What You'll Learn
Use UV-resistant sprays or lacquers
One of the most effective methods to protect plastic from sun damage is to use UV-resistant sprays or lacquers. These sprays are designed to be applied directly to the surface of the plastic, providing a protective layer that shields the material from the sun's harmful UV rays. This method is particularly useful for outdoor items that are constantly exposed to direct sunlight, such as patio furniture, garden decor, and plastic components of power tools.
There are a variety of UV-resistant sprays and lacquers available on the market, each designed to suit specific needs. For example, Marinamax offers an Ultimate UV Protection Spray that is suitable for a wide range of materials, including vinyl, rubber, plastic, plexiglass, and leather. This spray-on application is easy to use and can be applied to surfaces with a simple spray and wipe-down process. It is recommended to apply this type of product every 3-5 weeks to maintain optimal UV protection.
Another option is to use paint designed to bond with plastic and offer UV protection. Paints such as Krylon Fusion for Plastic and Rustoleum Specialty for Plastic are known to provide protection against UV degradation while also enhancing the appearance of the surface. These paints may require light sanding of the plastic surface before application and may have longer recoat and cure times compared to other options.
When choosing a UV-resistant spray or lacquer, it is important to consider the specific type of plastic and its intended use. Some plastics, such as acrylic, polycarbonate, and ABS plastics, are naturally more resistant to sunlight damage and may require less frequent applications of protective coatings. Additionally, it is always a good idea to read the product's instructions and your furniture's warranty to ensure that the use of such products will not void the warranty.
By using UV-resistant sprays or lacquers, you can effectively protect plastic items from sun damage, ensuring their longevity and maintaining their aesthetic appeal. These protective coatings act as a barrier, reducing the impact of UV radiation and preventing issues such as discoloration, fading, and cracking. With proper application and regular maintenance, these products can significantly extend the lifespan of your plastic belongings.

Store plastic items in a sheltered area
Sunlight can cause significant damage to plastic, affecting its quality, performance, and durability. The leading causes of sunlight damage to plastic are ultraviolet (UV) and infrared (IR) radiation. Therefore, it is essential to store plastic items in a sheltered area to minimize sun damage. Here are some detailed, direct, and instructive guidelines on storing plastic items in a sheltered area to protect them from sun damage:
Firstly, identify a suitable sheltered area to store your plastic items. This could be a shed, garage, basement, or any indoor space that is away from direct sunlight. The chosen area should be cool, dry, and well-ventilated to prevent moisture buildup, which could promote the growth of mould or mildew on the plastic items. Ensure that the sheltered area is easily accessible so that you can regularly monitor and maintain your plastic items.
Secondly, when placing plastic items in the designated sheltered area, make sure to clean them beforehand. Use a mild soap or detergent and water solution to wipe down the plastic surfaces, removing any dirt, dust, or debris that may have accumulated. Completely dry the plastic items before storing them to prevent the growth of mildew or mould.
Additionally, you can utilize storage containers or boxes to organize and protect your plastic items within the sheltered area. Clear plastic containers with secure lids are ideal as they allow you to easily identify the stored items while providing protection from dust and insects. If using cardboard boxes, ensure they are sturdy and in good condition, and consider lining them with acid-free tissue paper or cotton cloth to provide a barrier between the plastic items and the box material.
Moreover, it is beneficial to arrange the plastic items neatly and in a way that promotes air circulation. Avoid stacking or crowding the items too closely together, as this can trap moisture and encourage the growth of mildew. You can use shelves or racks to create additional storage space and improve air circulation around the stored items.
Finally, regularly inspect your plastic items for any signs of sun damage, such as discoloration, fading, or cracking. If you notice any damage, you can consider using commercial plastic conditioning products or restorative treatments like hydrogen peroxide to mitigate the effects of sun exposure. Remembering to maintain your plastic items will help extend their lifespan and preserve their functionality and appearance.

Use plastic additives
Plastics are prone to UV damage, which can cause discoloration, loss of tensile strength, and make them brittle and prone to cracking. However, you can increase the UV resistance of plastics by adding UV-resistant additives or caps to protect the base polymer.
There are three main types of UV-resistant additives: blockers, absorbers, and stabilizers. Blockers coat plastics with a protective layer, keeping them safe from UV radiation. Carbon black is a common and effective blocker for outdoor applications, blocking UV rays at a rate of about 2%. Titanium dioxide is another effective blocking solution. Absorbers are usually organic compounds designed to absorb UV light and emit a less harmful wavelength, such as heat, in its place. Benzophenones and benzotriazoles are two common absorbers. Benzotriazoles can be used at low dose rates and are often used in conjunction with acrylic and polycarbonate to maintain transparency. Benzophenones are often combined with polyvinyl chloride (PVC) and polyolefins, as these plastics are not very resistant to UV light.
Stabilizers, such as hindered amine light stabilizers (HALS), prevent a polymer’s bonds from rupturing using chemical techniques. These chemicals dissipate UV radiation, yielding lower UV levels that won’t attack polymer chemical bonds. UV stabilizers play a crucial role in protecting plastics from the harmful effects of UV radiation, extending the lifespan of plastic products, and enabling their application in a wider range of outdoor settings.
UV additives for plastic are mixed into the raw polymer during the manufacturing process to provide the finished product with a UV-blocking quality that prevents or significantly stalls degradation. These additives are also known as UV absorbers and stabilizers and are chemically formulated to absorb the high energy of ultraviolet light and protect the plastic product from exposure to this energy.

Opt for more resistant types of plastic
Opting for more resistant types of plastic is a great way to protect your plastic items from sun damage. Some plastics are naturally more resistant to sunlight damage than others. These include acrylic, polycarbonate, and ABS plastics.
When choosing plastic items, look for those that are manufactured with anti-UV chemicals and/or stabilizers. These additives are specially formulated to be added to the plastic during the manufacturing process to improve the plastic's ability to withstand UV and IR radiation. By using these types of plastics, you can reduce the amount of discoloration and fading caused by the sun's rays.
Additionally, you can also look for plastic items that are designed for outdoor use. These items are often made with more resistant types of plastic that can withstand prolonged exposure to sunlight. For example, outdoor furniture made from recycled plastic may be specifically treated to resist sun damage.
If you are unable to find items made from more resistant types of plastic, you can also consider purchasing UV-resistant covers for your plastic items. These covers will help to shield your plastic items from the sun's rays and prevent sun damage.
