Ford tests paint with artificial bird droppingsMay 8, 2020
Ford Corporation uses synthetic bird droppings to test the durability of the paintwork.
This substance was developed in the laboratory and is so similar to a natural analogue that the concern can even imitate the different acidity of many species of birds that live in Europe.
Synthetic poultry manure is a spray that is sprayed onto painted test panels and then subjected to artificial aging by heating in an oven to 40, 50 and 60 degrees Celsius. So, the production simulates the summer heat when, due to sunlight, the paint becomes soft and stretches, and when it cools, it shrinks, gluing droppings to the surface of the body. By changing the composition of pigments, resins and various additives in the paint, specialists have the opportunity to minimize the effects of excrement and uric acid on it.
In addition to artificial manure, Ford uses a spray that includes phosphoric acid, soap-based detergent and synthetic pollen. It is also sprayed onto the panel and baked for half an hour at a temperature of 60 or 80 degrees Celsius. This test makes it possible to evaluate the protection of the paint from all kinds of particles, such as pollen and sticky wood juice.
Finally, all experimental paint samples are irradiated with ultraviolet light for 6,000 hours — the equivalent of 5 years that were spent under the bright sun — they are frozen in a cryochamber, exposed to reagents and spilled fuel.
