Raku-Tool PH-3923 PU Hardener flexible 1kg

The Raku-Tool PH-3923 PU-Hardener is a versatile, flexible hardener specifically developed for use with the polyols Raku-Tool PC-3412 and PC-3413. This combination enables the production of flexible polyurethane casting resins with a Shore hardness of A40 to A85. The product is easy to process by hand and does not require skull labeling, making it safer to use. It is excellent for structural matrices, workpiece holders, impact protection parts, and the production of flexible components. The yellowish color and high processing quality guarantee precise results that withstand high stresses. With a short pot life and curing at room temperature or moderate heat, it offers flexibility in production. Additionally, it is available in both small and larger packaging units to meet different needs. The storage of the hardener is simple, as it remains stable at temperatures between 15 °C and 25 °C. This product is a reliable solution for professional applications.
