  1. ONE - POT RTV SEALANT EKP-102


     Description:
     The silicone sealant EKP-102 is a one-pot composition formulated from silicone low-molecular rubber, extender, and curing agent.
     The complete curing time of EKP-102 makes up 72 hours. The cured sealant forms a water -and oil resistant rubbery film which swells and fails in benzine.
     The sealant EKP-102 is produced in 3 grades:
  Grade A - fluid
  Grade B - viscous-flow
  Grade E - high viscous, with high dielectric properties

Applications:

  • The sealants EKP-102 have been designed to hermetically seal and glue together details made of steel, aluminium, siloxane elastomers, and fiberglass plastics as well as devices and appliances which operate in water, steam, and natural gas at 60 ºC to +150 ºC permanently, and at +250 ºC in the short run
  • The EKP-102 Grade A and E is used in the production of electric and electronic devices to seal surfaces of appliances and resistors, to glue together and fix details, to seal cable leads-in, antenna coats, tube heaters
  • The EKP-102 Grade B and E is used in machinery and motor car construction to seal control devices and threaded connections, to fix head-lights , and as gasket seals.
  • The EKP-102 Grade B is used in construction engineering to close joints on vertical and horizontal surfaces, to assemble and repair hygiene equipment, to seal pipe lines, sanitary wares, structural glass, glass-to-glass / glass-to-metal/ metal-to-metal blocks.
  • All grades of the EKP-102 can be used to glue silicate-based materials, articles made of metal, fiberglass plastics, and siloxane elastomers.
Shelf life: 12 Months


  2. ONE - POT RTV SEALANT EKP-104


     Description:
     The silicone sealant EKP-104 is a one-pot composition formulated from silicone low-molecular rubber, extender, and curing agent.
     On exposure to moisture the sealant EKP-104 forms silicone elastomer. The latter is resistant to an exposure to temperature over the range 60 to +250ºC without changing its elasticity, high dielectric properties, and weather- and water resistance.
     The time of complete cure of EKP-104 is 72 hrs.
     The sealant EKP-104 is produced in 2 grades

  3. TWO - POT RTV SEALANT EKP-204


     Description:
     The silicone sealant EKP-204 is a mixture of silicone low-molecular rubber, extender, and curing agent. It is sold as a set of two pots with catalyst and the paste KP-204.
     On exposure to moisture the sealant EKP-204 forms silicone elastomer. The latter is resistant to a long-term exposure to temperature over the range 60 to +150ºC as well as short-term exposure to temperature of about 250ºC without changing its elasticity, high dielectric properties, and weather- and water resistance.
     The paste KP-204 cures over a catalyst for 72 hrs at room temperature.
     The sealant EKP-204 is produced in 3 grades
