WEVO – HARDENER 300

Take the person into the fresh air and keep him warm, let him rest

Symptoms: difficulty in breathing

In the event of contact with the skin, preferably wash with a cleanser based on polyethylene glycol or with plenty of warm water and soap.

Symptoms: skin reaction

Hold the eyes open and rinse with preferably lukewarm water for a sufficiently long period of time (at least 10 minutes). Contact an ophthalmologist.

DO NOT induce the patient to vomit

Carbon dioxide (CO2), Foam, extinguishing powder, in cases of larger fires, water spray should be used.

High volume water jet

Burning releases carbon monoxide, carbon dioxide, oxides of nitrogen, isocyanate vapors and traces of hydrogen cyanide. In the event of fire and/or explosion do not breathe fumes. Fire in vicinity poses risk of pressure build-up and rupture.

Containers at risk from fire should be cooled with water and, if possible, removed from the danger area.

Keep unauthorized persons away.

Do not flush into surface water or sanitary sewer system.

After approx. one hour transfer to waste container and do not seal (evolution of CO2!). Keep damp in a safe ventilated area for several days.

Provide sufficient air exchange and/or exhaust in work rooms. In all workplaces or parts of the plant where high concentrations of isocyanate aerosols and/or vapors may be generated (e.g. during pressure release, mold venting or when cleaning mixing heads with an air blast), appropriately located exhaust ventilation must be provided in order to prevent occupational exposure limits from being exceeded. The air should be drawn away from the personnel handling the product. The efficiency of the exhaust equipment should be periodically checked. The threshold limit values noted in Chapter 8 must be monitored. The personal protective measures described in Chapter 8 must be observed. Contact with skin and eyes and inhalation of vapors must be avoided under all circumstances.

Keep container tightly closed and dry. Prevent cooling below 10°C and heating above 40°C. Storage best at +15°C to +25°C.

Keep away from foodstuffs, drinks and tobacco. Wash hands before breaks and at the end of workday. Keep working clothes separately. Take off all contaminated clothing immediately. Decontaminate, destroy and dispose of soiled protective clothing (see Section 13).

Respiratory protection required in insufficiently ventilated working areas.

Suitable materials for safety gloves; EN 374-3: Polychloroprene - CR: thickness >=0,50 mm; breakthrough time >= 480 min. Nitrile rubber- NBR: thickness >=0,35 mm; breakthrough time >= 480 min. Butyl rubber - IIR: thickness >=0,50 mm; breakthrough time >= 480 min. Fluorinated rubber - FKM: thickness >=0,40 mm; breakthrough time >= 480 min. Recommendation: contaminated gloves should be disposed of.

Wear eye/face protection.

Respiratory protection required in insufficiently ventilated working areas and during spraying. An air-fed mask, or for short periods of work, a combination o f charcoal filter and particulate filter is recommended.

Wear suitable protective clothing.

Polymerises at about 200 °C with evolution of CO2.

Exothermic reaction with amines and alcohols; reacts with water forming CO2; in closed containers, risk of bursting owing to increase of pressure.

amines and alcohols

No hazardous decomposition products when stored and handled correctly.

After final product withdrawal, all residues must be removed from containers (drip-free, powderfree or paste-free). Once the product residues adhering to the walls of the containers have been rendered harmless, the product and hazard labels must be invalidated.
