Accessories And Installation Products - Heat Resistant Silicone

Heat-Resistant Silicone is a polysiloxane-based, air-curing, acetate-system, red-colored, heat-resistant sealing material.

Heat Resistant Silicone

Areas of Use

  • In areas exposed to continuously high temperatures.
  • As a liquid gasket to prevent oil leakage in explosion engines.
  • In areas continuously exposed to machine and motor oils, such as motor covers.
  • As an adhesive and insulator in electric heating devices.
  • As a sealing material and vibration absorber in hot air ducts and sheet metal joints.
  • As an insulation material and adhesive to protect electrical and electronic circuits from heat and humidity.

Features

  • Ready-to-use, single-component sealing material.
  • Resistant to temperatures up to 300°C.
  • Light acetate odor disappears after drying.
  • Solvent-free.
  • Maintains its elasticity permanently.
  • Resistant to abrasion.
  • Unaffected by weather conditions approximately 1 hour after application (at +20°C).
  • Cured surfaces do not adhere to other materials.
  • Cannot be painted.

Pre-Application Preparation

  • The surfaces to be applied must be solid, clean, dry, and free from oil and dust.
  • To ensure a smooth filling, tape can be applied to both edges.

Application

  • Before use, the tip of the cartridge should be cut, and the plastic nozzle should be attached.
  • The nozzle tip should be cut according to the width of the application surface, then the cartridge should be inserted into the gun.
  • During application, joints must be filled in one go without leaving any gaps.
  • After applying the silicone to the joints, the surface should be immediately smoothed using a spatula.
  • After application, the masking tape should be removed.
  • Opened packages should be used as quickly as possible.
  • Do not apply in outdoor areas during rainy weather.

Post-Application Cleaning

  • Contaminated areas and used tools should be cleaned within 10 minutes using industrial solvent (white spirit) or alcohol.
  • Once cured, it can only be removed mechanically.

Storage:

  • Must be protected from water, frost, and extreme weather conditions.
  • Should be stored on wooden pallets in a cool, dry, and moisture-free environment between +10°C and +25°C.
  • Opened packages should be used immediately.
  • A maximum of 8 boxes should be stacked on top of each other.
  • If the above storage conditions are met, the maximum shelf life is 1.5 years.

 

Safety Precautions:

  • During application, general construction safety rules and regulations must be followed in accordance with the Safety Data Sheet (SDS), taking Risk (H) and Precautionary (P) statements into consideration.
  • Contains acetic acid: Before curing, if it comes into contact with the eyes, rinse thoroughly with plenty of water.

Consumption:

  • Varies depending on the size of the joint to be applied.
