Hydrophobization – Permanently Protect Surfaces from Water and Moisture

Hydrophobization – Permanently Protect Surfaces from Water and Moisture

​

Hydrophobization is a modern process designed to make surfaces water-repellent and protect them effectively from moisture penetration. At SurA Chemicals, a family-owned business since 1998, we develop innovative hydrophobizing agents, additives, and reactive additives that make materials more durable and resilient.

Our products are versatile – from hydrophobizing plastic surfaces to glass, metal, and applications in the automotive, electronics, and household industries.

​

Properties and Benefits of Hydrophobization

  • Reliable protection against water and moisture

  • Creates a barrier against liquid penetration

  • Improves corrosion resistance and durability

  • Especially suitable for hydrophobizing plastic surfaces

  • Easy application by spraying, dipping, or mixing into paints and adhesives

​

With our hydrophobizing additives, existing coatings can also be optimized for longer life and improved functionality.
