Sealer 300 W 2.0

The latest generation of inorganic sealer

Sealer 300 W 2.0 offers the outstanding features of Atotech’s patented inorganic Sealer 300 W family. Additionally Sealer 300 W 2.0 shows reduced residues for less afterwork efforts and a more homogeneous appearance.

Sealer 300 W products are used around the world whenever outstanding performance is required. The patented inorganic reactive Sealer 300 W family provides highest corrosion protection, even after assembling.

Rather than simply building a film over the passivate layer, this technology reacts with the passivate to form a durable bond. This unique trait has proven to have the best performance in outdoor corrosion conditions.

During drying, the sealer reacts with the underlying passivate to form a unique crack-free bond. This results in continuously high long-term corrosion protection without aging. Excellent performance at corrosion protection was achieved in neutral salt spray tests and corroborated by results in cyclic corrosion and outdoor exposure tests, where it outperforms conventional sealer technologies.

The sealer is purely inorganic to be compatible with brake fluid. Different lubricated sealer versions are available to cover the whole range of friction requirements for the automotive fastener industry.

What inspires us

Why we developed Sealer 300 W 2.0

Your challenge

Customers are looking for solutions which offer better appearance in terms of residues and drop marks as well as a homogeneous distribution of layers.

The right product should decrease effort required to clean and brush finished calipers.

It should be heat-treatable to ensure that hydrogen de-embrittlement baking can be done at the end of the whole plating process. It should also be capable of resisting the effects of aggressive brake fluid and wheel cleaner.

Our solution

Sealer 300 W 2.0 offers the same features as the Sealer 300 W family plus reduced residues for less afterwork effort and a more homogeneous appearance.

The patented inorganic reactive Sealer 300 W family provides the highest corrosion protection, even after assembly.

The sealer is purely inorganic to be compatible with brake fluid.
