Koch-Chemie × COLOURLOCK COLOURLOCK "Leather Shield" Leather Care Product for New Leather to Protect Against Wear 1000ml

Maximum Abrasion Protection for New Leather with COLOURLOCK × Koch-Chemie Leather Shield

How does COLOURLOCK × Koch-Chemie Leather Shield protect new leather? — Through an invisible anti-friction polymer, Leather Shield forms a fine protective film on the leather, reducing abrasion on the steering wheel, entry areas, and seat bolsters, and keeping new leather uniformly matte and clean for longer.

COLOURLOCK × Koch-Chemie Leather Shield is your professional care product if you want to protect factory-fresh or like-new smooth leather long-term from abrasion, creasing, shiny spots, and color loss. The formula comes from COLOURLOCK leather technology, combined with Koch-Chemie's system chemistry – perfect for new cars, lease returns, and detailed interior preparation. Leather Shield prevents typical early aging in heavily used areas and creates a pleasant, matte surface with a natural feel.

• Long-term Anti-friction Protection – The polymer film minimizes mechanical wear on side bolsters, steering wheel, and entry areas. The leather remains dimensionally and color stable for longer because micro-abrasion is significantly reduced.
• Gloss-inhibiting Effect – New leather, in particular, quickly develops an unwanted shine with use. Leather Shield maintains the matte appearance and prevents greasy spots, without sealing or sticking to the surface.
• Cleanliness & Easy Care – Due to the altered surface energy, dirt adheres less. Subsequent interior cleaning is faster and gentler, especially in combination with a mild leather cleaner.

New Leather Protection Technology & Surface Behavior

The heart of Leather Shield is a finely cross-linked polymer that selectively adheres to pigmented smooth leather surfaces without impairing their breathability or haptics. In practice, this means: Your leather continues to behave naturally, feels soft, but shows significantly less friction gloss and micro-wear. Especially with modern automotive leathers with a PU topcoat, daily entry and exit, clothing edges, rivets, or belt ends act like sandpaper — the polymer film acts here as a sacrificial protective layer. According to manufacturer data, the formulation is designed so that it neither builds up nor cracks, but wears evenly and can be renewed if necessary. You avoid typical mistakes like generous "massaging in": Leather Shield works best when applied thinly, evenly, and completely dried.

Leather Preparation & Optimal Application for Detailing

For maximum performance of Leather Shield, thorough preparation is crucial. First, clean new or like-new leather with a mild leather cleaner to remove manufacturing residues, light body oils, and micro-dirt. The product is applied with a soft applicator in straight, overlapping strokes until a homogeneous film is formed. After a short drying time, the leather dries to a silky matte finish; typical re-polishing is not necessary because the product does not form wax-based residues. Especially in detail areas – steering wheel, console leather, side bolsters – precise work pays off. In combination with regular mild cleaning, the protective effect remains stable. For heavily used vehicles such as company cars or daily drivers, a quarterly refresh is recommended, as these areas experience higher mechanical stress.

Results, Durability & Typical Application Areas

After applying Leather Shield, the leather's look remains original matte and free from greasy shine, which quickly becomes visible, especially in dark interiors. Durability naturally depends on use and material, as the product is mechanically worn away as a protective layer. In everyday vehicles, the benefits are most apparent: uniform wear, less creasing, and significantly later appearance of shine on side bolsters and steering wheels. For leased vehicles, Leather Shield is almost mandatory, as it slows down visible aging and maintains the interior's appearance until return. The product also convinces in professional detailing as part of a systematic leather care process, as it is neither silicone-based nor over-conditioning and harmonizes perfectly with mild cleaners and subsequent conditioner care.

Frequently Asked Questions about COLOURLOCK × Koch-Chemie Leather Shield

Can I also use Leather Shield on older leather?

Yes, but older surfaces should be thoroughly cleaned beforehand and lightly refreshed if necessary. For severely dried-out leather, a conditioner also helps. However, the product works best on like-new surfaces.

How often should I renew Leather Shield?

With normal use, approximately every three to five months. Heavily used areas such as entry bolsters or steering wheels benefit from more frequent refreshing.

Does the product create a greasy shine?

No. Leather Shield is explicitly mattifying and preserves the natural surface without building up or shining.

Is the product suitable for perforated seats?

Yes, as long as it is applied thinly and not "massaged" into the perforation. A light, even application is sufficient.

Can I use a conditioner after Leather Shield?

Yes. First clean, then Leather Shield for friction protection, then conditioner for suppleness. This way you get protection and care in a coordinated system.
