SDP1222 building wall insulation system blend polyol is a kind of B2 grade spray rigid PU foam blend polyol, specially used for the insulation of building external wall. It used together with isocyanate(PM-200) to make rigid PU foam through PU spray machine. The foam produced has the characteristics as following:

The thickness of one gun spray foam should not exceed 35 mm. If over 35mm, which may cause foam charring or spontaneous combustion and poor foam performance.
It is suggested that spray next layer of the foam after the internal temperature of last spray foam blow 25ºC. And the maximum thickness spray during 24h period is 203mm(8inches).
Like most of foam product, foam made by SDP1222 is combustible. An thermal barrier must be installed in accordance with approved construction standards.
The service temperature of the foam with SDP1222 is between -60~80ºC.

The blend polyol should be stored in the sealed container to avoid the absorption of water vapor. During the transportation, it should avoid serious shake and strong sunlight. It should be stored in ventilated place, avoiding light, water and fire. Recommended storage temperature is 15~25ºC.
Direct contact with SDP1222 type blend polyol can lead to moderate eye irritation and mild skin irritation, which can cause skin allergies. Repeated inhalation of high concentration of volatile gas will cause respiratory allergy, and should be treated immediately. Anti- inflammatory and anti-allergic treatment measures should be taken.
Please be careful in the operation to prevent contact with the skin and splash into the eye, please wear the necessary protective equipment (gloves, protective goggles, working clothes, etc.).
Once splashed on the skin or the eye, rinse with water immediately for at least 15 minutes, and the skin is washed with soapy water. Please seek medical treatment immediately after swallowed.
