5 Expert Tips to Shield Marine Hardware from Sun Damage This Summer

Marine hardware often faces the relentless assault of UV light, which can degrade plastics and compromise performance. Yet, with the right choices and care, high‑performance plastics can outlast steel in sunny, salt‑rich environments.

Below are five evidence‑based strategies to keep your marine components resilient and attractive for years of bright weather.

1. Apply a Base Coat

Dark, opaque pigments absorb UV radiation, preventing it from penetrating deeper layers where it can break chemical bonds. Adding a properly formulated base coat is a simple yet highly effective barrier against sun damage.

2. Choose the Right Material

Fluropolymers—such as PTFE, PVDF, HDPE, and PEEK—possess molecular bonds that resist UV degradation. Tests conducted under Florida’s intense sunlight show that hardware made from these materials can retain integrity for 20–30 years.

3. Incorporate UV Stabilizers

UV stabilizers absorb harmful rays and convert them into harmless heat, safeguarding the polymer’s structure. Many high‑performance plastics already contain stabilizers with the same active ingredients found in personal sunscreens.

4. Maintain Purity

Impurities can trap UV energy and create free radicals that accelerate breakdown. Fluropolymers are naturally pure, and Craftech’s ISO 9001:2008 certification ensures that our materials are virtually free of harmful contaminants.

5. Test Under Real Conditions

Environmental factors—salinity, heat, humidity, and local UV intensity—affect long‑term durability. Even indoor components can degrade from fluorescent lighting or high‑UV areas. Comprehensive testing across your specific operating conditions guarantees reliable performance.

While you can’t eliminate UV exposure, you can dramatically reduce its impact. By selecting the right material, applying protective coatings, and conducting rigorous testing, you’ll preserve the look and function of your marine hardware for decades.
