Film-forming Substances (Resins)

Film-forming substances are the fundamental components of coatings, directly affecting the adhesion, strength, durability, and overall performance of the coating. Different types of resins are suitable for different environments and usage scenarios.

Bisphenol A epoxy resin

Features:

Bisphenol A epoxy resin is a basic epoxy resin made of bisphenol A and epichlorohydrin as the main raw materials, with excellent mechanical properties, electrical insulation and chemical corrosion resistance.

Function:

Used as a base resin to provide strength and chemical stability;

Used in combination with a variety of curing agents to form a high-strength three-dimensional network structure.

Application scenarios:

Coatings: anti-corrosion coatings, floor coatings.

Adhesives: bonding of materials such as metals, ceramics, and glass.

Composite materials: aerospace, automotive parts, wind turbine blades, etc.

Electronic and electrical: potting glue, printed circuit board substrate.

Advantages:

Excellent mechanical properties and high strength after curing.

Excellent electrical insulation.

Strong chemical corrosion resistance.

Combined with curing agents, it can adapt to a variety of process requirements.

Modified bisphenol A epoxy resin

Features:

Modified bisphenol A epoxy resin is modified by adding other ingredients (such as elastomers, nanofillers, flame retardants, etc.) to the basic bisphenol A epoxy resin, and optimized for specific performance requirements.

Function:

Improve toughness, heat resistance, flame retardancy and other characteristics to overcome the shortcomings of basic epoxy resin.

Adapt to specific environments (such as high temperature, humidity, and highly corrosive occasions).

Application scenarios:

High toughness requirements: impact-resistant coatings, flexible adhesives.

High temperature environment: high temperature resistant composite materials, high temperature anti-corrosion coatings.

Flame retardant occasions: building fire retardant coatings, electrical equipment packaging materials.

Special process: used in occasions requiring low viscosity and high transparency, such as optical coatings.

Advantages:

Toughness modification: significantly improve impact strength and crack resistance.

Heat resistance modification: adapt to high temperature environment, excellent thermal stability.

Flame retardant modification: improve fire safety, suitable for high-risk scenarios.

Constructibility optimization: reduce viscosity, improve coating leveling, and easy construction.

Environmentally friendly: Environmental protection requirements (such as low VOC) can be met by adjusting the ingredients.
