HPHT refines backing coat formulations to boost peel strength and thermal bonding stability for high-elongation ACP production.

Targeting the specialized needs of aluminum composite panel (ACP) producers, Zhengzhou HPHT Industrial Co., Ltd. (HPHT) has upgraded its prepainted substrate coating processes. By optimizing the reverse-side backing coat formulation, this technical refinement specifically addresses the thermal pressing demands of continuous composite panel manufacturing, enhancing bonding performance for high-elongation applications.

The process optimization focuses on the high-temperature lamination stage, where aluminum coils are thermally bonded to polyethylene or mineral core materials. By adjusting the resin cross-linking density and adhesion promoters in the backing coat, HPHT has significantly improved the overall composite peel strength. This structural bonding prevents delamination under thermal expansion and mechanical stress, ensuring that finished ACP sheets maintain structural integrity during cutting, routing, and installation.

By aligning with the rigorous manufacturing standards of global ACP fabricators, this product development positions HPHT as a reliable supply partner for industrial composite panel operations. Providing specialized substrate coils with enhanced bonding performance enables composite manufacturers to streamline production efficiency and secure consistent material quality for large-scale architectural cladding orders.

Looking ahead, we at HPHT are focusing our production capabilities on deep, industry-specific material requirements. Fine-tuning our coil properties for composite integration strengthens our presence in the global building materials market, helping establish a steady, long-term order pipeline with leading panel manufacturers worldwide.
