Conditioner Part Number 159201 Neutralizer Part Number 159202 Final surface preparation is accomplished with M-Prep Conditioner A immediately followed by M-Prep Neutralizer 5. Conditioner A is a mild phosphoric-based acid compound. It acts as a mild etchant and accelerates the cleaning process. Neutralizer 5 is an ammonia-based material. It neutralizes any chemical reaction introduced by the Conditioner A which produces an optimum surface condition for the strain gage adhesive. MSDS - Conditioner A MSDS - Neutralizer 5A |
