Hard Coatings are advanced protective coatings applied to surfaces to improve their resistance to scratches, abrasion, and wear. These coatings form a hard, durable layer on the substrate, making it resistant to mechanical damage and external elements such as chemicals, UV radiation, and moisture. Key Characteristics of High-Quality Hardcoats For a hardcoat to provide effective protection, it must possess several critical characteristics: Scratch and Abrasion Resistance: The primary function of hardcoats is to protect surfaces from scratches, scuffs, and abrasion during regular use or in harsh environments. Chemical Resistance: Hardcoats provide a barrier against solvents, acids, and other chemicals, ensuring the substrate remains intact and performs well over time. UV and Weather Resistance: Hardcoats designed for outdoor applications should resist UV radiation and weathering to prevent yellowing or degradation when exposed to sunlight.

Barrier coatings for paper are surface coatings applied to the paper surface to provide protection against external elements such as water, oil, gases, and various chemicals. These coatings serve as a barrier, preventing the penetration of these elements into the paper and preserving its integrity. Advantages Improved barrier performance: Barrier coatings provide enhanced protection against moisture, oil, and oxygen, greatly extending the shelf life and freshness of packaged products. Better printability: Barrier coatings have superior printability, enabling more detailed and vibrant printing on paper packaging, thereby improving brand recognition and consumer appeal. Reduced cost: Although the initial development and production costs of barrier coatings are higher than traditional PE lamination, the economies of scale and technological advancements are driving down the costs, making barrier coating for paper a more cost-effective option in the long run.

Chlorinated Polyethylene, often referred to as CPE, is a polymer derived from High- Density Polyethylene (HDPE) through partial chlorination. The introduction of chlorine atoms grants CPE a degree of softness and rubber-like properties. Moreover, it transforms CPE into a polar polymer with polar groups akin to PVC, bolstering compatibility with PVC.

SAN Processing Aid is a super high molecular weight polymer copolymerized from styrene and acrylonitrile,with a molecular weight exceeding 5 million that enhancing PVC's properties,promote PVC plasticization,obviously improve the thermal deformation temperature and surface smoothness of PVC products, and at the same time give PVC products higher surface hardness and rigidity.elevating their overall quality.
