Vlotho CROSSLINKER Polyurethane Coating Crosslinker

VLOTHO Cross Linker — Professional crosslinker for water-based polyurethane and acrylic coatings. Used as an additive to paints and topcoats to enhance their performance properties. After adding to the material, the Crosslinker forms additional chemical bonds between polymer molecules, making the coating significantly more durable and resistant to abrasion, water, sweat, oils, and other external factors.

Crosslinker does not affect the color, transparency, or gloss level of the coating, preserving the original appearance of the material. Used in professional dyeing, repair, and restoration of leather goods where maximum durability and coating resistance are required.

Advantages

• Significantly increases the wear resistance of the coating;

• Improves color fastness;

• Enhances water resistance;

• Reduces the risk of staining clothing during product use;

• Increases resistance to sweat, fats, and oils;

• Improves interlayer adhesion of the paint coating;

• Does not alter the transparency or gloss level of the topcoat;

• Compatible with water-based polyurethane and acrylic materials.

Usage Area

Crosslinker is used together with:

• Polyurethane paints;

• Acrylic paints;

• Polyurethane topcoats;

• Water-based protective varnishes;

• Coatings for leather, footwear, and leather goods.

Recommended for professional use in repair, restoration, and manufacturing of natural leather products.

How to Use

1. Add Crosslinker to the ready-to-apply paint or coating material.

2. Recommended dosage — 1–3% by weight of the finished mixture according to the paint manufacturer's recommendations.

3. Stir thoroughly until a uniform mixture is obtained.

4. After adding the crosslinker, the working mixture should be used within 1–2 days.

5. After finishing work, clean tools with alcohol or a water-alcohol mixture.
