Features & Benefits

• For professional use
• B1 fire class when cured
• Shelf life of 12 months when stored as directed

Ideal for all applications where fire retardant properties are required, for example:

• Installation of door and window frames
• Filling and sealing gaps, joints and cavities
• Filling of penetrations in walls
• Heat insulation of roof construction
• Sealing of cable and pipe penetrations
• Soundproofing and sealing partition walls
• Bonding of insulation materials
• Multi‐Purpose, adhesion and fixation

Technical Data

• Curing System: Moisture cure
• Cure time: 24 hours
• Tack free time (1cm width): 7±3 min (ASTM C1620)
• Cutting Time (1cm width): 30‐45min (ASTM C1620)
• Specific Gravity:
• Hand Held: 22±3 Kg/cm³ (ASTM D1622)
• Gun Grade: 19±3 Kg/cm³ (ASTM D1622)
• Shrinkage: 0%
• Yield: 41L approx.
• Foam colour: Pink
• Thermal Conductivity: 0.036 W/m.k (at 20°C) (DIN 52612)
• Compression Strength: 0.03 MPa (DIN53421)
• Water Absorption: Max 1 vol% (DIN 53428)
• Can Temperature: +5 to +30°C
• Temperature Resistance: ‐40 to +90°C
• Application Temperature: +5 to +30°C

Directions

• Read technical data sheet and safety data sheet (see section above)
• Ensure all surfaces are clean, sound, dry and free from dust, grease or other contaminants
• Application temperature is between +5 °C and +30 °C. Always wear gloves and goggles when applying
• Shake the can well before use
• Moistening the surfaces and the foam improves adhesion and shortens the cure time
• For the Hand Held version, screw the straw adapter onto the valve, turn the can upside down and activate the foam by pressing the valve
• For the Gun Grade version, screw onto an applicator gun, taking care not to overtighten. To apply the foam turn the can upside down and press the trigger, the output of the foam can be regulated with the trigger and controlled with the adjustment screw on the back side of the gun
• Always keep the can upside down during application
• Partially fill the holes and cavities, as post expansion will completely fill the hole
• Fresh foam can be cleaned by AlphaChem Foam Cleaner. Cured foam can be cleaned mechanically
• When finished ensure can is stored upright
• It is the user’s responsibility to dispose of all packaging correctly

Storage and Shelf Life

• Storage: Store in cool, dry conditions between +5°C and +25°C

• Shelf Life: 9 months if stored correctly

Limitations

• Should be stored and transported in a vertical position
• To get the best results, keep at room temperature for at least 12 hours before the application
• Cured foam will discolour if exposed to ultraviolet light. Paint or coat the cured foam for best results in outdoor applications
• Working at lower temperatures will decrease foam yield and cause longer curing time
• It is the user’s responsibility to ensure suitability for use
• Please read the label carefully prior to use as it contains essential health and safety information, it is advised that you should also read the safety data sheet (see section above) prior to use as this contains additional health and safety information to that found on the label
