PUT-5701 is FIPFG – Formed In Place Foam Gaskets which help to meet the demand for sealing quality and contour-accurate tightness of the components. PUT -5701 consists of a fluid to paste-like A-component (polyol) with varying molecular chain lengths for soft and hard foams and a hardener, the B-component (MDI). When mixing and curing, a soft foam seal is formed which cures at room temperature, without the use of a tempering furnace.
