DONEWELL Neutral Silicone Gasket Maker, Black

SKU: DGT-212

High-temperature DONEWELL® silicone gasket maker for forming and repairing gaskets in engine and transmission oil pans, thermostat housings, water pumps and other vehicle assemblies. Replaces paper, rubber, metal and other conventional gaskets.

The solvent- and acid-free neutral-cure formula is non-corrosive and suitable for sealing electrical connections and sensors. It resists automotive service fluids except gasoline. The thixotropic compound stays in place without running or sagging.

Fills gaps up to 7 mm. Once cured, it withstands temperatures from −50 to +250 °C continuously and up to +330 °C for short periods. One tube produces approximately 8.5–9 m of a 4 mm bead.

Helpful Tips →
  • Apply to clean, dry and degreased surfaces at an ambient temperature of +5 to +40 °C. The gasket maker itself should be at +20 to +25 °C. Apply a continuous, even 2–3 mm bead to one mating surface.
  • Skin-over time: 10–15 minutes. A gasket up to 3 mm thick fully cures in 24 hours at +23 °C and 50% relative humidity.
  • No bolt retightening is required after the gasket maker has cured.
  • Clean uncured material from tools and surfaces with solvent. Remove cured material mechanically.

Use KERRY® KR-969 Gasket and Sealant Remover to remove old gasket residue. Use KERRY® KR-965 Brake Cleaner to clean and degrease the mating surfaces.
