Sealing and LASD applications in paint shops require high quality, performance, and precision. They must prevent long-term corrosion and meet the increasing demands for a car’s aesthetic appearance and passenger comfort. Atlas Copco's paint shop solutions boost productivity, ensure consistent high quality, and are user-friendly.
- Cosmetic sealing
Cosmetic sealing requires high precision and aesthetic quality to meet visual standards. It must ensure a smooth finish and seamless integration with the car's design. We offer various technologies to apply cosmetic beads, with customized nozzles tailored to car design and robot movement.
- Interior seam sealing
Interior seam sealing requires accessibility through window openings and high robot speeds to keep cycle times low. We offer flexible and reliable sealing solutions, ensuring high-quality seals with minimal rework.
- Sound dampening
To reduce noise and increase comfort, liquid-applied sound dampening materials (LASD) are used on floor panels. These materials can be challenging to apply in high volumes and flow rates. Our systems provide effective LASD dispensing tailored to customer requirements and material properties.
- Underbody protection
Underbody protection is crucial for preventing stone chipping and corrosion, especially in high-stress areas like wheelhouses and rocker panels. Our solutions ensure high application quality, handle high flow rates, and support fast robot speeds for efficient manufacturing.

Cosmetic sealing applications
Challenges in cosmetic sealing:
Car designs have complex geometries and surface breaks where tight seals are crucial to prevent corrosion. Areas like doors, trunks, hoods, rear gutters, roof ditches, and rear lights are hard to reach with precision. Atlas Copco’s SCA product line offers various technologies to meet high demands in function, quality, and aesthetics. Customized nozzles tailored to car design and robot movement are provided.
Our solutions for cosmetic sealing applications:
Mini flat stream: A low-pressure application with high precision and accurate material distribution. Ideal for hem flange sealing on doors, it ensures a smooth surface and excellent aesthetic appearance.
Jet stream: Suitable for aesthetically demanding seam sealing areas like trunk lids, roof ditches, and rear lights. It supports high robot speeds and ensures a high-quality finish. The tool’s symmetry simplifies robot programming for complex geometries.
Extrusion: A low-pressure application requiring a short application distance. Special U-shaped nozzles apply beads at trim edges to prevent corrosion, used in high-stress areas like wheel arches. Elastic nozzles compensate for deviations in robot movements and car part tolerances.
Interior seam sealing
Challenges in interior seam sealing:
Accessibility is a major challenge, as areas must be reached through window openings while maintaining high robot speeds to keep cycle times low. Atlas Copco’s SCA product line offers flexible and reliable sealing solutions.
Our application solutions:
Flat stream application: Ideal for interior seam sealing, it processes PVC with high flow rates and low cycle times. The even material distribution ensures high quality and minimal rework. Customizable with various nozzles for flexibility.
E-Swirl application: E-Swirl improves process reliability with its rotational symmetrical pattern, providing even material distribution and sharp contours. It excels in tight radii and hard-to-reach areas, handling complex geometries with precision.
Sound dampening in paint shop
Challenges in sound dampening:
To reduce noise and increase comfort, liquid-applied sound dampening materials (LASD) are used on floor panels. These materials can be challenging to apply in high volumes and flow rates. Robust system components are essential. Atlas Copco's SCA product line offers effective LASD dispensing systems tailored to customer requirements and material properties.
Our application solutions:
Flat Stream applications: Flat stream is a low-pressure application ideal for LASD, using wide slot nozzles for broad beads and even material distribution. It handles high flow rates at short cycle times, allowing precise application where needed and saving material in low-vibration areas.
Multi-orifice application (MOG): MOG is effective for water-based acrylic LASD, applying multiple parallel beads within 75 mm or 150 mm widths. It processes high volumes quickly, with a special bead pattern providing a larger application surface.

Underbody applications
Challenges in underbody applications:
Protection against stone chipping and corrosion is crucial, especially in high-stress areas like wheelhouses and rocker panels. PVC is commonly used for sealing seams and forming protective coats. Atlas Copco’s SCA product line ensures high application quality, handles high flow rates, and supports fast robot speeds.
Our application solutions:
Flat stream for underbody seam sealing: Flat stream protects trim edges against corrosion with moderate pressure and accurate material distribution, allowing high flow rates and low cycle times. It can be adapted to various requirements.
Airless underbody spraying: Airless spraying offers high-pressure protection against humidity and stone chipping, allowing flexible coat thickness, application distance, and speed.
Wide flat stream for underbody coating: Wide flat stream uses customized nozzles for up to 150 mm application width, ensuring repeatable quality with no overspray, preventing contamination and improving appearance.
Rocker panel/anti-chip application: Rocker panels require careful corrosion protection and high aesthetic standards. PVC coats can be applied with flat stream or airless spraying, using special masking tools for sharp contours.
