Valmet launches PermaCote carbide coater blades

The challenges in blade coating of paper – quality variations, short blade lifetime and high blade costs – have been overcome by Valmet's new PermaCote eC and nC blades, says the company.


PermaCote eC, made of high quality carbide, is a cost-efficient, long-lasting blade optimized for pre-, back- and middle-coating. It has superior edge wear resistance. According to Valmet, PermaCote eC has significantly reduced the cost/ton related to coater blades on coated board and WFC at several mills.

PermaCote nC is a high quality nanocarbide blade. It has a dense structure optimized for demanding top coating, resulting in extra smoothness. Valmet states that the superior microstructure, improved wear resistance and low tendency for microscale cracking give this blade an exceptionally long lifetime.
