Description
A high density polyurethane foam saturated with acrylic which, when compressed provides a seal against dirt, dust, dampness, vibration, drafts and water. Biyseal acrylic retains its elasticity indefinitely, expanding and contracting with the joint movement.
PERFORMANCE DETAILS:
COMPRESSION: As compression increase Biyseal Acrylic becomes more impermeable. As a guide, compression of –
- 25% is sufficient for air, dust and vibration
- 50% is sufficient for moisture
- 75% is sufficient for heavy rain and water
RECOVERY: Biyseal acrylic can be compressed to 10% of its original width and will recover to more than 90% after any number of cycles of compression and expansion.
COMPATIBILITY: Biyseal acrylic is compatible with water-based paints and mastics.
SERVICE TEMP: Biyseal acrylic can be used in a wide temperature range –10 degrees C to +70 degrees C
FIRE RESISTANCE: Compressed Biyseal acrylic is self-extinguishing when compressed between non-inflammable materials.
USES:
- Biyseal acrylic provides an inexpensive and effective seal in many applications

DIRECTIONS FOR USE:
- Store away from dust and direct sunlight
- When unpacking, allow material to lie for a period for maximum recovery
- Surfaces to which Biyseal acrylic is applied should be clean and free of grease and oils
- Ensure that dimension of Biyseal acrylic is correct for the joint size and compression required
- Compress product by hand or roller immediately before placing
- Biyseal Acrylic will expand quickly to fill and seal the opening
- When joining strips splice ends with wet knife at an angle to properly join
