HARZLAS IML-AR

IML-AR Structure

Harzlas IML-AR is a series of thin-film layers coated on plastic substrates. Typically, it consists of a hard coat layer, AR layers, and an anti-fingerprint layer. The flexible AR coating can withstand most thermoforming processes allowing for use in insert molding. We can customize the layers to meet the requirements for your project.

  • Developed specially for products with 3D surfaces made by insert molding
  • The anti-reflective coating is applied to a sheet before the insert molding process, leading to edge-to-edge coating uniformity

Properties

Optical Properties

Reflectance

Harzlas AR can be optimized from three basic starting points.

  • For projects that need extremely low reflectance, our triple-layer solutions are optimal.
  • If reflected color is an issue, Harzlas AR is available in a more neutral reflected color.
  • For projects that allow for more reflectance, our single-layer option is an optimal starting point.

Transmittance

Harzlas AR also features a high degree of light transmittance throughout the visible light spectrum that extends into the infrared region.
Note: The above data is based on sheets that have the AR treatment on both sides. Single-sided AR is also available.
