Superior Stone Products White Paste Hardener – 4 oz, BPO
The Superior Stone Products White Paste Hardener is a 4 oz tube of benzoyl peroxide (BPO) paste catalyst for curing Superior's paste-hardener stone adhesives.
Key Features
- Benzoyl peroxide (BPO) white paste hardener, the catalyst Superior specifies for its Gold and Pearl adhesive lines.
- Superior specifies white paste hardener (BPO) at 1% to 3% by weight on its Pearl adhesive page.
- Superior instructs users to use only hardener supplied by Superior.
- 4 oz tube - the larger of the two published sizes, and the shop-bench size against the 1 oz tube.
- Sold separately from the adhesive: Superior's paste-hardener lines ship uncatalyzed.
Who Is This For?
Fabrication shops working through Superior's Gold, Pearl or filled polyester adhesives at a steady rate, where a 4 oz tube is consumed rather than left to sit. It is the size to buy alongside a gallon or larger container of adhesive.
What This Is Not For
White paste hardener does not color the adhesive, so it is the wrong product for anyone running the Gold Evolution system, where the Superior Stone Products Gold Evolution - 4 oz, Colored Hardener, Assorted, 20 per Pack colors and activates the base at the same time. It is also not used with the two-part epoxies, which come with their own Part B - see the Superior Stone Products Epoxy E-1000 & E-1010 - 2-Quart Unit, E-1010, Knife Grade.
