Fast-Reacting Bumper System
The image above shows a cross-section of a fast-reacting, composite polymer for high-performance automotive applications. Originally developed for Rolls-Royce bumpers, the product consists of three major components, manufactured in an open mould, using a spray-applied technique. The first part of the operation consists of a spray-applied in-mould, self-releasing black paint. The second layer consists of a 1:1 polyurea elastomer, providing a very high impact material for the essential bumper structure. This layer cures in about fifteen seconds, after which an open cell, energy absorbing polyurethane is applied. The whole process takes about three minutes to complete, resulting in a bumper, which is virtually indestructible.
