Product Overview

A versatile white expansion foam spray adhesive designed for superior insulation, bonding, and waterproof sealing across industrial and construction applications. Utilizing advanced polyurethane technology with an acetic curing system, this multi-purpose sealant expands to fill gaps, creates durable moisture barriers, and provides excellent thermal and acoustic insulation.

Key Features

• Strong Expansion & Adhesion

• Expands upon application to fill irregular gaps, cracks, and voids thoroughly.

• High adhesion to most construction materials: glass, wood, metal, concrete, and plastics.

• Acetic Curing for Durability

• Forms a robust, flexible seal resistant to weather, moisture, and temperature fluctuations.

• Cures with characteristic acetic reaction, ensuring stable long-term performance.

• Thermal & Acoustic Insulation

• Closed-cell structure reduces heat transfer and minimizes noise penetration.

• Ideal for energy-efficient building envelopes and industrial equipment insulation.

• Waterproof & Weather-Resistant

• Creates an impermeable barrier against water, humidity, and air infiltration.

• Suitable for indoor and outdoor use in extreme conditions.

Applications

• Construction & Renovation

• Sealing gaps around window and door frames.

• Insulating wall cavities, roofs, and piping penetrations.

• Glass & Glazing Systems

• Bonding and insulating glass panes in windows, curtain walls, or partitions.

• Filling expansion joints in structural glazing.

• Waterproofing Projects

• Sealing foundations, balconies, and terraces against moisture.

• Repairing leaks in gutters, vents, and flashings.

• Industrial & DIY Use

• Fixing and insulating HVAC ducts, storage tanks, and containers.

• Craft, model-making, and small repair tasks requiring precision foam application.

Technical Advantages

• Expansion Rate: Up to 2–3 times original volume for full cavity filling.

• Service Temperature: -40°C to 90°C after curing.

• Waterproof & Mold-Resistant: Protects structures from damp and microbial growth.

• Paintable & Sandable: Allows seamless finishing to match décor or surface requirements.

Usage Instructions

1. Shake can vigorously for 30 seconds before use.

2. Apply using a professional foam gun or disposable straw nozzle.

3. Spray into clean, moistened gaps (moisture aids curing).

4. Allow full expansion and curing (approx. 4–6 hours), then trim or shape as needed.

Safety & Compatibility

• Wear gloves and eye protection during application.

• Compatible with most common building substrates; test on plastics and finishes beforehand.

• Acetic odor during curing — ensure adequate ventilation.
