Environmental Resistance
UPILEX-S features low water absorption and hygroscopic expansion. Another advantage inherent in UPILEX-S is its low absorption . desorption speeds and superior weather resistance.

1.Statement Content
The statement content is based on materials, data and information currently available and no guarantee id made with regard to content, physical properties or hazards and harmful effects. Furthermore, as handling precautions relate to normal handling, in cases of special handling, safety measures appropriate to the application and its method should be taken.
2.Handling Precautions
‧When handling UPILEX-S at high temperatures attention should be paid to ventilation. This is because DMAC, of which UPILEX-S contains traces, produces carbon monoxide at generates pyrolytic products.
Ventilation should be adequate to ensure that concentrations of DMAC and carbon monoxide are kept to sage levels ( 10ppm and 100ppm ). In addition, breathing safety equipment, such as oranic gasmasks, should be used to prevent the inhalation of fumes.
‧Ad data relating to health and the natural environmnent are incomplete, the greatest caution should be exercised when handling UPILEX-S.
‧When disposing of UPILEX-S, the material should be burned in an appropriate incineralor as there is concern about cnvironmnental pollution.
‧Please read the material safety data sheet ( MSDS ) before use. If you have not received a MSDS, please reuest one from the company.
3.Fire Measures
Fires should be extinguished with powder, carbon dioxide, foam fire extinguishers or water sprays.
4.Emergency Measures
‧If UPILEX-S enters the eye, particles should be flushed out thoroughly and immediately with clean water. If the eye becomes bloodshot or exhibits any other abnormality, medical assistance should be sought.
‧In case of contact with the skin, the affected area should be washed with soap and large quantities of water. If irritation persists, medical advice should be sought.
‧If swalloed, induce vomiting, wash the mouth and seek medical attention.
