Frequently asked questions about Parabond MS polymer and hybrid sealants
What is an MS polymer or hybrid sealant?
MS polymer sealants – also known as hybrid sealants – are modern adhesives and sealing products that combine the best properties of silicone and PU sealants.
They are solvent-free, low-odour, UV- and weather-resistant, and adhere excellently to almost all building materials, even on damp substrates.
Moreover, they remain elastic, shrink-free and are paintable with most paints.
Parabond MS polymer sealants from DL Chemicals are used for both sealing and bonding in construction, finishing and industry.
