Sarnacol®-2170 (US)
Sarnacol®-2170 (US) is a solvent-based reactivating adhesive used for Sarnafil® or Sikaplan® Adhered roofing systems. It is also used within any Sika approved roofing or waterproofing system for adhering flashings. Sarnacol 2170 is formulated for adhering membranes in a two-step process to clean, dry, surfaces with no slope restrictions.
Usage
Uniquely formulated to be compatible with Sarnafil® and Sikaplan® membranes. AREAS OF APPLICATION Bareback Membrane Substrates- Isocyanurate Organic Facer

Application
Coverage
The coverage rate may vary depending on substrate porosity, ambient temperature, and experience. The typical coverage rate for the following applications are:
- Bareback membrane: 57 - 67 ft2/gal (1.3 - 1.6 m2/L)
- Feltback membrane: 44 - 50 ft2/gal (1.1 - 1.2 m2/L)
SUBSTRATE PREPARATION
All work surfaces should be clean, dry, free of dirt, dust, debris, oils and other contaminants.
MIXING
Mix well before use.
APPLICATION
General Application:
Apply Sarnacol 2170 using solvent-resistant 3/4'' (19 mm) nap paint rollers in a smooth, even coating with no gaps, globs, puddles or similar inconsistencies. Clean any wet adhesive from the seams before welding.
Bareback Membrane Application:
Apply Sarnacol 2170 to the substrate at a rate of 80 - 100 ft2/gal (2 - 2.5 m2/L) and allow to dry. After the substrate adhesive has dried completely, apply Sarnacol 2170 to the back side of the membrane at a rate of 200 ft2/gal (4.9 m2/L) and allow to become tacky (producing strings) when touched with a dry finger. Do not allow the adhesive on the back of the membrane to dry. Roll the tacky coated membrane onto the previously coated dry substrate being careful to avoid wrinkles. Press the bonded sheet firmly in place with a minimum 75 lb (34 kg) steel roller by rolling in two directions. Use a hand roller on vertical flashings.
Feltback Membrane Application:
Apply Sarnacol 2170 to the substrate at a rate of 80 - 100 ft2/gal (2 - 2.5 m2/L) and allow to dry. Apply a second coat of adhesive at a rate of 100 ft2/gal (2.5 m2/L) to the previously coated dried substrate. Do not allow the second coat of adhesive to dry. Unroll the membrane immediately into the second layer of wet adhesive. Press the bonded sheet firmly in place with a minimum 75 lb (34 kg) steel roller by rolling in two directions. Use a hand roller on vertical flashings.
