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.
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. CPG UK provide a service for testing compatibility of our adhesives/sealants with 3rd party materials and would advise that our representative is made aware of this requirement in order to organise appropriate samples and to instigate the required testing (comprehensive testing takes up to 4 weeks). * Whilst CPG UK have not experienced any complaints due to migratory staining, prior tests on natural stone and decorative concrete are recommended. FA870 and FA880 are alternative sealants safe for use on natural stone. When bonding to copper or brass, please consult CPG UK technical services for priming details.
