®Hydrophobic & Oleophobic Coatings
この技術製品群のECLEARモデル、材料構成、用途、プロセスウィンドウ、検証要件をご確認ください。
材料積層構造の内容.
各層は機能順に示しており、正確な構成はグレードごとに異なります。
- 01Qualified substrate or hardcoat
- 02Optional activation/primer interface
- 03Thin hydrophobic or oleophobic topcoat
Lower surface energy for water beading and easier cleaning.
01A hydrophobic topcoat changes the interaction between the exposed surface and water. Instead of spreading, a droplet forms a higher contact angle and can roll away more readily when gravity, airflow or wiping force is applied.
02Oleophobic and easy-clean performance are related but not identical to water repellency. Oils, fingerprints and cleaning agents have different surface tensions, so each target should be measured with an appropriate liquid, method and durability sequence.
03The topcoat is thin and interface-sensitive. Contamination, incomplete activation, excessive coating mass or incompatibility with a hardcoat, PVD film or ink can reduce adhesion or create optical non-uniformity.

ライン試験前に技術者が確認する質問.
サンプル依頼前に、材料の役割、界面、工程範囲を明確にしてください。
Is contact angle alone enough to select an easy-clean coating?+
No. Contact angle is useful, but roll-off, hysteresis, oil interaction, abrasion durability and compatibility with the underlying stack are also important.
Can the coating be used on both polymer and glass?+
The public platform includes qualified hardcoated or metallized PC and acrylic surfaces, with other polymers and glass evaluated project by project.
Can ECLEAR recommend a grade from an application description alone?+
A first shortlist is possible, but a production recommendation requires the substrate, layer construction, equipment, process sequence, test method and acceptance criteria. ECLEAR normally moves from requirement definition to laboratory matching, samples, line trial and a frozen approved specification.
Are the values shown on this page guaranteed specifications?+
No. Website values and constructions are selection guidance. Guaranteed limits, test conditions, packaging and shelf life are controlled only by the latest ECLEAR-approved TDS, quality agreement and customer qualification record.
