"All-rounder" in the oil-proofing world: the core competitiveness and application value of PU varnish
oil-proofing agent
PU varnish oil-proofing agent introduces functional ingredients into the PU varnish system to significantly improve
the coating's anti-oil, anti-fingerprint, easy-to-clean properties, while maintaining the original characteristics of the
material. Its application advantages can be comprehensively analyzed from the dimensions of performance
improvement, cost-effectiveness, environmental protection and user experience, as follows:
1. Core performance advantages
Excellent anti-oil ability
Principle: The oil-proofing agent reduces the surface energy, making it difficult for oil (such as grease, sweat, and
cosmetic residue) to adhere to the coating surface, forming a "lotus effect".
Effect: The water drop angle on the coating surface can be increased to more than 100°, and the oil drop contact angle
exceeds 120°. The oil can be easily wiped or naturally slide off, reducing the difficulty of cleaning.
Application scenarios: mobile phone screens, home appliance panels, food packaging and other surfaces that need to
frequently contact oil.
Anti-fingerprint and self-cleaning properties
Principle: The oil-repellent forms a microscopic rough structure or a low surface energy film layer on the coating
surface, reducing the penetration and residue of fingerprint grease.
Effect: The fingerprint residue is reduced by more than 80%, the surface stains can be easily wiped off with a wet cloth,
and it remains smooth after long-term use.
Application scenarios: high-end electronic products (such as smart watches, tablets), automotive interiors and other
fields with high requirements for surface aesthetics.
Enhance the durability of the coating
Principle: The oil-repellent forms chemical bonds or physical cross-links with the PU varnish molecular chain to improve the
hardness, wear resistance and chemical corrosion resistance of the coating.
Effect: The wear resistance of the coating is improved by 30%-50%, the anti-scratch performance is significantly enhanced,
and the service life of the material is extended.
Application scenarios: Furniture surfaces, floor coatings, industrial equipment housings and other scenes that are
susceptible to wear.
2. Cost and efficiency advantages
Reduce long-term maintenance costs
Reduce the frequency of cleaning: The oil-repellent coating can reduce the need for daily cleaning and reduce labor and
detergent costs.
Extend the renovation cycle: the durability of the coating is improved, the aging of materials or the shedding of the coating
caused by oil penetration is reduced, and the service life of the product is extended.
Case: After the tabletop of the catering place is coated with oil repellent, the cleaning time is reduced by 40% and the
renovation frequency is reduced by 50%.
Simplify the production process
Strong compatibility: the oil repellent can be directly mixed with the existing PU varnish system without additional
equipment or process adjustment.
High curing efficiency: it is cured synchronously with the PU varnish, does not increase the production time, and is suitable
for large-scale industrial applications.
Data: After a home appliance company introduced the oil repellent, the production line efficiency increased by 15% and the
defective rate decreased by 10%.
3. Environmental protection and safety advantages
Low VOCs emissions
Environmentally friendly formula: modern oil repellents use water-based or low-solvent systems, and the VOCs content is
60%-80% lower than traditional
products, which complies with environmental protection regulations such as EU REACH and China GB.
Application scenarios: fields with strict environmental protection requirements such as interior decoration and children's toys.
Non-toxic and harmless
Safety certification: Passed RoHS, FDA and other certifications, the oil-repellent ingredients are non-toxic and harmless to the
human body, and are suitable for food contact materials (such as tableware, packaging).
Case: After a food packaging company used oil-repellent, the product passed FDA testing and market acceptance increased.
4 Improve user experience and market competitiveness
Increase product added value
Differentiation selling points: Oil-resistance and easy-to-clean functions have become product highlights, meeting consumers'
demand for high-quality life.
Data: The premium space of electronic products equipped with oil-repellent coatings can reach 10%-20%, and market sales
have increased by more than 25%.
Enhance brand reputation
User satisfaction: Reduce oil pollution troubles, improve product experience, and enhance user loyalty.
Case: After a mobile phone brand launched an oil-resistant screen, the user praise rate increased by 30%, and the repurchase
rate increased by 15%.
5. Industry adaptability and scalability
Multi-substrate compatibility
Wide range of application: Oil-repellent can be applied to a variety of substrates such as plastics (such as PC, ABS), metals
(such as stainless steel, aluminum alloy), glass, ceramics, leather, etc.
Case: In car interiors, oil repellent is used for plastic center consoles, leather seats and metal decorative strips at the same time
to achieve oil-resistant effect for the whole car.
Functional compounding
Synergistic enhancement: Oil repellent can be compounded with antibacterial agents, UV protection agents, wear-resistant
agents, etc. to achieve "one coating with multiple effects".
Application scenarios: medical equipment (oil-resistant + antibacterial), outdoor furniture (oil-resistant + weather-resistant), etc.
Summary
PU varnish oil repellent significantly optimizes product performance, reduces maintenance costs, and enhances market
competitiveness by improving the oil resistance, durability and environmental protection of the coating. Its core advantages can
be summarized as follows:
Performance side: oil resistance, fingerprint resistance, wear resistance;
Cost side: cost reduction and efficiency improvement, extended life;
Environmental protection side: low VOCs, safety and compliance;
Market side: increase added value and enhance brand power.
Against the background of consumption upgrading and stricter environmental regulations, PU varnish oil repellent has become
one of the core materials in high-end manufacturing, home decoration, electronic appliances and other fields, and has broad
application prospects in the future.
