Polyamide (polyamide; PA for short) Polyamide, also called "nylon", is a tough angular translucent or milky white crystalline resin.

Glass fiber (original name in English: glassfiber or fiberglass; GF for short) is an inorganic non-metallic material with excellent performance. It is brittle and has poor wear resistance. It is made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns, which is equivalent to a hair. 1/20-1/5 of that, each bundle of fiber precursors consists of hundreds or even thousands of monofilaments. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and other national economy fields.

PA+GF materials with high glass fiber content have been applied in the field of notebook computers, but for high glass fiber materials, it is very important to improve the adhesion of the paint film to the material.
