DURO-LAST® SB IV ADHESIVE
Description:
Duro-Last® SB IV Adhesive is a low VOC
solvent-based adhesive used to bond Duro-Last roofing
membrane to a variety of substrates on both horizontal
and vertical surfaces. Acceptable substrates include
plywood, oriented strand board (OSB), structural
concrete, DensDeck® Prime, SECUROCK®
Gypsum-Fiber Roof Board and ACFoam®-IV
polyisocyanurate insulation. Contact the Duro-Last
Engineering Services Department with questions
regarding substrates.
SB IV Adhesive has a VOC content less than 250 g/L
and meets all VOC restrictions and regulations in the
United States.
Material Safety Data Sheet (MSDS):
Product Name: Duro-Last SB IV Adhesive.
Trade Name: Low VOC PVC Bonding Adhesive.
MSDS Number / Product Code: LA432M.
Precautions:
1. Review MSDS for safety information prior to use.
2. Extremely flammable. Do not expose to heat, flame
or sparks. Do not smoke while applying.
3. Use only in well ventilated areas and avoid breathing
vapors.
4. Keep container closed when not in use.
5. When transferring adhesive between containers,
ensure that both containers are grounded.
6. Treat empty containers with caution since they may
contain flammable vapors.
7. Store in the original, unopened, container at
temperatures between 60 °F (16 °C) and 80 °F
(27 °C) and out of direct sunlight.
Installation:
1. Apply to surfaces which are clean, smooth, dry and
free of oil and grease.
2. Only apply adhesive when the ambient temperature
is at least 40 ºF (5 °C) and rising.
3. Stir adhesive vigorously by hand to achieve
homogeneous mixture prior to application. Do not
use electrical equipment or open flame near
adhesive.
4. Thinning the adhesive is not allowed.
5. Using a 3/8 inch (medium) nap solvent resistant
roller apply evenly at a coverage rate of 120 square
feet per gallon per surface to both the backside of
the membrane and to the substrate. This gives a net
coverage rate of 60 square feet per gallon (i.e.
approximately 1.7 gallons per 100 square feet). The
coverage rate will vary depending upon the porosity
of the substrate.
6. Do not apply adhesive to the membrane where
hot-air welding will be performed.
7. Allow adhesive to dry (approximately 5-10 minutes)
until it does not stick or form strings when a dry
finger is pushed into it and removed. The dry time
will vary due to ambient air conditions.
8. Open time prior to mating the membrane to the
surface may extend up to 60 minutes depending on
the ambient air conditions. However, the installer is
urged to apply the membrane to the substrate as
soon as the adhesive is ready.
9. Mate the adhesive coated membrane to the
adhesive coated substrate slowly and evenly to
avoid trapping air and to minimize wrinkles.
10.Immediately broom or roll the membrane into the
adhesive to ensure proper bonding.
