What Are Car Body Sealants?
Car body sealants are specialized chemical compounds designed for professional body shop applications, providing permanent bonds and weather sealing for automotive repair and manufacturing. These structural adhesives ensure vehicle integrity through advanced bonding technology.
Hem Flange Sealants
Phirol Hem Flange Adhesive, with its superb stickiness, has become an essential element in auto repair shops. Its standout rheological characteristics lend to its resistance to wash-off, making it a trustworthy option for various uses. Worth mentioning is its role in enhancing the stiffness of hang-on parts and crash durability – critical aspects in car body building, hemming gap control, and structural areas. The two main types of Hem Flange sealants – Epoxy and Rubber-based, each have distinct characteristics that differentiate them. The Epoxy variant is highly praised for its excellent bond with automotive steels, including coated steels and pretreated aluminum. Read More
Structural Adhesive
Phirol Structural Adhesive, a proficient bonding method used in body shops, offers numerous advantages such as enhanced vehicle body rigidity, resistance to corrosion, and a decrease in spot weld points. This technique effectively reduces the weight of the car and manufacturing expenses while amplifying its mechanical performance. These structural adhesives have stood the test of time and have shown remarkable effectiveness on both identical and varied materials used in body shops. They provide exceptional resistance against wash-out, can be employed using standard equipment, pledge reduced warranty expenses, and display outstanding durability over time.
Expandable Mastic Sealants
Phirol Expandable Mastic Sealantsare an economical solution highly sought after in the Automobile Body Shop industry for their efficiency in mitigating metal contact, minimizing vibration, and reduce noise disturbances. These anti-flutter formulasare available in a variety of shapes and sizes and are designed for application on oily metal parts that experience high levels of vibration, such as car doors or roofs. The special characteristic of these sealants is their ability to firmly adhere to oily surfaces while simultaneously resisting wash-off and corrosion. Available ready-to-use in an uncured state, these expandable mastic sealants bind effortlessly to any metallic surface, blossoming under heat to seal gaps between metals. Read More
Spot Weld Sealer
Phirol Spot Weld Sealer serves as a prime component in the automobile body shop industry, acting as an effective adhesive for metallic parts that are to be united via electric spot welding. This unique sealer is favoured due to its minimal electrical resistivity, facilitating easy electro-welding. Once it has undergone curing, it acts as a potent anti-corrosive and noise suppressant material. This heat-curing sealant boasts impressive adhesive properties even on oil surfaces and offers a broad range of curing temperatures. It also features excellent spot weldability, sealing capacities, chemical resistance, and elasticity. Read More

Car Body Sealant - Frequently Asked Questions
Which car body sealant is best for automotive applications?
Professional car body sealants depend on your application. Hem flange sealants for panel joints, structural adhesives for load-bearing connections, spot weld sealers for post-welding, and expandable mastic sealants for cavity sealing.
How long do automotive body sealants last?
Professional car sealants provide extended service life compared to standard products. Automotive seam sealer applications maintain performance for years when properly applied, depending on environmental conditions and application technique.
Are Body Shop sealants compatible with all metals?
Our car body panel sealant range works with steel, aluminum, and mixed metal substrates. Structural adhesives bond effectively to treated and untreated surfaces.
What's the difference between sealants and adhesives?
Car body sealants provide sealing and corrosion protection, while adhesive products focus on structural bonding. Many automobile body shop applications use hybrid formulations that deliver both functions.
Can I apply car body sealants over existing finishes?
Body shop sealants bond to painted, primed, and bare metal substrates. Automotive seam sealer products work over phosphated, e-coated, and painted surfaces when properly prepared.
