Unlocking New Potential in Materials: ChangFu® EXC4 Pioneers a New Avenue for High-Performance Applications

Amid growing performance requirements in electronic packaging and high-performance coatings, ChangFu^® EXC4 distinguishes itself through innovative molecular design. This specialized cyclic siloxane offers a unique molecular architecture that provides two fundamental benefits: the ability to form high-density crosslinked networks—enhancing mechanical strength and chemical stability—along with effective suppression of curing shrinkage, thereby reducing dimensional deformation and internal stress.

Product Highlights:

1.      High-Density Crosslinked Network

²  Improves hardness, wear resistance, and chemical corrosion resistance

²  Enhances insulation properties in electronic packaging, effectively blocking moisture and impurities

²  Increases toughness and scratch resistance in coating applications

2.      Reduced Polymerization Shrinkage & Internal Stress

²  Restrains irregular molecular chain contraction during curing

²  Prevents void formation in electronic encapsulation and protects chips from stress damage

²  Promotes strong coating-substrate adhesion, extending service life

3.      Compatible with UV and Thermal Curing Systems

²  Enables rapid UV curing for high-speed production lines

²  Suitable for a wide range of thicknesses and processing conditions

Application Areas:

1.      Electronics: chip bonding, circuit board protection, electronic adhesives

2.      Protective Coatings: metal protection, scratch-resistant surfaces

3.      Plastics & Composites: ideal for 3D printing applications

4.      Fiber Coatings & Nanomaterial Surface Treatment

ChangFu^® EXC4 has become a material of choice for advanced electronic protection and high-performance coating systems. As industries such as electronics and advanced manufacturing continue to evolve, their applications are expected to grow, especially in precision electronic packaging and durable weather-resistant coatings—bringing innovative material solutions to the forefront.
