MS 609

Flexible Polyurethane Joint Sealant

 

Obaproof MS 609 is a low modulus, one component, flexible polyurethane joint sealant. When cured it will form a tough, flexible seal capable of cyclic expansion and compression movement. Obaproof MS 609 can be applied on external surfaces, exposable to UV and the normal weather condition. It is odourless and a non-sagging paste.
