NEW 'SUPER PENETRATING' POROSITY SEALANT ISL-10C for metal castings



  • Apply ISL-10C sealant directly to porosity by brush or spray.
  • ISL-10C naturally penetrates (see video).
  • Sealant cures inside pores at room temperature.
  • Castings can be leak tested after 30 minutes.

Supplied to OEM's and restorers of classic vehicles to seal leaking engines, gearboxes etc.

  • Surface residue can be wiped away.
  • Not hazardous and solvent free.
  • Single part sealant, no mixing.
  • Excellent temperature and chemical resistance.

Birmingham University Impregnation Sealant Test Report (extract):


“In order to be an effective sealant in metal castings the samples must display good wettability, in the form of a low contact angle, and have a low surface tension to enable penetration into the cracks. From the samples tested, which included both thermal and anaerobic curing impregnation sealants, ISL-10C was shown to be the most promising with the lowest contact angle, fastest flow rate and lowest surface tension.”

High surface wetting of 10C compared to a standard vacuum impregnation sealant

Photo shows the high surface wetting of 10C compared to a standard vacuum impregnation sealant. The very low surface tension of 10C spreads 4 x that of the vacuum impregnation sealant (from the same initial droplet size and after 2 minutes on an aluminium plate)




Sealants

Different viscosities of Porosity Sealant are supplied for sealing micro and macro porosity in metal castings.

Porosity Sealant Thin
Porosity Sealant Medium
Porosity Sealant Thick

The sealants are single pack (no mixing) and will cure in the metal substrate in less than 30 minutes at room temperature. Excess sealant can be wiped away before curing. In the fully cured state the sealants are resistant to heat, vibration and a wide range of acids, caustics, solvents and hydrocarbons.
