Additional Component Information:

Observe limits for Acetic Acid formed during curing upon exposure to water and humid air. OSHA PEL - TWA 10ppm, ACGIH TLV - TWA 10 ppm, STEL - 15 ppm. Outer compartment contains a flammable hydrocarbon propellant (Propane/Isobutane/n-Butane blend).

HEALTH HAZARD DATA (ACUTE AND CHRONIC)

No injury from silica dust should occur during reasonable use. If use creates respirable particles, some respiratory systems injury may occur. This product, as with any chemical, may enhance allergic conditionsin certain people. No known chronic health effects, but unnecessary exposure to any chemical should be avoided. Cured sealant is nonhazardous.
