Liquid sprayable damping and soundproofing slurry
Made with special functional polymers as the base material, combined with pigments and fillers, and processed through special processes. The product utilizes the viscoelasticity of polymers to convert some of the energy generated by mechanical and acoustic vibrations into thermal energy for dissipation through internal friction generated by the movement of molecular chains.
Product features
Water based environmental protection, low VOC.
High damping coefficient, wide temperature range, excellent noise reduction.
High solid content, good thixotropy, high coating thickness for single application.
Automated spraying process.
Resistant to corrosion, rust, and mold.
Promote lightweight design of automobiles.
