The freshly pasted car coat was high-definition and translucent, but it didn't take long for it to start to dirt and become dumb and dull. In such a situation, you need to pay attention to the following three reasons are the most likely to be caused!
1. Improper over-stretching construction
| Solution |
When encountering parts with large arcs, such as bumpers, reflector corners, etc., do not overstretch and damage the coating, and keep the film surface and the paint surface fully lubricated, so that the film surface will be evenly stressed during stretching, and prevent local overstretching from causing the film surface to become matte and lose light. If there has been a local muteness, but it is found in time, it can be recovered by baking a gun and heating with hot water.
2. The substrate and coating are caused
PVC, TPH, and some domestic substrate TPU material car clothing, in order to pursue better flexibility, often add excessive plasticizers, once the plasticizer precipitation will cause dumbness, dirt, not only that, plasticizer precipitation will also cause the adhesive layer to fall off, produce offset printing on the paint surface, and eventually corrode the car paint.
At present, the coating coating on the market can be divided into two types: second repair and self-healing. Among them, the TPU clothing coated in seconds has been loved by stores for a period of time in the past due to its good ductility and easy construction. However, the coating of the second repair TPU is too soft, the coating density is not enough, the hydrophobicity and stain resistance are poor, and it cannot effectively block particles and impurities such as PM2.5, and the surface of the TPU will become dumb and polluted over time.
In order to meet the demand for brightness in the car clothing market, some manufacturers add a high-brightness curing agent to the coating, which contains a double bond structure in the curing agent structure, which has poor weather resistance, and is very prone to double bond fracture under the irradiation of sunlight and ultraviolet rays, resulting in insufficient density of the coating to effectively resist the erosion of external substances, resulting in dumbness and pollution.
- It is difficult for consumers to avoid buying PVC or TPH car clothing from the source, so they should choose the polycaprolactone aliphatic TPU material clothing of the regular car clothing brand, and the official store designated by the brand will carry out the construction, and let the store enter the formal electronic warranty for the film vehicle as soon as possible, which can protect your legitimate rights and interests to the greatest extent.
- Manufacturers, sellers, and consumers should make it clear that only with superior comprehensive performance can the protective function and service life of invisible clothing be lasting. The blind pursuit of single-point prominence is an act of putting the cart before the horse, because behind one extreme performance, it must come at the expense of other performance.
3. Caused by external corrosion
Strong acids and alkalis such as bird droppings, insect corpses, gums, air conditioning water, oil smoke, acid rain and other strong acids and alkalis will cause the coating to be corroded, resulting in dumb and dirty clothing, and the longer the accumulation time, the more serious the degree of corrosion, which cannot be ignored.
