Getsun, a flagship brand of Guangzhou Helioson Car Care Co., Ltd., has become a benchmark in the paint protection industry with over 20 years of dedication and innovation. Getsun's Paint Protection Film (PPF), commonly known as "invisible car wrap," offers comprehensive paint protection with its exceptional physical defense, cutting-edge self-healing technology, and eco-friendly properties. This article delves into the origins, structure, functions, materials, and necessity of applying Getsun's PPF, providing an in-depth look at this premium paint protection product.
The Origins of Paint Protection Film and Getsun's Brand Mission
The term "Paint Protective Film" (PPF) directly translates to "paint protection film," with its core function being to provide a physical barrier for the vehicle's paint against external damage. Historically, this type of product was referred to as "rhino skin" or "car paint protection film," but today, "invisible car wrap" is more widely recognized due to its transparency and seamless application. Since its founding in 2008, Getsun has focused on paint protection, adhering to the corporate philosophy of "going beyond the past, never settling for the present." The brand continuously drives technological innovation, upgrading traditional chemical protection to more efficient and durable physical protection.
Getsun is not only committed to preserving the original shine of car paint but also provides aesthetically pleasing and practical solutions through innovative materials and processes. Whether it's a family sedan for city commuting or an SUV for off-road adventures, Getsun's PPF offers tailored protection, ensuring that every vehicle remains radiant through the test of time.
The Five-Layer Structure and Technical Excellence of PPF
Getsun's PPF features an advanced five-layer design, with each layer meticulously engineered to achieve the perfect balance of protection, ease of application, and long-term durability. The structure is detailed as follows:
1.Protective Layer: The outermost layer, transparent and relatively hard, protects the film from damage during transportation, cutting, or storage. It is removed before cutting the film.
2.Self-Healing Coating: Approximately 0.8-1 mil thick, this is the "technological core" of the PPF. It offers scratch self-healing capabilities, available in heat-activated (reaction temperature around 60°C) and instant self-healing (reacts at room temperature or lower) variants. Through principles of thermal expansion and contraction, molecular reorganization, and fluidity, minor scratches disappear quickly under heat or natural conditions, keeping the film surface smooth.
3.TPU Substrate: About 6 mil thick, this is the core support of the film, made from Thermoplastic Polyurethane (TPU). TPU boasts excellent stretchability, abrasion resistance, and tolerance to high and low temperatures, providing the primary physical protection against scratches, stone chips, and other external forces.
4.Pressure-Sensitive Adhesive: Ensures a secure bond between the film and the paint, with moderate adhesion that leaves no residue or damage upon removal, offering safe and stable attachment.
5.Adhesive Protection Layer: A white backing layer removed before application, it protects the adhesive from dust or contamination during installation.
Self-Healing Coating: Cutting-Edge Scratch Repair
The self-healing coating is the standout feature of Getsun's PPF. Its softness and toughness prevent the film from cracking under tension or stress, avoiding common issues like yellowing, water spots, or cracking. A high-quality coating feels slightly rough to the touch with moderate water repellency, while inferior coatings are hard, smooth, and overly water-repellent. Quality can be assessed through:
Visual Test: Cut a 2 cm wide, 10 cm long strip of film and slowly stretch it to observe if the coating develops cracks or lines. A premium coating remains flexible with even lines; an inferior one cracks easily.
Touch Test: A premium coating feels soft and slightly grippy; an inferior one feels hard and slick, like plastic.
Marker Test: Draw on the coating with a marker; a premium coating resists ink adhesion and is easy to wipe clean.
TPU Substrate: A Resilient Physical Barrier
The TPU substrate serves as the "armor" of the PPF, composed of a linear block copolymer made from oligomer polyol soft segments and diisocyanate-chain extender hard segments. Getsun uses aliphatic TPU, which offers superior advantages over aromatic TPU:
Chemical Resistance: Withstands acid rain, bird droppings, and other corrosive substances.
Aging Resistance: Free of phenyl groups, preventing yellowing and degradation under UV exposure.
Mechanical Properties: High tensile strength, wear-resistant, water-resistant, oil-resistant, and mold-resistant.
In contrast, the commonly found TPH (PVC with plasticizers) is cheaper but far inferior in performance. TPH is brittle, lacks scratch resistance, yellows easily, and can be torn by hand. Getsun's TPU substrate can be easily distinguished by:
Color: TPU is transparent with a slight yellow tint; TPH has a blue tint.
Tear Test: TPU cannot be torn by hand; TPH tears easily.
Stretch Test: A 2 cm wide strip of TPU requires significant force to stretch, while TPH needs only wrist strength.
Texture: TPU shows even stretch marks and only breaks when fully stretched; TPH shows few marks and breaks quickly.
Flat Lay: TPU drapes when laid flat; TPH remains straight.
Pressure-Sensitive Adhesive: Secure and Safe Bonding
Getsun's adhesive is rigorously selected to ensure it is odorless, non-sticky upon removal, and leaves no residue. Quality can be verified by:
Smell: Premium adhesive has no pungent odor.
Touch: No stickiness on hands after removal.
Scratch Test: With the adhesive side up, press the film with one hand and scratch with a fingernail 10 times; premium adhesive shows no bright spots or damage.
The Necessity of Applying Paint Protection Film
The original factory paint is the "soul" of a vehicle, accounting for approximately 25%-40% of its value, and is irreplaceable. Repainting or touch-ups can never match the quality and durability of the original paint, making its protection crucial. The original paint consists of five layers:
1.Phosphating Layer: Forms a dense passivation layer to prevent metal corrosion.
2.Electrophoretic Layer: Adheres to the metal body for rust prevention.
3.Mid-Coat Layer: Enhances corrosion protection, smooths the surface, and provides adhesion for the color coat.
4.Color Coat: Displays the vehicle's color and further prevents corrosion.
5.Clear Coat: Protects the color coat from minor scratches and fading.
The clear coat, being the outermost layer, is highly susceptible to chemical damage (e.g., oxidation, fading, water spots, corrosion, traffic film) and physical damage (e.g., scratches, abrasions, cracking). Getsun's PPF provides dual physical and chemical protection, creating a robust defense for the paint. Its necessity is evident in:
1.Scratch Resistance: Protects against parking lot scrapes, lane-changing friction, and roadside scratches.
2.Chemical Corrosion Resistance: Prevents damage from acid rain, bird droppings, insect residue, tree sap, and asphalt.
3.UV and Oxidation Blocking: Isolates UV rays, slows paint oil evaporation, and prevents yellowing of white cars or dulling of black cars.
4.Impact and Chip Protection: Absorbs impacts from high-speed stones, hail, or falling objects.
5.Enhanced Aesthetics and Feel: Mirror-like reflection boosts paint gloss, with a soft, seamless touch.
6.Easy Cleaning and Low Maintenance: Hydrophobic and stain-resistant properties make dirt rinse off easily, eliminating the need for waxing or sealing.
7.Vehicle Value Preservation: Maintains the integrity of the original paint, enhancing resale value.
