CHEMICAL STABILITY AND REACTIVITY
STABILITY
Stable.
CONDITIONS TO AVOID
High temperatures cause decomposition (see below). DNPH,
commonly used to determine formaldehyde concentrations, will react
with this product resulting in formaldehyde formation. Thus
formaldehyde may be reported as higher than actual and in error.
INCOMPATIBILITY
None known.
HAZARDOUS POLYMERIZATION
None known.
HAZARDOUS DECOMPOSITION
Above 800º C – limestone may decompose to calcium oxide (CaO)
and carbon dioxide (CO2). Above 175º C – polyvinyl acetate may
decompose to H2O, CO2, CO, and acetic acid, could produce vinyl
acetate monomers.

TOXICOLOGICAL INFORMATION
ACUTE EFFECTS: None known.
CHRONIC EFFECTS / CARCINOGENICITY:
There is no vinyl acetate/acetaldehyde/formaldehyde added to this product: Ethylene vinyl acetate polymer is a
common emulsion polymer most familiar as the component of ordinary white glue which exhibits the “sticky”
characteristic. Ethylene vinyl acetate polymer is not classified as a carcinogen by IARC, NTP or ACGIH. Trace
amounts of residual vinyl acetate monomers, acetaldehyde and formaldehyde may be associated with the production
of ethylene vinyl acetate polymer. Any exposure to vinyl acetate monomer, acetaldehyde, or formaldehyde is
expected to remain well below OSHA regulatory and ACGIH recommended limits during normal handling and use of
this product.
Industrial hygiene measurement for exposures to formaldehyde cannot use 2,4-dinitrophenylhydrazine (DNPH) in
sample collection or during analysis due to reaction with an ingredient in this product that will produce formaldehyde.
Sample results will show higher concentrations of formaldehyde than actually exist employing DNPH anywhere in the
analytical method. Previous standard IH sampling measurement using DNPH have shown formaldehyde exposure
concentrations well below 8 hour time weighted average occupational exposure standards including the DNPH error.
Crystalline Silica: Exposures to respirable crystalline silica are not expected during the normal use of this product;
however, actual levels must be determined by workplace hygiene testing. The weight percent of respirable crystalline
