Sealers

ALUMAL SEAL MTS 909

ALUMAL SEAL MTS 909

ALUMAL SEAL MTS 909 is a weakly acidic, anionic surfactant-free nickel acetate seal designed for medium temperature sealing of anodized aluminum. It is one of the most versatile medium temperature sealers on the market and can be applied over both clear and colored (dyed or electro-colored) aluminum surfaces.

Operational advantage

ALUMAL SEAL MTS 909 is offered as a single component liquid additive for ease of make-up and replenishment. 

Cost effectiveness

Works at lower temperature range (82 - 85°C) versus conventional hot sealing, providing remarkable energy savings. 

Improved sealing quality

ALUMAL SEAL MTS 909 prevents the bleeding of organic dyes on colored parts.
