The number one acknowledged after-sales nightmare in the invisible car PPF industry is none other than hydrolysis!
The PPF, base layer and glue all dissolve together and turn into a paste that needs to be removed with a hard scraper or even a spatula, causing serious irreversible damage to the original car paint.
Today, we’ll take you through the causes and solutions of hydrolysis
01.What causes hydrolysis?
How can a ppf that was originally applied to protect your car paint become the thing that hurt the original car paint
It’s because you bought a car ppf made with a polyester TPU base material!
Due to the presence of hydrolysable ester groups, polyester TPU is susceptible to water molecules causing molecular chain breakage, and the acid generated by hydrolysis can catalyse further hydrolysis of polyester, and eventually, under the combined attack of light and rain, the TPU will completely disintegrate into a paste.
Eventually, when exposed to light and rain, the TPU in its original form breaks down into a paste that adheres to the car body.
02.When does hydrolysis break out?
When does hydrolysis usually break out?
Applied with easy hydrolysis of polyester TPU car PPF, generally problem outbreaks after 6 months to 3 years after installation, the outbreak of time mainly depends on the local rainfall frequency, climate, temperature and Daily parking locations for vehicles, the more rain, the higher the temperature, When the vehicle is parked mostly in the open environment , hydrolysis appeared relatively faster.
03.What to do after hydrolysis?
As the recognized number one nightmare in the car ppf industry, hydrolysis is definitely the most serious aftermarket problem, The difficulty of dealing with it and the depth of damage to the original car paint are both daunting. Before the problem of hydrolysis can not hold any fluke mentality, think that only need to replace the hydrolysis parts of the film, other parts of the car ppf can still be used normally. You should know that hydrolysis = no solution, once the phenomenon of partial hydrolysis occurs, as long as the same roll of film is applied, the tragic end of the whole car hydrolysis is the nail in the coffin, it is only a matter of time. The basis for judging hydrolysis is that the film has already shown signs of pulverization, tearing the film by hand will appear powdered off, and even attached to the body of the car.
For the first signs of hydrolysis, the owner should immediately contact the store to remove the film from the whole car, to avoid the serious consequences of a large area of hydrolysis causing the original paint to be scrapped; and the store should, in the face of the hydrolysis of the car ppf, according to the degree of hydrolysis, respectively, 1 tear 2 shovel 3 spray operation: if the degree of hydrolysis is light, priority should be given to trying to tear the film manually, to try to avoid causing damage to the original paint. If the hydrolyzed car ppf has been dissolved in the car body, it should be removed with the solvent of adhesive remover, and finally spray paint treatment on the partial removal part or the whole car paint surface
How to avoid hydrolysis?
Finally, back to the topic that everyone is concerned about – how should hydrolysis be avoided?
If you want to avoid the problem of hydrolysis, the whole industry should work together to adhere to the foundation of the industry, fully learn from the lessons of the industry in the past, and keep the base material and production of the two major hurdles, in order to create a reliable and sustainable market environment, to avoid the problem of hydrolysis from the source.
CAXVINYL as the most trustworthy and an experienced professional manufacturer of the PPF after decades of market baptism and witnessing the iteration and optimization of raw materials, we choose polycaprolactone aliphatic TPU masterbatches as the base material,which has excellent mechanical strength, oil resistance, chemical resistance, abrasion resistance and tear strength, and there is no ester group that is relatively easy to hydrolyze,which ensures the durability of the ppf and safely protect the original car paint
