Section 1 - CHEMICAL PRODUCT AND COMPANY IDENTIFICATION

PRODUCT NAME

HEXAMETHYLENE DIISOCYANATE/ POLYPROPYLENE GLYCOL COPOLYMER

NFPA

PRODUCT USE

Synthetic polymer. CONTAINS free organic isocyanate. Mixing and application requires
special precautions and use of personal protective gear [APMF]. Persons with a history of
asthma or other respiratory problems or are known to be sensitised, should not be engaged
in any work involving the handling of isocyanates. [CCTRADE- Bayer, APMF]. Requires that
the two parts be mixed by hand or mixer before use, in accordance with manufacturers
directions. Mix only as much as is required. Do not return the mixed material to the
original containers.

EMERGENCY OVERVIEW

RISK

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Although ingestion is not thought to produce harmful effects, the material may still be damaging to the health of the individual following ingestion, especially where pre-  existing organ (e.g. liver, kidney) damage is evident. Present definitions of harmful or toxic substances are generally based on doses producing mortality (death) rather than those producing morbidity (disease, ill-health). Gastrointestinal tract discomfort may produce nausea and vomiting. In an occupational setting however, ingestion of insignificant quantities is not thought to be cause for concern.  Considered an unlikely route of entry in commercial/industrial environments.  

EYE

  Although the material is not thought to be an irritant, direct contact with the eye may produce transient discomfort characterized by tearing or conjunctival redness (as with windburn).  

SKIN

  The material is not thought to produce adverse health effects or skin irritation following contact (as classified using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting.  Sensitization reactions may appear suddenly after repeatedsymptom free exposures.  Sensitization may result in allergic dermatitis responses includingrash, itching, hives or swelling of extremities.  Toxic effects may result from skin absorption.  Bare unprotected skin should not be exposed to this material.  

INHALED

  The material is not thought to produce adverse health effects or irritation of the respiratory tract (as classified using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable control measures be used in an occupational setting.  Respiratory sensitization may result in allergic/asthma like responses; from coughing and minor breathing difficulties to bronchitis with wheezing, gasping.  

CHRONIC HEALTH EFFECTS

  There is some evidence that inhaling this product is more likely to cause a sensitization reaction in some persons compared to the general population.  

  Principal routes of exposure are usually by inhalation of vapor/spray mist and skin contact/absorption.  Sensitization may give severe responses to very low levels of exposure, i.e. hypersensitivity. Sensitized persons should not be allowed to work in situations where exposure may occur.  This product contains a polymer with a functional group considered to be of high concern. Isothiocyanates may cause hypersensitivity of the skin and airways. Aromatic isothiocyanates (with benzene rings) may have the potential to cause cancer. Toxicity is lower for larger species because they are less easily absorbed by the body. However even large polymers with more than one high-risk reactive group cannot be classified as a low risk polymer.
