COLOURLOCK Leather Glue (Solvent Free) — Solvent-free adhesive for leather repairs

What does COLOURLOCK Leather Glue Solvent Free do? — The adhesive permanently and flexibly bonds leather, artificial leather, and fabric without a solvent odor, ideal for tears, detachments, and edge repairs in automotive, furniture, and fashion applications.

COLOURLOCK Leather Glue (Solvent Free) is the safe, odor-free, and flexibly curing special adhesive for leather, artificial leather, and textile backing materials. It is perfect for tears, open seams, detached edges, chipped leather pieces, or back-gluing during repairs, without hardening or discoloring the material. The adhesive remains permanently elastic and is therefore ideal for all leather areas that move and are subjected to stress – such as seat bolsters, steering wheels, furniture edges, bags, or shoe areas.

• Flexible leather adhesive without solvents – No odor nuisance, no drying out or hardening of the leather.
• Strong, durable bond – Perfect for tears, detachments, edges, and back-gluing.
• Universally applicable – Works on leather, artificial leather, fabric backings, and many interior surfaces.

Adhesive Technology & Mechanism of Action

Leather Glue Solvent Free is based on modern, water-based polymer dispersions that create a flexible, resilient bond upon drying. Unlike solvent-based contact adhesives, the formula does not attack the leather, does not create hard zones, and remains elastic in the long term. This is crucial for repairs in the automotive and furniture sectors, where leather is constantly moved or stressed. The adhesive layer remains thin, transparent, and stable — ideal as a base for repair materials such as leather patches, binders, fluid leather, or paint.

Preparation, Application & Professional Repair Technique

The affected area should be cleaned and completely dry beforehand. The solvent-free adhesive is applied thinly and precisely and, depending on the type of repair, either bonded immediately or allowed to dry briefly. For tears, a slight back-gluing with a textile backing is recommended before the surface is leveled with a binder or fluid leather. Excess adhesive should be removed immediately, as the adhesive dries transparently but is easier to correct when wet. After complete drying, the area can be color-matched and then sealed.

Results, Areas of Application & Differentiation from Other Adhesives

After curing, a flexible, resilient bond is created that remains stable even under movement. Leather Glue Solvent Free is ideal for car leather seats, furniture, bags, shoe leather, interior trim, and accessories. It is not intended as a contact adhesive for large-area laminations, but for precise repairs, back-gluing, or attaching small pieces of leather. Unlike solvent-based adhesives, it works odor-free, material-friendly, and safely on almost all types of leather.
