Slurry additive for rinsing and wet storage:
CHALLENGE 700HT is a synthetic formulation developed for the rinsing and wet storage of lapped/polished parts. CHALLENGE 700HT minimizes scratching from in-process handling; protects parts from staining; and prevents hard-to-clean particles from adhering to the part surface for more effective downstream cleaning. Also recommended for the rinsing/washing of lapping plates, CHALLENGE 700HT removes process debris from both the plate’s surface and grooves, thereby preventing the formation of iron oxide/abrasive particle aggregates that can dislodge and cause scratching. When used for rinsing/washing polishing pads, CHALLENGE 700HT prevents staining; increases pad life by keeping the pore structure open; and reduces the frequency of pad conditioning.
