DACROMET®
DACROMET®, is the leading inorganic coating commonly specified in the wind turbine, heavy truck, marine, agricultural, construction equipment and aerospace industries. A water-based, VOC-compliant coating, DACROMET® is comprised mainly of overlapping zinc and aluminum flake in an inorganic binder.

SHOT PEENING
Shot peening is a cold working process used to produce a compressive residual stress layer and modify mechanical properties of metals and composites. It entails impacting a surface with shot with force sufficient to create plastic deformation. Shot peening is often called for in aircraft repairs to relieve tensile stresses built up in the grinding process and replace them with beneficial compressive stresses.
