Curing agent or Part B of a 2 pack epoxy adhesive. DO NOT use until supplied directions
for use have been read and understood. 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 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.
"epoxy resin amine hardener curing agent aliphatic polyamine polyamide", FR-7020-B
Causes burns.
Risk of serious damage to eyes.
May cause SENSITIZATION by skin contact.
The material can produce chemical burns within the oral cavity and gastrointestinal tract following ingestion. Considered an unlikely route of entry in commercial/industrial environments. Ingestion may result in nausea, abdominal irritation, pain and vomiting. Ingestion of amine epoxy-curing agents (hardeners) may cause severe abdominal pain, nausea, vomiting or diarrhea. The vomitus may contain blood and mucous. If death does not occur within 24 hours there may be an improvement in the patients condition for 2-4 days only to be followed by the sudden onset of abdominal pain, boardlike abdominal rigidity or hypo- tension; this indicates that delayed gastric or esophageal corrosive damage has occurred.
The material can produce chemical burns to the eye following direct contact. Vapors or mists may be extremely irritating. If applied to the eyes, this material causes severe eye damage. 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.
The material can produce chemical burns following direct contactwith the skin. Many amine compounds are sensitizers and some are absorbed through intactskin. Sensitization may result in allergic dermatitis responses includingrash, itching, hives or swelling of extremities. 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. Sensitization reactions may appear suddenly after repeatedsymptom free exposures. Bare unprotected skin should not be exposed to this material. The material may accentuate any pre-existing dermatitis condition. Amine epoxy-curing agents (hardeners) may produce primary skin irritation and sensitization dermatitis in predisposed individuals. Cutaneous reactions include erythema, intolerable itching and severe facial swelling. Blistering, with weeping of serous fluid, and crusting and scaling may also occur. Individuals exhibiting "amine dermatitis" may experience a dramatic reaction upon re-exposure to minute quantities. Highly sensitive persons may even react to cured resins containing trace amounts of unreacted amine hardener. Minute quantities of air-borne amine may precipitate intense dermatological symptoms in sensitive individuals. Prolonged or repeated exposure may produce tissue necrosis.
Inhalation may produce health damage*. If inhaled, this material can irritate the throat andlungs of some persons. Inhalation of vapor may result in nausea, headache. Inhalation of vapor is more likely at higher than normal temperatures. Inhalation of vapor may aggravate a pre-existing respiratory condition such as asthma, bronchitis, emphysema. The material may produce respiratory tract irritation, and result in damage to the lung including reduced lung function. Inhalation of epoxy resin amine hardeners (including polyamines and amine adducts) and may produce bronchospasm and coughing episodes lasting several days after cessation of the exposure. Even faint traces of these vapors may trigger an intense reaction in individuals showing "amine asthma". The literature records several instances of systemic intoxications following the use of amines in epoxy resin systems.
Skin contact with the material is more likely to cause a sensitization reaction in some persons compared to the general population.
Principal routes of exposure are usually by skin contact with the material and inhalation of vapor from the curing material. Prolonged or repeated skin contact may cause drying with cracking,irritation and possible dermatitis following. Epoxy materials may cause allergic and/or contact dermatitis responses, which may occur on exposure or may become apparent only after repeated exposures. Sensitization is possible. Photoallergic dermatitis may result from contact with the material. This type of response can be elicited only in individuals who have been previously allergically sensitized to the chemical agent and appropriate radiation. Photoallergic dermatitis presents, clinically, as an eczematous dermatitis in sun-exposed areas. A few individuals may show allergic/sensitization responses which may be minor to severe. Exposure will aggravate this pre-existing condition and those with sensitization reactions should not be required to work where exposure may occur.
