Acoustic Spray Coating

This product is a water-based sprayable soundproofing material made from special polymer damping materials, composite acoustic fillers, and functional additives. Designed for professional spraying equipment, it forms a dense, seamless soundproof coating through high-pressure spraying, efficiently absorbing sound wave energy and suppressing structural vibration, providing a fast and effective noise reduction solution.

Product Features

Title	Content
Efficient Application	Professional spray coating provides extremely high construction efficiency, especially suitable for large areas and complex structures.
Excellent Sound Insulation	Outstanding isolation of mid- and low-frequency noise (equipment vibration, traffic noise).
Seamless Sealing	Spraying forms an integrated coating with no seams, perfectly covering irregular surfaces.
Damping & Vibration Reduction	High-density properties effectively suppress vibration and resonance noise of substrates such as steel plates and walls.
Eco-Friendly & Flame Retardant	Water-based, non-toxic, odorless, and provides good flame-retardant performance.

Performance Standard

Title	Content
Standard	GB/T 20247-2006 Acoustics – Measurement of Sound Absorption in a Reverberation Room
Fire Rating	GB 8624-2012 Classification of Burning Performance of Building Materials B1 Grade
VOC Limit	GB 18582-2020 Limit of Harmful Substances in Wall Coatings for Buildings

Scope of Application

Title	Content
Application	Suitable for sound insulation and noise reduction in residential complexes, villas, multi-story apartments, commercial CBDs, training centers (dance, music, taekwondo, etc.), and live-streaming studios; ideal for large metal roofs, floors, and other vibration-prone substrates.

Construction Process

Title	Content
Substrate Preparation	Ensure substrate is firm, free of oil and loose particles. Metal surfaces must be rust-free.
Equipment Preparation	Use dedicated soundproof coating spraying equipment and adjust according to requirements.
Material Preparation	Single-component product, stir evenly before application.
Spray Application	Spray evenly by professionals to the designed thickness (usually 3–5 mm) in one pass.
Curing	Surface dry in approx. 1–2 hours; fully cured in 24–72 hours depending on temperature and humidity.

Product Specifications

Transport & Storage

Title	Content
Transport	Protect from sunlight, rain, and freezing during transportation.
Storage	Store in a cool, dry place at 5℃–35℃, avoid long-term high temperature. Shelf life: 12 months unopened.

Precautions

Title	Content
Construction Environment	Ambient temperature ≥5℃, relative humidity ≤85%, maintain good ventilation.
Effect Guarantee	Soundproofing performance is directly related to final dry film thickness; ensure design thickness is achieved.
Subsequent Decoration	Surface is rough and usually serves as a base layer; wait at least 48 hours before applying putty or topcoat.
Personal Protection	Wear gloves and a mask during application. In case of eye contact, rinse with plenty of water and seek medical attention.
