Polysulfide-based joint sealant
Description
ABAK FlexSeal PS is a two-part, low-modulus, chemically curing polysulfide joint sealant specially developed for dynamic joints. It consists of a liquid polysulfide polymer that, when mixed with the hardener, cures to form a durable rubber-like seal. ABAK FlexSeal PS is available in both gun and pouring grades.
The product exhibits exceptional UV resistance and offers flexibility, tear resistance, and non-staining properties. It adheres well to various building materials including cementitious substrates, aluminium, glass, wood, and mild steel. ABAK FlexSeal PS demonstrates excellent recovery characteristics even after prolonged compression or elongation, and it shows outstanding resistance to chemicals, weather conditions, aging, and shrinkage.
