FLEX LA432M
LOW VOC ELVALOY ® AND PVC MEMBRANE BONDING ADHESIVE
PRODUCT DESCRIPTION
Flex LA432M is a contact-type bonding adhesive specially designed for bonding Elvaloy® and PVC single
ply roofing membranes and flashings to horizontal and vertical substrates. Flex LA432M has been
engineered to provide ultimate bonding strength and to meet all VOC restrictions and regulations in the
United States.
FEATURES AND BENEFITS
· Low VOC -<250g/L
· Extremely high initial tack
· Fast drying solvent system
· Easy application using roller or brush
· Excellent green strength
· High peel and shear values
· Excellent heat resistance
FLAMMABILITY Red Label – EXTREMELY FLAMMABLE
APPLICATION
1. Use only after careful consideration of the warnings, directions, and first aid instructions given.
2. Apply adhesive when ambient temperature is 40ºF (4.4ºC) and rising.
3. Stir the adhesive vigorously by hand to achieve a homogeneous mixture prior to application. DO
NOT use electrical equipment or open flame near the adhesive.
4. Apply adhesive to the membrane and substrate surfaces which are clean, dry and free of debris.
Apply at the rate of approximately 120 square feet per gallon per surface, sufficient to bond 60
square feet of membrane in place. The coverage rate will vary depending on the porosity of the
substrate surface.
5. Apply adhesive using a 3/8” medium nap solvent resistant roller.
6. Allow adhesive to partially dry to a tacky feel when touched with the back side of a dry finger
before bonding membrane to substrate (approximately 5-10 minutes). Open time prior to mating
membrane to substrate may extend up to 60 minutes.
7. Mate the membrane to the substrate avoiding any air entrapment, and apply pressure by means of
a push broom or roller to assure complete bonding.
NOTE: The shelf life for an unopened container of this adhesive, stored at temperatures between 60ºF
(15.5 ºC) and 80 ºF (26.7 ºC) out of direct sunlight, is 1 year from date of manufacture
