CEKOMASTIK 999

Economical polysulfide sealant for industrial glazing

Uses

CEKOMASTIK 999 is a two-part polysulfide sealant. It acts as both sealing and insulating material for the production of double glass units because of its high adhesion feature to glass and aluminium surfaces.

Benefits

  • Two part sealant
  • High adhesion to glass and aluminium surfaces
  • Very good insulation (no transmission of vapour inside the double glass unit)
  • Resistant against aging, UV lights, wear and tear.
  • Resistant against weather conditions after 24 hours from the application.

Application

APPLICATION
Application surfaces must be dry and free from oil and dust.
Weight Ratio of Application: 100 g Part A for 10 g Part B are to be mixed until reaching a homogeneous mixture.
 
PLEASE NOTE
Before mixing, it should be checked carefully that Part  A and B have the SAME BATCH NUMBER.
- For application with small volumes, a pump-gun and a spatula can be used.
- Use dosage adjustable machines for reaching a good mixing level for high volume applications.
- Apply mixture to fill the gap between double glass and aluminium bar.
