SP525 is a low modulus sealant and adhesive formulated
using advanced CPG UK SP polymer technology. It has high
movement capability, excellent primerless adhesion to many
substrates and long-term performance.
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.
