Superior Stone Products Water-Clear Polyester Stone Adhesive – Quart, Knife Grade
Superior Stone Products Water-Clear Polyester Stone Adhesive – Quart, Knife Grade
The Superior Stone Products Water-Clear Polyester Stone Adhesive in the knife grade is a thick-paste, water-clear polyester stone adhesive supplied in a quart can and cured with 1% to 2% clear liquid hardener (MEKP).
Key Features
- Knife grade viscosity: Superior describes this grade as a thick paste, so it stays where it is placed instead of running.
- Cures with 1% to 2% clear liquid hardener (MEKP).
- Quart can. The flowing grade of the same water-clear resin ships in a quart bottle, item 200-01000-11.
- Water-clear resin, tintable with Superior Coloring Paste.
- One of the two viscosities Superior publishes in this line; the resin chemistry is identical to the flowing grade.
Who Is This For?
Fabricators who want a clear polyester rather than a buff or white filled one, and who are working somewhere the adhesive cannot be allowed to run - an edge, a vertical face, or an open void being packed by hand. A quart can is a bench quantity, not a production pail.
What This Is Not For
Not a setting adhesive: bonding stone or tile to plywood, backer board, concrete or masonry is a different product class, and the Superior Stone Products E-1500-S Tile & Stone Setting Epoxy is the product for that job. Where the adhesive needs to flow into a tight void or a rod slot on its own, use the Superior Stone Products Water-Clear Polyester Stone Adhesive - Quart, Flowing instead of the paste.
Frequently Asked Questions
What hardener does this use?
Superior Water-Clear Polyester adhesive is cured with clear liquid hardener (MEKP) at 1% to 2%.
Is knife grade the same resin as the flowing version?
Yes. Superior publishes Water-Clear Polyester in two viscosities, Flowing (a thick syrup) and Knife Grade (a thick paste), and the resin is the same in both.
Can it be tinted?
Superior Water-Clear Polyester adhesive can be tinted with Superior Coloring Paste.
What container is the knife grade quart supplied in?
The knife grade quart of Superior Water-Clear Polyester, item 200-01010-10, is supplied in a can; the flowing quart is supplied in a bottle.
What is the gel time?
No gel or cure time for Superior Water-Clear Polyester appears in the manufacturer material on file. Set time depends on how much hardener is added and on shop temperature, so use the times printed on the can and the hardener.
