1. Substrate Base
Glass Series
Float glass, tempered glass, borosilicate quartz glass; featuring excellent optical performance and rigid stability, they are applied to bathroom anti‑fog mirrors, instrument observation windows and camera windows.
Flexible Thin‑Film Series
Optical‑grade PET polyester film (Estar/HCF film), ultra‑thin and highly light‑transmissive, with temperature resistance ≤130℃. Flexible and bendable, it serves as the primary substrate for flexible transparent electrothermal films.
2. Transparent Conductive Heating Layer (Core Heating Material)
ITO (Indium‑Tin Oxide): The mainstream option with balanced light transmittance and conductivity, widely adopted in glass‑based products.
AZO (Aluminum‑doped Zinc Oxide): An indium‑saving solution with cost advantages, suitable for large‑area devices.
Composite dielectric‑metal‑dielectric conductive film: Adopts high light transmittance and low sheet resistance, selected for high‑end optical equipment.
3. Bus Electrode Materials
Silver conductive paste, printed on the edges of conductive films as bus bars to achieve uniform electrical conduction, reduce edge voltage drop and ensure even temperature distribution across the whole surface.
4. Protective Layer Materials
SiO₂ and MgF₂ optical anti‑reflection protective films; they block moisture and oxidation, improve the abrasion resistance of film layers, optimize light transmittance and prevent aging and performance drift of the conductive layer.
5. Bonding Adhesive Backing
High‑performance PSA pressure‑sensitive double‑sided adhesive; available in standard and high‑temperature‑resistant grades for laminating and installation without compromising light transmission. Grades can be selected according to working conditions.
6. Lead‑out Accessories
FPC flexible flat cables, conductive rivets and Teflon‑insulated leads; they realize stable electrical lead‑out and adapt to customers’ assembly structures.
Brief Introduction to Fullchance’s Production Process
Substrate cleaning → magnetron sputtering deposition of transparent conductive layer → optical anti‑reflection film coating → silver paste bus‑electrode printing → high‑temperature curing → die‑cutting forming → assembly of leads and adhesive backing → full inspection of electrical performance and light transmittance → delivery of finished product samples.
Product Applications
Optical instrument windows, security camera windows, bathroom anti‑fog mirrors, vehicle‑mounted lenses, medical‑equipment observation windows, and anti‑condensation for outdoor industrial control display screens.
Customization of dimensions, power and voltage based on customer drawings is supported, and test samples are available.
