A new, fluorine-free, eco-friendly choice! Betely HLD-12516 silicone-based hydrophobic agent—providing reliable waterproof protection.
2025-11-26 10:49
In fields such as electronics and PCB circuit boards, waterproofing performance directly affects the product’s service life and stability.
Betely newly launched silicone‑based hydrophobic agent, HLD‑12516, with its core advantages of high‑efficiency water repellency, environmental friendliness, and non‑toxicity, as well as its outstanding overall performance, has become an ideal alternative to fluorine‑containing hydrophobics, providing reliable protection for a wide range of products.
Product Highlights
HLD-12516 is an organosilicon water-repellent agent whose main component is a modified polysiloxane. Designed with a fluorine-free formulation, it can form a dense nanocoating on the substrate surface via dip‑coating or spray‑coating, delivering multiple functions including waterproofing, dust resistance, moisture protection, and electrical insulation.
Product Technical Data
Performance Parameters
Product Advantages
1. Excellent dual performance: waterproof and breathable: The water contact angle of the formed waterproof film meets the 90–160° application requirements, exhibits excellent breathability, and does not compromise the substrate’s original properties.
2. Environmentally friendly, fluorine-free, and more reliable: It contains no organofluorine compounds, poses no environmental risks, complies with EU standards, and meets the requirements of green manufacturing.
3. Excellent weathering stability: After 96 hours of thermal shock and salt spray testing with no abnormalities, it is capable of operating in complex environments.
4. Strong adhesion at a cost-effective price: The post‑treatment product exhibits a peel strength far exceeding the 500 g standard, while its price is more competitive than that of fluorinated hydrophobic agents.
5. Convenient construction and wide applicability: Ultra-low viscosity and exceptional leveling; dries naturally at room temperature, with a simple and easy-to‑operate process.
Product Performance Comparison
Compared with fluorine‑containing hydrophobic agents, HLD‑12516 offers differentiated performance advantages that better align with environmental trends and real‑world application needs:
Product Applications
1. Typical application scenarios: PCB circuit boards, electronic component protection, waterproof keyboard membranes, and other applications requiring waterproofing and protective measures.
2. Substrate compatibility range: It can be used on PET and other plastic substrates, as well as various electronic and circuit‑board‑related substrates; after treatment, the surface exhibits a uniform appearance with no visible marks.
Construction and After-Sales Support
● Construction Guide: The dip-coating process is employed, with an immersion time of 5 seconds and a stepwise control of the lifting speed. Prior to application, the substrate surface must be cleaned with a mild detergent.
● Common Problem Solutions: To address issues such as surface watermarks, substrate bite‑in, and low peel strength, we offer tailored process adjustments and remediation solutions.
● Authoritative Testing and Certification: Through relevant testing conducted by CTi, the performance metrics meet industry standards, ensuring reliable quality.
Choose Betely HLD-12516 silicone-based hydrophobic agent to achieve reliable waterproof protection while embracing environmentally friendly manufacturing practices, thereby enhancing product quality.
