Bayflex 190 is an ELPO (electrophoresis-capable) high-performance polyurea with excellent heat stability, low moisture absorption, low thermal expansion characteristics, and excellent impact resistance. Parts made from this material have superior surface and paint adhesion qualities and have a DOI (Distinction of Image) comparable to painted steel parts. The Bayflex 190 system is an excellent choice for applications such as truck fenders and tailgates. As with any product, use of the Bayflex 190 system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability. Bayflex 190 is a formulated RIM system, supplied as two liquid components. Component A is a diphenylmethane diisocyanate (MDI) prepolymer and Component B is a polyether amine system. |
