The DS-728A/728B two-component epoxy reaches a tensile bond strength of at least 5.0 MPa after 7 days, with impact strength of at least 80 kJ/m² and Shore D 80 hardness, so the cured joint resists both static load and impact on granite, marble and engineered stone. Shrinkage is held to 1-2% to avoid stress at the bond line. This makes it suitable for structural stone bonding, countertop assembly and natural stone repair where a brittle filler would crack.

No. The formula cures near-colorless with a hue value below 5, so it stays invisible on light marble, white granite and translucent stone where a yellow or grey glue line would show. Mixing ratios are customizable at 2:1, 3:1, 5:1 or 5:2 to match the stone type and working time. The cured resin is also chemical resistant to 15% NaOH solution and is a non-toxic, non-polluting formulation.

Stone adhesive epoxy is supplied in 20 kg, 25 kg, 50 kg, 200 kg and 1,000 kg packs to suit fabrication shops through to large stone processing plants. MOQ for bulk supply is 500 kg with 15-day delivery, ISO 9001 certified. Free samples and the full technical data sheet, including mix ratio and cure schedule, are available before bulk ordering.
