The washed clothes were stained with. Inhalation: move immediately to fresh air, difficulty in breathing, oxygen supply, respiratory arrest shall immediately give artificial respiration, send to hospital immediately. Ingestion: do not induce vomiting, keep calm Note: according to the specific situation   5 . Fire protection Fire extinguishing materials: water, carbon dioxide, available foam or dry powder fire extinguisher. Fire and explosion hazards: combustion and decomposition products of COx, SiOx and other organic matter may be harmful, fire, closed containers may explode. Special fire fighting procedures: fire and the lifeguard should wear positive pressure air supply device, a comprehensive type of respiratory protective , protective clothing such as a full set of protection device. Set the isolation belt, fire from a safe distance. Flash point: no Ignition temperature: no data . Combustion limit: no data Flammability limit: no data Hazardous characteristics: no Fire fighting procedures and special equipment: according to the local emergency plan, decide whether to evacuate the area or isolation. Container water cooling fire affected. Put out the fire to chemicals, should wear self-contained breathing apparatus and protective clothing . The products of combustion of harmful: carbon dioxide and carbide micro incomplete combustion Prohibition of fire extinguishers use: not determined   6.Leakage emergency treatment Note: personal protective products may cause skin, eye irritation, should avoid direct contact, wash hands, face should diet before. Environmental protection note: prohibit the use of gravel, dirt or other absorbent absorption, into the ditch, river channel. Elimination method: comply with the use of the recommendations in this material safety data sheet listed all the personal protective equipment. If the containment item can be sucked up, should be the appropriate internal container loading. Erase or shovel and loaded into the container, so that recycling or disposal. Proper cleaning up the spill area, because even a small amount of leakage will produce smooth harm. Require the use of steam, solvents or cleaning agents for final cleaning. Appropriate soaked in saturated absorbent or clean handling of goods. Because they can produce self heating. The relevant provisions of the law may be applicable to the goods leakage and release, also applicable to clean up the leak of materials. You need to determine the appropriate laws and regulations.

7931(HT9301MS) MS sealant ,silicon alkyl terminated polyether, sealing of joints, such as weld seam sealing MS sealant is a silicon alkyl terminated polyether as a main component, low viscosity, and general type of one component moisture curable sealant. Curing material combines the advantages of polyurethane and silicone adhesive sealant products, is a new generation of. The operating period is long, low modulus, without bottom coating, curing, paintable with high elasticity, resistance to ultraviolet light and excellent weather ability. Free of solvent, isocyanine free, non silicone, products tasteless environmental protection.   Typical use Applicable to the operating period is long, there is preliminary fixed the sealing of joints, such as weld seam sealing, etc.   Characteristics before curing Typical values range Color white / Black / grey paste The base material chemical composition: Silane modified polyether Density (g/cm3) (GB/T13354-1992)1.47 1.35-1.55 Tack free time (min) 40 10-60 (23℃/50%RH) Pressure flow viscosity(s/10g) 6 5-15 (0.5MPa, 23℃,3mm)   Characteristics after curing Room temperature vulcanized depth (mm/24h) 2.8   2～4 Tensile strength(MPa) 1.5 (GB/T528-1998) ≥0.8 elongation at break (%) 350 (GB/T528-1998) ≥300 Hardness(shore A) 40 (GB/T531-1999) ≥25 Work temperature(℃) -40～90 Short use temperature(℃) 120     Instructions for use Clean :Clean the surface: remove the rust, dust and oil etc... Gluing: The nozzle sleeve cut, take the glue mouth, cut into appropriate slope, using squeeze can glue gun is coated onto the construction site; pneumatic pressure recommended that no more than 0.4MPa sizing. Curing : The parts are arranged in the air sizing, when after the formation of epidermis, from the surface to the interior of a room temperature curing, and 55% relative humidity at 24 hours, the curing depth of 2 ~ 4mm. With the extension of time, the curing depth increases gradually. The 7 day curing depth 6mm. Storage: Unused plastic blocks should be tightened immediately, to seal the tube mouth save. Again, if sealed, a little crust, remove immediately after, does not affect the normal use. In the process of storage, the nozzle may also appear a few crusts, remove after normal use, does not affect the product performance.   The matters needing attention Keep away from children. If you accidentally come in contact with the skin, wipe in the curing a cloth before class, and using alcohol solvent scrubbing. If the case of contact with eyes, rinse immediately with water, and medical treatment.
