Types of sealants for headlights

• Silicone sealants. Thanks to them, you can make a plastic strong gasket that can replace the old sealing seam. When the composition is finally hardened, it becomes like soft thermoplastic rubber. The main advantages of this mixture are the ease of use and resistance to temperature drops. The minus is considered that silicone is not resistant to gasoline, oil and coolant.
• Polyurethane sealants. These sealants are characterized by high adhesion with any surface and moisture resistance. Motorists and car mechanics notice the reliability of such a sealant and good service life. An important condition for using this sealant is not to use the composition to seal the moving parts.
• Anaerobic are characterized by the fact that they do not freeze in the open air. For this reason, you may not be afraid to dirty something, because the hardening process is started only after the materials of the materials are closely contacted. Such sealants may not lose their main qualities in the temperature range from -50 to +100 degrees Celsius.
• The sealants are heat -resistant. This composition is characterized by resistance to high -frequency fluctuations and moderate loads. Can keep a temperature up to 380 ° C without loss of basic qualities. This sealant is produced in the form of a pasta, spray spray and powder.
