SIKA Sikaboom 521 Foamfix Low Expansion Gun Grade PU Foam 850ml
Sika Boom®-521 FoamFix is a one-component, gun-applied polyurethane foam with very low expansion and fast curing properties. It is especially suitable for thermal insulation systems and external thermal insulation applications, as well as indoor and outdoor use.
It is designed for bonding insulation boards such as EPS and XPS, plasterboards, wood fibreboards, cork boards and PUR/PIR panels. It provides immediate adhesion, good tensile strength and allows panels to be used within 2 hours after installation.
Its minimal secondary expansion during curing makes it ideal for applications where precision, stability and economical material use are required.
