Guide to using plastic paint anti-oil agent: unlock a new experience of efficient anti-fouling
In the era of widespread use of plastic products, plastic paint not only gives products gorgeous colors and
beautiful appearance, but also bears the important responsibility of protecting the substrate. However, oil
pollution is always around, seriously affecting the beauty and service life of plastic products. The emergence
of plastic paint anti-oil agent provides an effective solution to this problem. But in order to give full play to
its advantages, the correct method of use is crucial. Here is a detailed introduction to the use of plastic paint
anti-oil agent.
Before use: Careful preparation and laying the foundation
Choosing the right product is the key
There are many types of plastic paint anti-oil agents on the market with different performances. When choosing,
you should fully consider the material, use environment and required anti-fouling effect of the plastic product.
For example, for plastic products used in oily environments such as kitchens, you should choose an anti-oil agent
with super oleophobic properties; and for some children's toy plastic shells with high environmental requirements,
you should choose an environmentally friendly anti-oil agent. At the same time, it is necessary to ensure that the
selected oil-repellent agent has good compatibility with the plastic paint used to avoid peeling, discoloration and
other problems caused by incompatibility.
Substrate treatment is essential
Before adding the oil-repellent agent, the plastic substrate must be thoroughly cleaned. Because the dust, oil,
impurities on the surface of the substrate will affect the adhesion of the plastic paint to the substrate, and thus affect
the effect of the oil-repellent agent. You can use a special cleaner and a clean cloth to wipe the surface of the substrate
to ensure that it is clean, dry and oil-free. For some plastic substrates with rough surfaces, appropriate polishing can
also be performed to increase the surface area of the substrate and improve the adhesion of the paint layer.
Accurate mixing ratio
Different plastic paint oil-repellent agents have different recommended addition ratios, and they must be mixed
strictly in accordance with the requirements of the product manual. If the addition ratio is too high, the viscosity of
the plastic paint may be too high, affecting the construction performance, and even causing problems such as
sagging and bubbling; if the addition ratio is too low, the expected anti-fouling effect cannot be achieved. When
mixing, you can use precise measuring tools, such as electronic scales, measuring cups, etc., to ensure that the ratio
of oil-repellent agent to plastic paint is accurate. At the same time, the oil-resistant agent should be slowly added to
the plastic paint and stirred evenly to avoid local concentrations that are too high or too low.
In use: standardize operations to ensure quality
There are requirements for the construction environment
The temperature, humidity and cleanliness of the construction environment have an important impact on the effect of
the plastic paint oil-resistant agent. Generally speaking, the suitable construction temperature is 15℃ - 30℃. Too low a
temperature will cause the plastic paint to dry slowly, affecting the construction progress and the quality of the paint
layer; too high a temperature may cause the plastic paint to dry too quickly, resulting in problems such as rough surface
and low gloss. The humidity of the construction environment should be controlled below 60% relative humidity. Too high
humidity can easily cause the paint layer to turn white and bubble. In addition, the construction site should be kept clean
to prevent dust and debris from falling into the paint layer, affecting the appearance quality.
The construction method should be appropriate
Common plastic paint construction methods include spraying, brushing and rolling, and different construction methods
are suitable for different products and scenarios. Spraying is suitable for large-area, regular-shaped plastic products, and
can obtain a uniform and smooth paint layer effect, but it requires professional spraying equipment and certain operating
skills. Brushing is suitable for small-area, complex-shaped plastic products. The operation is relatively simple, but it is easy
to have brush marks, and you need to pay attention to the strength and direction of brushing. Rolling has a higher
construction efficiency and a relatively uniform paint layer thickness, but it may not be as delicate as spraying and brushing.
When choosing a construction method, it is necessary to make a reasonable choice based on the characteristics and
requirements of the plastic products, and strictly follow the corresponding construction specifications.
Layered coating has a good effect
In order to ensure that the plastic paint oil repellent can fully play its role, it is recommended to use a layered coating method.
First, apply a layer of primer, which can enhance the adhesion of the plastic paint to the substrate, and at the same time fill the
tiny pores on the surface of the substrate to make the paint layer smoother. After the primer is dry, apply the topcoat. The
topcoat contains an oil repellent, which can form an effective antifouling layer. During the painting process, pay attention
to the drying time of each layer of paint, and ensure that the previous layer of paint is completely dry before applying the
next layer of paint to avoid the problem of poor interlayer adhesion.
After use: Careful maintenance to extend the life
Drying and curing requires patience
After the painting is completed, the plastic paint must have enough time to dry and cure. Different combinations of plastic
paint and oil repellents have different drying and curing times, generally requiring 24-72 hours. During the drying and
curing period, avoid touching, moving or covering the plastic products to avoid affecting the flatness and glossiness of the
paint layer. At the same time, keep the construction environment well ventilated to accelerate the volatilization of the solvent
in the paint layer and promote the drying and curing process.
Regular maintenance is indispensable
Although the plastic paint oil repellent can provide good anti-fouling performance, it may still be eroded by oil, dust, etc.
during long-term use. Therefore, plastic products need to be cleaned and maintained regularly. You can use a mild detergent
and a soft cloth to wipe the surface to remove stains and dust. For some stubborn oil stains, you can use a special
decontaminant to deal with them, but be careful not to use too strong chemical cleaners to avoid damaging the paint layer.
Proper storage to maintain performance
If there is any oil repellent left during use, it needs to be properly stored. The oil repellent should be placed in a cool, dry,
well-ventilated place, away from direct sunlight and high temperature environment, because high temperature may cause
the performance of the oil repellent to change or even fail. At the same time, the container should be sealed to prevent
the oil repellent from volatilizing or being contaminated. When using it next time, check whether the appearance and
performance of the oil repellent are normal. If there is any abnormality, stop using it.
The use of plastic paint oil repellent is a systematic and meticulous process. From careful preparation before use, to
standardized operation during use, to careful maintenance after use, every link is related to the final anti-fouling
effect and the quality of plastic products. Only by mastering the correct use method can the advantages of plastic
paint oil repellent be fully utilized, so that plastic products can always remain beautiful and clean, and their service
life can be extended.
