DESMODUR VL 51 is an aromatic polyisocyanate based on diphenylmethane diisocyanate. It has a lower viscosity when mixed with other polyols compared to DESMODUR VL. This results in more flexible end-products for applications. DESMODUR VL 51 is commonly used in the formulation of prepolymers for one- and two-component systems. It offers easier handling compared to other alternatives. The product is well-suited for formulations requiring flexibility and ease of application. DESMODUR VL 51 allows formulating coatings and sealants with an improved balance of properties.
