Superior Stone Products White Paste Hardener – 1 oz, BPO
Superior Stone Products White Paste Hardener – 1 oz, BPO
The Superior Stone Products White Paste Hardener is a 1 oz tube of benzoyl peroxide (BPO) paste catalyst used to cure Superior's stone adhesives, which are supplied uncatalyzed.
Key Features
- Benzoyl peroxide (BPO) paste hardener, published by Superior's distributors as SP-200-45000-00, Superior White Paste Hardener BPO (1 Ounce).
- 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 with its adhesives.
- 1 oz tube, the smaller of the two published sizes; the same hardener is published in 4 oz.
- Called for by Superior's Gold line, which is cured with a BPO hardener rather than a liquid catalyst.
Who Is This For?
Any shop running Superior's paste-hardener adhesives - Gold, Pearl and the filled polyesters - that needs a catalyst on the bench. The 1 oz tube suits occasional repairs and small batches where a 4 oz tube would age before it was used.
What This Is Not For
This is not the catalyst for Superior's Gold Evolution system, where the Superior Stone Products Gold Evolution - 4 oz, Colored Hardener, Assorted, 20 per Pack both colors and activates the base adhesive. It is also not a hardener for the two-part epoxies: the Superior Stone Products E-1500-S Tile & Stone Setting Epoxy and the E-1000 and E-1010 epoxies ship with their own Part B and are mixed to a published ratio instead.
