Description
Illbruck SP525 Frame & Facade Sealant & Adhesive 600ml foil
SP525 is a low modulus sealant with high movement capability, excellent primerless adhesion to many substrates and long-term performance. It is also used for the bonding of ME500 & ME501 Intelligent Window Membranes.
USAGE/PURPOSE
SP525 is ideal for sealing joints in façades, rainscreens and curtain walls, perimeter joints around windows, doors and rooflights, and high movement joints (e.g. modular building). It is also used for the bonding of ME500 & ME501 Intelligent Window Membranes. SP525 will enhance the acoustic performance of a joint, providing up to 61 dB sound reduction.
- Meets the requirements of EN ISO 11600 F 25LM
- Formulation based on advanced SP polymer technology
- High movement, rapid curing and extremely low risk of staining*
- Excellent long-term resistance to weathering, ageing and UV
- Low modulus formulation ensures minimum stress at joint faces
- High strength bonding of ME500 & ME501 Intelligent Window Membranes
- Weather and airtight sealing of ME500 & ME501 Intelligent Window Membranes
- Provides up to 61 dB sound reduction in a 10 mm wide joint
