герметики

A two-component sealant based on polyurethane.

Designed to protect against water and air permeability of inter-panel expansion joints, joints and cracks in building structures both inside and outside residential and industrial premises; sealing expansion joints of building structures with a maximum deformation of 25%; sealing double-glazed windows; sealing joints, cracks and cracks. It is easy to apply manually with a spatula. It cures as a result of the chemical reaction of the sealant components with each other. It can be painted with water-dispersion paints
