BS-2010 General Purpose Sealant

BS-2010 General Purpose Sealant

A one component, versatile, acetic cure silicone sealant formulated for general purpose glazing and sealing applications where long term reliability is required. It will bond to form a durable, flexible, waterproof seal on many common wet area building materials. It is suitable for both indoor and outdoor applications.

Applications
 
Well-suited for general sealing applications such as sheet metal, skylights, ventilators, air-conditioning systems, metal / plastic signs, glass block structures and as a bedding for marine hardware.
 
Directions
 
1. Surfaces must be clean, dry and free of dirt, grease, oil or water.
2. Surfaces should be cleaned with alcohol, M.E.K. or other suitable solvent. Soap or detergent and water treatments are not recommended.
3. For a neat finish, apply masking tape and remove it before sealant skins over.
4. Cut nozzle at 45° angle to desired bead-width and apply to substrate with cartridge gun.
5. Tooling time is 5 minutes, tack free time is 15 minutes.
6. Uncured sealant can be cleaned up with mineral spirits.
7. Use approved backing material for joints over 10mm deep.
 
Clean Up
 
  • Wet sealants can be cleaned up with acetone or mineral spirits.
  • Cured sealants can only be removed mechanically.
 
Joint Design
 
  • The specified sealant bead size should be calculated to comply with the compression and extension capabilities of the sealant in relation to the anticipated joint width due to expansion and contraction.
  • Generally calculation of the width sealant bead should be computed on the basis of a maximum ±20 % movement capability
  • Minimum joint depth should not be less than 6 mm to accommodate movement.
  • Sealant design joint width-to-depth ratio should be 2:1.
 
Coverage
 
Coverage
 
  • The coverage figures shown above are approximate lineal meter run based on 10% wastage assumption. Actual coverage may vary.
  • Calculation formula:
    X / [(Y x Z) x 1.1] = Coverage

    X = volume of cartridge (or sausage) in ml,
    Y = joint width in cm, Z = joint depth in cm,
    1.1 = 10% wastage assumption,
    Coverage = lineal meter run in cm per cartridge (or sausage)
 
Limitation
 
Not recommended for following applications:
  • Substrates that could be corroded by acetic acid released as the sealant cures.
  • Copper or any alloys containing copper.
  • Polyethylene, polypropylene, and polytetrafluoroethylene (Teflon)
  • Traffic areas subject to abrasion.
  • Structural glazing.
  • Substrates such as concrete, marble, quartzite, or natural stone.
  • Neoprene rubber.
 
Caution
 
Product releases acetic acid during application and curing. Keep out of reach of children. Use in well ventilated areas. Safety data sheet available on request. For further health and safety information, consult the latest safety data sheet.
