PU FOAM SS-45A
PU FOAM SS-45A
Two-component, spray-applied polyurethane foam system
Properties
- Spray applied
- CFC free & HCFC blown
- 45kg density
Description
PUFOAM SS-45A is a two-component, spray-applied polyurethane foam that creates a seamless, monolithic barrier against water vapor and air. PUFOAM SS-45A is an HCFCblown & CFC free, polymeric M.D.I based system for producing rigid urethane foam witha nominal core density of 45 kg/m3 by spray process. The system may be applied to substrates where the surface temperature is of the order of 25 – 30°C. Grades, adjusted in reactivity, are available for both cold and hot condition.
TDS For PUFOAM SS-45A
- Step by Step
Mix ratio
1:1 by volume.
Typical reaction rate and density (laboratory, cup mix) (both components at 20°C)
cream time: 6 – 8 sec.
tack free time: 15 – 25 sec.
free rise density : 32 – 36kg/m3
Reactivity and density may vary depend on ambient temperature and grade
Storage and Handling
Store at room temperature in sealed drums. Moisture will react with this component to produce a surface skin of polymerized material. Protect from moisture and moisture vapour. Close all drums after use. Maximum permissible storage time is 6 months. The ideal storage temperature is between +20ºC and +25ºC. MDI may undergo partial crystallization at temperature below 0ºC. The product can, however, be brought back into the liquid state by placing the container in a heating cabinet and carefully warming the entire contents for a short time to a maximum of 70ºC. Safety goggles, impermeable protective gloves and coveralls should always be worn when handling this product. Contaminated clothing should be removed immediately to prevent further skin contact. Store at room temperature (below 25°C.) in sealed drums. Close all drums after use to prevent loss of blowing agent and absorption of moisture.
