    Product detailed description

    Loctite SI 5398 (original name Loctite 5398, IDH 2063271) is a one-component red acetoxy silicone, specially designed for industrial applications requiring high temperature resistance up to 300 °C. This flowable silicone is ideal for sealing and bonding in environments where components are exposed to extreme temperatures, such as in heating, industrial furnaces, domestic electrical appliances and heating equipment. A surface skin is formed within 8 minutes after application, facilitating rapid use.

    Applications: Loctite SI 539 is used in industrial applications and furnaces. Its high temperature resistance makes it ideal for bonding and sealing heating elements and equipment that are exposed to high temperatures.

    Typical properties: After curing, it forms a strong but flexible material that protects components from high temperatures and provides mechanical resistance. After 14 days of curing, the shear strength reaches 0.7 N/mm² (after 72 hours at 250 °C, this strength increases to 0.8 N/mm²). use Loctite SF 7063 cleaner. If you are working with plastic materials, Loctite SF 7070 is the ideal choice, which ensures gentle but effective cleaning without damaging the surface.

    Material: For easy and quick removal of old sealant or adhesive residues, apply Loctite SF 7200, which Loctite SF 7200
