Polyols for potting adhesive - Introduction
Open Data Unverified Data
Sealing adhesive is a widely used protective material in industries such as electronics, electrical, and automotive. It is mainly used to encapsulate and protect components to improve their environmental resistance, chemical resistance, mechanical impact resistance, and other properties. Polyols, as one of the key raw materials for potting adhesives, are commonly used as components in resin systems such as polyurethane and epoxy resins.
Properties and functions of polyols
1. Structure: Polyols typically contain multiple hydroxyl (- OH) groups, which enable them to react with isocyanates or other reactants in polymerization reactions to form polymers.
2. Reactivity: The number and distribution of hydroxyl groups can affect the properties of the reaction and the performance of the final product. The type and molecular weight of polyols determine the characteristics of the final resin, such as flexibility, hardness, viscosity, etc.
3. Toughening and modification: By selecting different types of polyols, the toughness, brittleness, and elasticity of the sealant can be improved, enhancing the overall performance of the product.
Common types of polyols
1. Polyether polyol: It has good flexibility and water resistance, and is often used in polyurethane sealant.
2. Polyester polyols: relatively hard, with good heat resistance, suitable for applications that require improved mechanical strength and thermal stability.
3. Aliphatic polyols and aromatic polyols: Choose according to application requirements. Aliphatic polyols usually provide good flexibility, while aromatic polyols are more heat-resistant and chemically stable.
application area
-Electronic packaging: used to protect electronic components such as circuit boards and chips from damage caused by moisture, dust, and other environmental factors.
-Automotive industry: applied to the protection of electrical systems, sensors, and other critical components.
-In the field of architecture, there are also many applications in waterproofing, durability coatings, and other areas.
Selection and formula
Choosing the appropriate type and ratio of polyol is the key to developing high-performance potting adhesive. A comprehensive evaluation should be conducted based on the application requirements, performance requirements, and cost considerations of the final product.
