Bonder Origin - Acid-Free Primer 10ml

Bonder is the second step in the professional Innerbloom adhesion system. Its role is to create a chemical bridge between the natural nail structure and the technical base applied afterwards.

After preparing the nail plate with Purifier, the nail surface becomes stabilized and ready for the creation of adhesion connections. This is where Bonder comes in.

Its acid-free formula contains specially formulated adhesion monomers that create a microscopic film on the surface of the nail plate. This film acts as an intelligent intermediate layer, compatible with both the natural keratin of the nail and the gel systems applied afterwards.

How it works chemically

The nail plate is made of keratin, a structural protein organized into microscopic layers.

The adhesion monomers in Bonder have the ability to interact with this structure, forming micro-bonds at a molecular level with the keratin surface. At the same time, these monomers remain chemically compatible with the oligomers and monomers in the base applied afterwards.

Thus, Bonder creates a dual compatibility system:

• ▸Connects with the natural nail structure
• ▸Prepares the surface for base anchoring

This mechanism transforms Bonder into a molecular bridge between the nail and the technical system.

Why the formula is acid-free

Acid primers work through an aggressive chemical etching process of the nail plate.
