KiurLab Pro Leather Crosslinker CX is a professional crosslinker (hardener) added to leather paint and Top Coat within the KiurLab PRO LEATHER system to maximise the durability of the coating. The product forms strong chemical bonds within the coating structure, delivering a measurably increased resistance to abrasion, moisture, and intensive daily use.

The formula is isocyanate-free, making it more comfortable to work with compared to conventional hardeners – without compromising on performance. Crosslinker CX maintains the elasticity of the coating and is suitable for everything from soft nappa leather to hard plastic trim.

The product is developed for professional use in detailing and leather restoration. See more KiurLab products for car care in our range.

What is Crosslinker CX and why choose it?

Crosslinker CX is a crosslinking agent that acts as a hardener within the KiurLab PRO LEATHER system. When added to leather paint or Top Coat, it activates chemical reactions that reinforce the internal structure of the coating, providing substantially improved resistance to abrasion, perspiration, and moisture – properties that are critical on surfaces such as steering wheels, door panels, and other high-wear details.

Unlike conventional isocyanate-based hardeners, Crosslinker CX offers a more modern formula that is more comfortable to work with, whilst delivering a measurable difference in coating longevity. The dosage can be precisely adjusted according to surface type and level of wear, giving the detailer full control over the final result.

Where is this product suitable?

• Automotive interiors with intensive wear – steering wheels, door panels, centre console
• Soft nappa leather in passenger cars and luxury vehicles
• Embossed leather types such as Dakota and Valcona
• Eco-leather and vegan leather, both soft and hard surfaces
• Plastic trim in vehicle interiors
• Leather goods in natural leather

Frequently Asked Questions (FAQ)

Does KiurLab Pro Leather Crosslinker CX work on all types of automotive leather?

Yes, KiurLab Pro Leather Crosslinker CX is developed to work across a wide range of surface types within the KiurLab PRO LEATHER system. The dosage is adjusted according to surface type: soft nappa leather requires a lower addition (1–4 % depending on whether leather paint or Top Coat is used), whilst embossed leather types such as Dakota and Valcona, eco-leather, vegan leather, and plastic trim require a higher dosage of up to 8 % for Top Coat on plastic. It is important to select the correct dosage in order to achieve the best possible durability without negatively affecting the elasticity of the coating.

What volume does KiurLab Pro Leather Crosslinker CX come in and how long does the mixed product remain usable?

KiurLab Pro Leather Crosslinker CX is supplied in a 50 ml container. Once Crosslinker CX has been mixed with leather paint or Top Coat, the mixture must be used within 4 hours – after this point the curing process begins and the product can no longer be applied correctly. KiurLab therefore recommends preparing only the quantity of mixture actually required for the job at hand, in order to avoid waste and ensure an optimum result.

What sets KiurLab Pro Leather Crosslinker CX apart from other hardeners for leather treatment?

KiurLab Pro Leather Crosslinker CX differs from many conventional hardeners through its isocyanate-free formula, which provides a more comfortable working environment without compromising on effectiveness. The product is specifically developed for the KiurLab PRO LEATHER system and works with both leather paint and Top Coat, delivering a cohesive and reinforced coating structure. Crosslinker CX also maintains the elasticity of the coating – an important property on flexible surfaces such as steering wheels and door panels – unlike hardeners that can render the coating brittle. We offer Crosslinker CX as part of a complete range of KiurLab PRO LEATHER products for professional use.
