APLICACIÓN
Preparación de la superficie… Limpie todas las superficies. Las paredes de la junta deben estar en buen estado, limpias, secas, sin escarcha y sin aceite ni grasa. Los residuos de compuesto de curado y todo otro material extraño deben quitarse totalmente. Instale la cinta rompeuniones o KOOL-ROD™ de W. R.MEADOWSpara prevenir la uniónen la base de la junta. Al aplicar sobre el concreto verde, espere 24 horas después de haberquitadolasformas.Elconcretopuedeestarhúmedodurante la aplicación, pero no realice la aplicación cuando haya agua estancada dentro o cerca de las juntas.

SECTION 4: EMERGENCY AND FIRST AID PROCEDURES
EYE CONTACT: Flush eyes with water for fifteen (15) minutes. Seek prompt medical attention. Materials containing
isocyanate may react with moisture of the eye forming a thick material that may be difficult to wash from the eye.
SKIN CONTACT: Remove contaminated clothing. Wash affected area with mild soap and water. If symptoms persist, seek
N/A = Not Applicable medical attention.
INHALATION: If respiratory symptoms develop move victim from exposure source and into fresh air. Treat symptomatically.
If symptoms persist, seek medical attention.
INGESTION: No adverse effects are anticipated by this route of exposure incidental to proper industrial handling.
MOST IMPORTANT SYMPTOMS/EFFECTS, ACUTE AND CHRONIC: See Section Eleven for Symptoms/Effects.
FLASHPOINT: >141 °F
SECTION 5: FIRE AND EXPLOSIVES HAZARDS
EXTINGUISHING MEDIA: Carbon dioxide, dry chemical, or foam. If water is used, it should be applied in large quantity. The
(SARA) and 40 CFR Part 372, chemicals listed on the 313 List (40 CFR Part 373.65) are identified under the heading "SARA 313." reaction between water and hot isocyanate may be vigorous.
CHEMICAL/COMBUSTION HAZARDS: Potentially cyanide containing compounds, carbon monoxide, carbon dioxide, and
incomplete combustion products.
PRECAUTIONS/PERSONAL PROTECTIVE EQUIPMENT: Do not reseal contaminated containers as pressure build up may
rupture them. Responders should utilize full bunker gear and a self-contained breathing apparatus.

SAFETY DATA SHEET
SECTION 6: ACCIDENTAL RELEASE MEASURES
SPILL OR LEAK PROCEDURES: Evacuate personnel as necessary. Absorb with sawdust or other absorbent and shovel into open top containers. Do not make pressure tight. Transport to a well-ventilated area (outdoors) and treat with a neutralizing solution consisting of water and a 3-8% Ammonium Hydroxide solution or a 5-10% sodium carbonate solution. Add about ten parts of neutralizer per part of spill while mixing. Allow to stand forty eight hours allowing evolved carbon dioxide gas to escape.
SECTION 7: HANDLING AND STORAGE
SAFE HANDLING PROCEDURES: Avoid direct contact. Avoid sources of moisture contamination.
SAFE STORAGE: Store in cool, dry location. Keep containers closed when not in use. Protect from freezing. Store at temperatures between 50 and 95 degrees Fahrenheit.

SECTION 11: TOXICOLOGICAL INFORMATION
EYE CONTACT: Direct contact or exposure to vapors may cause mild to moderate eye irritation. Corneal injury is unlikely.
SKIN CONTACT: Direct contact may result in mild to moderate irritation. Prolonged contact may result in skin irritation.
Sensitization reactions are possible.
INHALATION: Exposure may produce irritation to the nose, throat, respiratory tract, and mucous membranes. After repeated
overexposures or exposure to a single large dose, certain individuals may develop isocyanate sensitization (chemical asthma) that will cause them to react to a later exposure to isocyanate at levels below the TLV. Isocyanate sensitization may be temporary or permanent. Once sensitized, an individual may experience these symptoms upon exposure to dust, cold air, or
Chemical or hypersensitive pneumonitis with flu-like symptoms have also been reported. These symptoms can be delayed diagnosed as being sensitized to isocyanate, no further exposure can be permitted. Chronic overexposure to isocyanate has also been reported to cause lung damage (including decreased lung function) which may be permanent. Acute overexposure to isocyanate may also lead to bronchitis, bronchial spasm, and pulmonary edema. These effects are usually reversible.

INGESTION: Single dose oral toxicity is low. Ingestion may cause irritation of the gastrointestinal tract. No hazards are anticipated from ingestion incidental to industrial exposure.
SIGNS AND SYMPTOMS: Symptoms of eye irritation include pain, tearing, redness, and swelling. Symptoms of skin irritation include reddening, swelling, rash, and redness. Symptoms of respiratory irritation include runny nose, sore throat, coughing, chest discomfort, shortness of breath, and reduced lung function. Symptoms of gastrointestinal irritation include sore
throat, abdominal pain, nausea, vomiting, and diarrhea. Lung sensitization results in asthma-like symptoms: chest tightness, shortness of breath, wheezing, and coughing. These symptoms may be immediate or delayed up to several hours.
AGGRAVATED MEDICAL CONDITIONS: Pre-existing skin, eye, and respiratory disorders may be aggravated by product exposure. Persons with asthmatic-type conditions, chronic bronchitis, or other chronic respiratory diseases, recurrent skin eczema, sensitization or allergies should be excluded from working with isocyanates.
