Automotive body sealants provide critical sealing, soundproofing, waterproofing, and corrosion protection for vehicle interiors and exteriors, essential for engineering projects and fleet maintenance.
1. Types of Automotive Body Sealants and Their Applications
(1) Silicone sealant: It has good high-temperature resistance and aging resistance, suitable for sealing parts such as car gaskets, especially rtv silicone sealant, which is often used for sealing car engine parts. RTV silicone gasket sealant is not only resistant to high temperatures, but also resistant to corrosion and can withstand high pressure and strong vibration. It has good fluidity and is more suitable for filling various irregular gaps and surfaces.
(2) Polyurethane sealant: Widely used in car body metal bonding and windshiled sealing. After curing, it provides a permanent elastic bond to fasten materials with the framework of the car. It’s water-proof, age-resistance, and good bonding performance. Tengyu TP702 urethane windscreen sealant and TP703 automotive polyurethane sealant is best seling for car sealing.
(3) MS sealant: It does not shrink after curing, keeping the original sealant shape. Good adhesion to various substrates, suitable for carbon steel, stainless steel, aluminum, glass, paint layer, etc. TM510 MS container sealant is suitable for container, board room, van, and bus elastic sealing use.
2. Key Considerations for Selecting Automotive Body Sealants
(1) Requirements for use: For example, windshields and car windows have high requirements for waterproof and anti-aging properties, so we should choose UV-resistant polyurethane sealants, while parts such as engines require stronger shock resistance and high-temperature resistance, so we should choose rtv silicone gasket maker.
(2) Environmental and climatic factors
(3) Elasticity and adhesion of sealants
