Spray Adhesive Manufacturer — Industrial Spray Glue from China

Aerosol vs. Bulk Spray Formats

PACT manufactures spray adhesive in two primary formats, each suited to different production scales and operational requirements.

Aerosol Spray Adhesive

Aerosol spray adhesive is packaged in pressurized cans (450ml, 550ml, 650ml) with integrated spray nozzles. The self-contained format requires no additional equipment — simply shake the can and spray. Coverage ranges from 3-5 m² per 550ml can depending on substrate porosity and coating thickness. Aerosol spray adhesive is ideal for small to medium workshops, field installation work, touch-up operations, and production lines processing fewer than 20-30 units per day. The adjustable nozzle allows operators to switch between web spray pattern (for large, flat surfaces) and concentrated spray (for edges and detail work). Our aerosol cans use CFC-free propellants compliant with international environmental regulations.

Bulk Drum Spray Adhesive

For high-volume production, bulk spray adhesive is supplied in 20-liter drums or 200-liter barrels for application through industrial spray gun systems. Bulk format usually lowers the adhesive cost per bonded area compared to aerosol cans, because none of the price goes on the can, valve and propellant, and it provides more consistent application across production runs. Spray guns offer adjustable pressure, fan width, and flow rate controls for precise adhesive deposition. Bulk spray adhesive is the standard format for mattress factories, sofa production lines, and automotive trim shops processing hundreds of units daily.

Aerosol, Canister or Pump System: Choosing by Volume

Decide on cost per bonded square metre at the coat weight your product needs, plus waste, cleaning and downtime — not on price per litre. A bulk grade is also not simply the aerosol without the can: the two are formulated for different spraying conditions, so trial the format you will actually run.

Water-Based Bulk Spray Systems

Our listed aerosol and bulk spray adhesives are solvent-borne. Water-based foam and upholstery adhesives are sprayed from bulk systems — often two-component, with an activator that makes them grab at once — and need wetted parts that suit water, protection from freezing and more drying time. See water-based foam and upholstery adhesives for what to check before switching a line.

Key Application Areas

Spray adhesive excels in applications requiring fast, uniform coverage over large surface areas and bonding of flexible or porous materials. The primary industrial applications include:

• —Upholstery and sofa manufacturing: Bonding foam cushions to frames, attaching fabric or leather covers to foam padding, and laminating multiple foam layers. The spray format avoids saturating foam with excess adhesive, which would create hard spots in the finished product.
• —Foam bonding and insulation: Laminating foam sheets, bonding insulation panels to walls and ceilings, assembling foam packaging, and installing acoustic panels. Foam-safe formulations avoid dissolving polystyrene substrates.
• —Automotive headliner and interior trim: Installing headliner fabric to roof substrates, bonding carpet to floor pans, and attaching door panel fabric. Automotive-grade spray adhesive must withstand interior temperatures exceeding 80°C in tropical markets.
• —Mattress production: Laminating comfort foam layers, bonding quilted covers to foam cores, and edge tape application. Spray adhesive enables fast assembly without rigid bond lines that affect mattress comfort.
• —Embroidery and textile: Temporarily securing fabric to hoops and backing material during machine embroidery. Repositionable spray adhesive holds fabric in place during stitching and releases cleanly afterward.

Is Spray Adhesive Low VOC? Aerosol and Bulk Are Regulated Differently

It depends on the format, because the two formats fall under different rules. An aerosol spray adhesive in a non-refillable can is outside the VOC limits of California's SCAQMD Rule 1168; its VOC content is regulated under the California Air Resources Board consumer products regulation instead. The same kind of adhesive applied in bulk through a spray gun is inside Rule 1168, where foam bonding falls under the plastic foams category at 50 g/L less water and exempt compounds.

Our listed aerosol grades are solvent-borne. Where a factory or a customer specification limits solvent at the spray station, the usual route is a water-based dispersion sprayed in bulk, which changes the gun, the drying time and the glue-line feel as well as the adhesive. For the limits themselves see VOC limits by market, and for the other product lines low VOC adhesives by product line.

PACT Spray Adhesive Production

Our Guangzhou production facility includes a dedicated aerosol filling line with capacity exceeding 50,000 cans per day, alongside bulk adhesive blending and filling equipment for drum formats.
