Before the introduction of walnut shell blasting, coatings were normally stripped down to bare metal and required a replacement of the undercoat, vinyl coat, and topcoat. This coating removal blasting technology also enables selective coating removal and saves significant time and money.
At present, walnut shell blasting is being used safely and effectively across a range of industries and applications.
The media is also durable, re-usable and biodegradable and reduces the cycle time of finishing operations; it preserves microfinishes and replaces sand to prevent silicosis. Selective coatings removal is also possible with walnut shell sandblasting.
Specifically intended for use in dry air blasting applications, walnut shells are a lightweight, angular media that will effectively remove topcoats while leaving undercoating intact.
Walnut shell does not contain heavy metals or free silica. Walnut shell is resistant to rupture and deformation, allowing for it to be recycled up to four times. Specialty petrochemical or offshore applications where a minimal sparking, non-ferrous abrasive is required.
