & scratch resistance – The paint lasts longer and remains stable, even on heavily used surfaces.
• Optimizes resistance – Improves water, sweat, detergent and alcohol resistance.
• Professional repair quality – Indispensable for durable COLOURLOCK paint systems and top coats.

Crosslinker technology & mechanism of action in the paint film

Crosslinker CD promotes the chemical cross-linking of the binders within the paint or top coat. This cross-linking leads to a more densely cross-linked polymer film that becomes harder, more abrasion-resistant and more resistant to moisture, sweat, cleaners and mechanical stress. The formulation is precisely matched to COLOURLOCK paint systems and activates after the paint film has dried or cured. According to the manufacturer, this creates a professional, robust coating result that remains permanently stable even on heavily used leather components.

Mixing, processing & best practice application

Crosslinker CD is sparingly mixed into the COLOURLOCK paint or top coat. The crosslinker activates the coating, which is why the processed quantity must be used within a certain time window. You can apply the mixture with a sponge, brush or spray gun. Especially for steering wheels, armrests, seat bolsters or bag handles, its use is recommended to ensure maximum durability. After application, the cross-linked layer should completely dry and cure before the surface is stressed. The crosslinker is not intended as a standalone product, but solely as an additive to paints and clear coatings.

Results, areas of application & benefits in detail

After using Crosslinker CD, a highly durable, longer-lasting paint or clear coat is created. The surface appears more stable, less sensitive and withstands everyday use better. Ideal for vehicle detailing, furniture restoration, bag and shoe repairs or commercial use. Crosslinker CD does not replace cleaning, preparation or structural repair – it only optimizes the durability of the final paint layer and is therefore an indispensable step in high-quality leather repairs.
