The exterior paints are typically higher quality than interior and contain special chemicals to resist sunlight-induced fading.
How To Protect PVC Pipe From Sunlight
PVC pipe stands for polyvinyl chloride. When this was invented, it was a great tool in replacing metal or lead pipes. Now, PVC pipes have become the most commonly used pipes for plumbing and drainage.
Second Paint Layer For Pvc Pipe Protection
After you have applied the primer, you can move to your second and final layer of paint. This is a similar process to when you paint a wall. The primer makes it so the next layer of paint will stick to the wall properly without flaking.
Is There A UV-Resistant PVC Pipe?
In general, we could argue that all PVC pipes are UV resistant to an extent. However, just because they are resistant does not mean that they will survive under long amounts of exposure to the sun. They can last a few hours but once you do this on a daily basis, the stress continues to build on the pipe, causing it to break.
How does UV affect plastic?
The higher energy UVC is the type most likely to affect plastics. Absorbed UV energy can excite the photons in a plastic. Those free radicals can cause breaks in the polymer bonds.
How to prevent UV damage?
UV attack by sunlight can be ameliorated or prevented by adding anti-UV polymer stabilizers, usually prior to shaping the product by injection moulding. UV stabilizers in plastics usually act by absorbing the UV radiation preferentially, and dissipating the energy as low-level heat.
Is UV radiation harmful to acrylonitrile?
Answer: Ultraviolet (UV) radiation would be more harmful to acrylonitrile-butadiene-styrene (ABS) used outdoors than the heat and cold. Therefore, it should be coated with a pigmented material (paint) for UV protection.
Why is plastic used in cars?
Because of the variety of possible forms, safety considerations and the significant weight savings , the automotive industry is increasingly using plastic components. On average, today's car consists of 14% of various types of plastic. The organic material is, however, subject to a natural aging process that makes the addition of stabilizers necessary. Exposure to sunlight accelerates the process. Often, such plastic components are treated with a topcoat. However, due to undesired migration, the concentration of stabilizer in the plastic and coating decreases over time. The plastic, as well as the coating, is then no longer sufficiently protected. This article describes the mechanism of migration and explains possible methods of delaying it.
How does UV absorption work?
Most UV absorbers function according to similar mechanisms. The physical absorption process protects both the deeper sections of the coating and the substrate from the high-energy fractions of sunlight. These are absorbed and lead to isomerization, causing the molecule to transform into an excited structure. When the molecule reverts to its original condition, the absorber releases the energy into the environment as thermal energy. The relevant UV absorbers in coatings include 2-hydroxybenzophenones, oxalanilides, 2-hydroxyphenylbenzotriazoles and 2-hydroxy-phenyltriazines.
What is hals in plastic?
Harmonization of Plastics and Coating Stabilizer. HALS stabilize both the plastic and the coating. In the protective coating, the HALS operate together with a suitable UV absorber as light stabilizers. In plastics, on the other hand, they are often needed for process stabilization.
Why use identical stabilizers in plastic?
Otherwise the additive concentration in the protective layer drops significantly due to the extremely high level of migration, causing stabilization to become ineffective. The adhesive properties of the coating decrease, the component is subject to rapid discoloration and loss of gloss.
What is UV stabilization?
The UV stabilization is an indispensable element of the plastic coating in the automobile exterior. In ideal circumstances, these are multi-layer systems. The coating of plastics begins with the application of a primer, which has a binding effect on the basecoat, that is then applied over the primer. Finally, a clearcoat containing the light stabilizers for UV protection seals the coating system.
How much plastic is in a car?
On average, today's car consists of 14% of various types of plastic. The organic material is, however, subject to a natural aging process that makes the addition of stabilizers necessary. Exposure to sunlight accelerates the process. Often, such plastic components are treated with a topcoat.
