Seam Sealants for Cars: Protection and Durability of the Body
Seam sealants are specialized compounds designed for sealing welded and joint seams in vehicles. They play a crucial role in protecting the car body from moisture, corrosion, dirt, and mechanical damage. Using seam sealants significantly extends the lifespan of body elements, improves sound insulation, and prepares the vehicle for further processing and painting.
At CarPaint.kz, you will find a wide selection of seam sealants suitable for both professional and amateur use. We offer sealants for various areas of the car, including the underbody, doors, trunk, wheel arches, and other body parts.
Advantages of Seam Sealants
- Corrosion protection – prevents moisture and chemicals from penetrating body joints.
- Flexibility and durability – remains elastic after drying, preventing cracks caused by vibrations and temperature changes.
- Excellent adhesion – securely bonds to metal, plastic, fiberglass, and other surfaces.
- Compatible with painting – allows paint to be applied over the sealant without peeling.
- Additional soundproofing – reduces vibrations and noise penetration through body seams.
Types of Seam Sealants
Seam sealants are classified into different types based on their composition and application features:
Polyurethane Seam Sealants
