Section 1 - CHEMICAL PRODUCT AND COMPANY IDENTIFICATION

PRODUCT NAME

WATTYL IMPERITE 390 - UV PART A - CLEAR GLOSS

NFPA

PRODUCT USE

A non- yellowing, chemically resistant polyurethane coating. Component A or Base of a 2
pack urethane coating system. 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. The material when ready for use,
i.e. with 2 parts mixed together, CONTAINS free organic isocyanate. Application requires
control measures, special precautions and use of personal protective gear. [APMF].
Application is usually by spray atomisation in a ventilated spray booth, after viscosity
reduction with thinner or may also be applied by brush or hand roller. The use of a
quantity of material in an unventilated or confined space may result in increased exposure
and an irritating atmosphere developing.Before starting consider control of exposure by
mechanical ventilation.

SYNONYMS

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.  Not a likely route of entry into the body in commercial or industrial environments. The liquid may produce considerable gastrointestinal discomfort and be harmful or toxic if swallowed. Ingestion may cause nausea, pain and vomiting. Vomit entering the lungs by aspiration can cause inflammation of the lungs, which can lead to death.  

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 vapour when concentrated has pronounced eye irritation effects and this gives some warning of high vapour concentrations. If eye irritation occurs seek to reduce exposure with available control measures, or evacuate area.  The material may be irritating to the eye, with prolonged contact causing 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.  The material is not thought to be a skin irritant (as classified using animal models). Temporary discomfort, however, may result from prolonged dermal exposures. Good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting.  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.  Respiratory sensitization may result in allergic/asthma like responses; from coughing and minor breathing difficulties to bronchitis with wheezing, gasping.  Inhalation of vapor may aggravate a pre-existing respiratory condition such as asthma, bronchitis, emphysema.  

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

  Principal routes of exposure are usually by inhalation of vapor/spray mist and skin contact with the material.  Prolonged or continuous skin contact with the liquid may cause defatting with drying, cracking, irritation and dermatitis following.  Chronic solvent inhalation exposures may result in nervous system impairment and liver and blood changes. [PATTYS].  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.  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].
