Section 1 - CHEMICAL PRODUCT AND COMPANY IDENTIFICATION

PRODUCT NAME

WATTYL SIGMAWELD MC (PART A)

NFPA

PRODUCT USE

Part A or hardener of a two pack moisture curing inorganic zinc ethyl silicate
prefabrication primer. 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. Application is usually by spray
atomisation. The use of a quantity of material in an unventilated or confined space may
result in increased exposure and an irritating atmosphere developing.

SYNONYMS

"two pack zinc silicate ethylsilicate coating inorganic zinc dust paint"

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.  Ingestion may result in nausea, pain, vomiting. Vomit entering the lungs by aspiration may cause potentially lethal chemical pneumonitis.  

EYE

  This material can cause eye irritation and damage in some persons.  The liquid produces a high level of eye discomfort and is capable of causing pain and severe conjunctivitis. Corneal injury may develop, with possible permanent impairment of vision, if not promptly and adequately treated.  The material may produce severe irritation to the eye causing pronounced inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis.  

SKIN

  Skin contact with the material may damage the health of the individual; systemic effects may result following absorption.  This material can cause inflammation of the skin oncontact in some persons.  Toxic effects may result from skin absorption.  Bare unprotected skin should not be exposed to this material.  The material may accentuate any pre-existing dermatitis condition.  The material may cause skin irritation after prolonged or repeated exposure and may produce on contact skin redness, swelling, the production of vesicles, scaling and thickening of the skin.  

INHALED

  If inhaled, this material can irritate the throat andlungs of some persons.  Inhalation hazard is increased at higher temperatures.  Inhalation of high concentrations of gas/vapor causes lung irritation with coughing and nausea, central nervous depression with headache and dizziness, slowing of reflexes, fatigue and inco-ordination.  If exposure to highly concentrated solvent atmosphere is prolonged this may lead to narcosis, unconsciousness, even coma and possible death.  

CHRONIC HEALTH EFFECTS

  Ample evidence exists, from results in experimentation, that developmental disorders are directly caused by human exposure to the material.  

  Refer also to protective measures for the other component used with the product. Read both MSDS before using; store and attach MSDS together.  Principal routes of exposure are usually by inhalation of vapor/spray mist and skin contact with the material.  Chronic solvent inhalation exposures may result in nervous system impairment and liver and blood changes. [PATTYS].  Prolonged or continuous skin contact with the liquid may cause defatting with drying, cracking, irritation and dermatitis following.
