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.
Purpose:
SP525 is ideal for sealing joints in facades, and curtain walls, perimeter joints around windows, doors and roof lights, 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.
Contact with bituminous or tar containing surfaces can lead to discolouring. Not suitable for bonding to polyethylene, silicone, butyl rubber, neoprene or EPDM. Not suitable for areas permanently immersed in water.
