Arroyo WB 1K/2K catalyst is an ML Campbell catalyst designed for water borne systems, so it supports water based finishing workflows where controlled curing is important. The 11 oz size, referenced as ARROYO WB 1K/2K CATALYST-11OZ, provides a defined quantity for finishing runs where repeatable mix ratios matter across multiple jobs. The product is identified as a catalyst in the Solvents, Stains & Finishes category, which places it in the chemical component of a finishing system rather than color or clear coat, helping finishing shops plan material staging around it. ML Campbell branding connects this catalyst with ML Campbell finishing systems, which helps keep chemistry consistent across primers and topcoats in a professional wood finishing process. The Web Description states that Arroyo Catalyst Water Borne must be stirred in and allowed to rest for 5-10 minutes before spraying, so the workflow naturally builds in a short induction period before moving to the spray booth.
The Web Description clearly states that Arroyo Catalyst Water Borne must be stirred in, so the mixing phase becomes a required operation rather than an optional step, supporting consistent distribution of catalyst throughout the water borne coating. That same description specifies a rest period of 5-10 minutes before spraying, which sets a practical induction window the crew can build into their finishing sequence between mixing and loading spray equipment. Treating that 5-10 minute rest as a standard part of the workflow helps maintain a repeatable timeline from mix to spray, which supports predictable behavior of the catalyzed finish on doors, panels, and trim.
This product is categorized under Solvents, Stains & Finishes as a catalyst, so it plays the role of a curing component inside a water borne finishing system rather than a standalone coating. The naming Arroyo WB 1K/2K catalyst connects it directly to Arroyo water borne technology, making it suitable where shops are building 1K or 2K Arroyo water borne schedules on cabinetry, fixtures, or millwork. The 11 oz designation helps finishing departments plan inventory at the container level, matching the number of catalysts on hand to typical batch volumes used in their spray operations. Because ML Campbell is specified as the brand, this catalyst fits best within ML Campbell-based finishing rooms where technicians are already trained around ML Campbell chemistries and process expectations.
The Web Description states that Arroyo Catalyst Water Borne must be stirred in, so technicians work this stirring step into their standard operating procedure before each batch, promoting an even catalyst distribution that supports uniform dry and recoat characteristics. The same description specifies that the catalyzed mix must be allowed to rest for 5-10 minutes before spraying, so crews can structure their workflow to mix, then perform light prep or staging tasks while the mixture equilibrates. Using that 5-10 minute induction consistently helps reduce variation between batches, because each spray pass begins from a catalyzed coating that has had the same rest time. Referencing the product as ARROYO WB 1K/2K CATALYST-11OZ and Manufacturer Part # 000C38277-DP also helps installers and finish shop managers reorder the identical catalyst when they document shop formulas, keeping future runs aligned to the same product identity.
Arroyo WB 1K/2K catalyst is a catalyst in the Solvents, Stains & Finishes category, so it functions as the reactive component within a finishing system rather than as a standalone coating.
Arroyo WB 1K/2K catalyst is described as Arroyo Catalyst Water Borne, indicating it is intended to work within water borne finishing systems where water based chemistry is required.
The Arroyo Catalyst Water Borne must be stirred in, so the mixing step needs to fully blend the catalyst into the finish to support consistent performance during spraying.
The Web Description specifies a 5-10 minutes rest before spraying, giving the catalyzed mix time to equilibrate so spray behavior and film formation stay more consistent between batches.
The catalyst is identified as ARROYO WB 1K/2K CATALYST-11OZ, so each unit provides 11 oz of product for planning batch sizes and inventory.
The Arroyo WB 1K/2K catalyst uses Manufacturer Part # 000C38277-DP, which supports accurate reordering and recordkeeping in professional finishing shops.
Arroyo WB 1K/2K catalyst from ML Campbell provides a defined 11 oz water borne catalyst option identified as ARROYO WB 1K/2K CATALYST-11OZ and 000C38277-DP, so finishing shops can standardize around a specific catalyst identity. The Web Description requirement that Arroyo Catalyst Water Borne must be stirred in and then rest for 5-10 minutes before spraying supports a consistent, repeatable workflow for professional wood finishing. For projects built around Arroyo water borne systems, this catalyst gives installers and finishers a clearly labeled component they can specify in shop formulas and job documentation.
