Infrared cutoff pigment

What is Infrared Cutoff Pigment?

Infrared cutoff pigment is a functional pigment designed to block or significantly reduce the transmission of infrared radiation. It plays a critical role in controlling heat transfer and improving thermal insulation performance in coated or colored systems.

This type of pigment is often used where both visual appearance and thermal shielding are required.

Working Principle

Infrared cutoff pigments function by absorbing or reflecting infrared wavelengths while maintaining controlled visible light performance. Unlike reflective pigments, cutoff pigments are more focused on blocking IR penetration rather than reflecting it outward.

Key Features

Strong infrared blocking capability
Helps prevent heat penetration through surfaces
Maintains stable visible color performance
Improves thermal insulation efficiency
Suitable for high-performance coating systems

Infrared cutoff pigments are ideal for systems requiring controlled heat management from outside to inside, especially in transparent or semi-transparent applications.

Frequently Asked Questions

Q1: What does infrared cutoff pigment do?
Infrared cutoff pigment blocks or reduces infrared radiation, helping to prevent heat from passing through coated surfaces.

Q2: How is infrared cutoff pigment different from reflective pigment?
Reflective pigments bounce infrared rays away, while cutoff pigments absorb or block them to reduce transmission through materials.

Q3: Where is infrared cutoff pigment commonly used?
It is used in smart glass, solar control films, automotive coatings, and heat-insulating industrial materials.

Q4: Can infrared cutoff pigments be used in transparent coatings?
Yes, they are often used in transparent or semi-transparent systems where heat control is needed without affecting visibility.

Q5: Does it affect visible light transmission?
It is mainly designed to control infrared light, so visible light can still pass through depending on formulation.
