Bonstone Materials Touchstone Silk Knifegrade Epoxy – 3 Quart Kit
Bonstone Materials Touchstone Silk Knifegrade Epoxy – 3 Quart Kit
The Bonstone Materials Touchstone Silk Knifegrade Epoxy is a translucent white knife-grade epoxy for light-colored marble, granite, quartz and engineered stone, supplied as a three-quart kit of 2 quarts Part A and 1 quart Part B and mixed 2:1 by volume.
Key Features
- Mix ratio is 2:1 by volume - two parts of Part A to one part of Part B.
- Kit is three 1-quart containers: two Part A, one Part B.
- Sets in 2 hours at 70F, deliberately slower than the fast Bonstone adhesives so a long miter can be closed and adjusted.
- Translucent milky white, which is the point of the product - a clear or amber adhesive telegraphs a dark line through light stone.
- Non-sag, non-shrinking, polishable and tintable.
- Published as non-staining with improved UV color stability, both of which are light-stone concerns.
Who Is This For?
Fabricators mitering and laminating white and light-colored material - white marble, light granite, white engineered quartz - where the glue line is visible from across the room and the seam has to disappear rather than merely hold.
What This Is Not For
Dark stone is the wrong application: a translucent white adhesive leaves a visible pale seam on black or dark granite. Use the Bonstone Materials Clear Gel Epoxy for clear knife-grade seams, or the Bonstone Touchstone Glacier Gallon Kit where a clear fast-setting adhesive suits the job better.
