Blackout Performance and Coating Structure Design

Blackout efficiency in curtains depends on more than pigment loading. The structure of the foam back coating, supported by the acrylic binder, plays a decisive role in light-blocking performance.

A well-designed acrylic binder supports uniform dispersion of titanium dioxide and other fillers. This uniformity prevents light leakage through thin or uneven areas. Foam structure further enhances light scattering, increasing blackout efficiency without excessive coating weight.

Binder flexibility allows thicker coatings to be applied without cracking. This is particularly important for high-performance blackout curtains used in hospitality or commercial settings.

In multilayer designs, acrylic binders compatible with TPU films offer additional design flexibility. Strong interlayer adhesion ensures composite structures remain intact during use.

Understanding the relationship between binder chemistry, foam structure, and optical performance enables more efficient coating designs. Acrylic binders tailored for curtain applications provide a reliable foundation for such optimization.
