Advantages of water-based plastic paint oil repellent: a tool for innovation in coating quality
Today, with the widespread use of plastic products, water-based plastic paint has become the mainstream choice for surface
coating due to its environmental protection and safety characteristics. However, problems such as oil stains on the substrate
and residual release agent often lead to defects such as shrinkage holes and oil spots in the paint film. The emergence of
water-based plastic paint oil repellent has effectively resolved these problems, brought significant advantages to the coating
industry, and become the key to improving product quality.
1. Efficiently solve paint film defects and improve product appearance quality
The most prominent advantage of water-based plastic paint oil repellent is that it can efficiently solve paint film defects. Its
core function is to reduce the surface tension of the coating film and improve the wettability of the coating to the substrate.
When there is oil stain or release agent residue on the substrate, ordinary water-based plastic paint is prone to form shrinkage
holes, oil spots and other defects due to uneven surface tension. Take a certain electronic shell coating company as an example.
Before the introduction of oil-repellent agent, the shrinkage problem caused by the residual release agent caused the product
defect rate to be as high as 15%; after using non-silicone modified polymer oil-repellent agent, by reducing the static and dynamic
surface tension, the coating can also be evenly spread on the oily substrate, and the defect rate dropped sharply to 3%. The surface
of the product is smooth and flat, which greatly improves the appearance quality. In the coating of automotive interior plastic parts,
oil-repellent agent can also prevent oil stains caused by contact with human oils and fats, and always keep the coating beautiful.
2. Significantly improve production efficiency and reduce overall costs
Oil-repellent agent greatly improves production efficiency and reduces overall costs by reducing paint film defects. In traditional
coating production, rework and scrapping caused by paint film problems are frequent, which wastes time and increases material and
labor costs. The application of oil-repellent agent effectively reduces these losses. After a toy manufacturing company used oil-repellent,
the number of reworks caused by coating defects decreased by about 40 times per month. Based on the calculation that each rework
takes 2 hours and the labor cost is 50 yuan per hour, the labor cost alone saves 4,000 yuan per month; at the same time, the material loss
is reduced by about 12%, which can save hundreds of thousands of yuan in production costs each year, significantly improving the
company's economic benefits.
3. Enhance the comprehensive performance of the coating and extend the service life of the product
The oil-repellent can not only improve the appearance of the paint film, but also enhance the comprehensive performance of the coating.
It can improve the adhesion of the coating to the substrate and make the coating closely combined with the plastic substrate. In the
coating of outdoor plastic products such as plastic tables and chairs, awnings, etc., the coating formed by the oil-repellent agent has an
anti-scratch and wear resistance of about 30%, and the weather resistance is also significantly enhanced. It can better resist ultraviolet rays
and rain erosion, extend the service life of the product, reduce the frequency of product replacement due to coating damage, and reduce
the cost of use for consumers.
4. Meet environmental protection needs and ensure production safety
With the increase of environmental awareness, the advantages of water-based plastic paint oil repellent in environmental protection and
safety are becoming more and more prominent. Most water-based oil repellents use environmentally friendly raw materials, are non-toxic,
odorless, and do not contain volatile organic compounds (VOCs), which meet national environmental protection standards and regulatory
requirements. During the production process, the irritating odor and harmful gas emissions caused by traditional oil-based oil repellents
are avoided, creating a healthy working environment for operators, while also reducing pollution to the surrounding ecological
environment, and achieving a harmonious unity of production and environmental protection.
Water-based plastic paint oil repellent has become an indispensable additive for modern plastic coating with its significant advantages
in solving paint film defects, improving production efficiency, enhancing coating performance and meeting environmental protection
needs. In the future, with the continuous innovation of technology, oil repellents will continue to make breakthroughs in performance
and application fields, providing stronger support for the high-quality development of the plastic coating industry.
