Crackle powder coatings
Thanks to the unique vintage, distressed, and artistic appearance, crackle powder coatings are widely used in metal furniture, lighting fixtures, decorative crafts, toys, appliance housings, automotive and motorcycle parts, architectural hardware, and interior decorations. Their natural crackle texture enhances the visual depth and design appeal of products. Simultaneously, the coating offers advantages such as corrosion resistance, wear resistance, and environmental friendliness. Suitable for various substrates, these coatings provide products with higher decorative value and durable performance. We can provide you with customized crackle powder coatings tailored to your specific requirements, along with complimentary samples for your testing and evaluation.
Crackle powder coatings utilize changes in factors such as the melt viscosity, surface tension, and curing speed of the powder coating during the baking and curing process, which cause the coating surface to shrink, thereby forming the crackle effect. Common methods to achieve cracking include increasing the filler content or reducing the binder content. Fillers with higher oil absorption are typically selected to inhibit the normal flow of the resin during film formation. This prevents the resin from fully encapsulating the pigment and filler particles, or allows only partial encapsulation, leaving gaps between the particles. Without sufficient resin to fill these gaps, a three-dimensional structure with pigment and filler as the framework is ultimately formed, revealing the primer color at the crack locations.
Different base powder systems produce different types of cracks. For instance, to achieve clear, visible cracks over a larger area, resins with lower viscosity should be selected, as this enhances flowability. Within the same system, the pigment and filler content influences the size and shape of the cracks. Generally, as the pigment and filler content increases, the cracks transition from coarse and large to relatively fine.
