Replacing Grit Blasting with Silane
Q.This question is in regards to an article in Products Finishing's October 2004 issue addressing powder coating 304 stainless. We are a batch shop in Oregon. We coat a large quantity of 304-stainless tubing. We currently grit blast for “tooth.” Blasting is very labor intensive. I noticed the mention of Silane in the clinic. Is it possible to use Silane as a stand in place adhesion promoter to replace grit blasting. If so, who would you recommend as a material provider. N. H.
A. Yes, Silane does promote powder coating adhesion on a variety of products such as glass and stainless steel. Silane is applied in liquid form and is sold under a variety of product names from most all pretreatment chemical suppliers.
How can you calculate the cost of powder coating a component if you only know its surface area? Powder coating expert Rodger Talbert has the answer.

Masking is employed in most any metal finishing operation where only a specifically defined area of the surface of a part must be exposed to a process. Conversely, masking may be employed on a surface where treatment is either not required or must be avoided. This article covers the many aspects of masking for metal finishing, including applications, methods and the various types of masking employed.
