Product Description

Mf840 Two Component Polysulfide Sealant Fbr Insulating Glass
♦ MIXING AND DISPENSING INSTRUCTIONS
SILANDE MF840 has to be mixed homogeneously and air-bubble free in the correct ratio.
SILANDE MF840 should be mixed in a ratio of 10:1 base to curing agent by weight, or equivalent 8.6:1 by volume for optimal properties. At this mix ratio, the sealant typically exhibits a working time of 20-30 mins and allows units to be handled within 6~8 hours. Slight variations in mixing ratio can be tolerated, but these should not exceed 100:6 to 100:12 by weight to ensure minimum properties are obtained.
Mixing Ratio by Wight 100:6 100:8 100:10 100:12
Mixing Ratio by Volume 14.3:1 10.7:1 8.6:1 7.1:1

  .APPLICATION FIELD

  • One component, solvent free, non-fogging, permanently plastic butyl sealant, formulated for primary sealing of insulating glass units.
  • It can keep its plastic and sealing properties in a wide temperature range.
  • Excellent adhesion properties on glass, aluminum alloy, galvanized steel and stainless steel.
  • Minimum moisture vapour and gas permeation.
  • Excellent temperature stability: - 30°C to 80°C.

  ♦ TECHNICAL DATA - TYPICAL PROPERTIES
  MF322 two-component polyurethane corner glue
  Mainly used for bonding and sealing between aluminum alloy corners and profile cavities in aluminum alloy door and window structures; suitable for bonding wooden doors, windows and doors; for processed different materials, such as wood, building materials, ceramics and metals It has good adhesion.
  How to use instructions
  Remove dirt, dust, oil, frost, etc. on the surface of the substrate; place the plastic nozzle on the open bottle mouth and tighten it, and use a dedicated 1:1 double bottle glue gun to inject glue. Uncured glue can be cleaned with special cleaning agents (or other solvents such as alcohol).
  
  Packaging

  

  

  Packaging
  1:1 double plastic bottle packaging: 600 ml per group; 9 groups per carton
  
  Transport transmission
  This product is non-hazardous and can be transported by train, car, ship and plane
  
  Store
  Can be stored for 6 months in a cool, ventilated and dry place.
  
  Precautions and precautions
  The initial 20g of mixed glue may be insufficiently mixed and is not recommended.
  The glue mixed at room temperature should be used during the application period.
  Avoid contact with skin and eyes. If inadvertently, rinse immediately with plenty of water and consult a doctor if necessary;
  avoid contact with children; do not contaminate food, medicine or cosmetics.
  The heavy workpiece to be bonded should be avoided to move before it is completely cured, and measures should be taken to fix it when it is necessary to move.
  Recommended use conditions: temperature 15 ~ 35C, relative humidity 40% ~ 80%; if the temperature and humidity are lower than the recommended lower limit, the horn glue will cure more slowly, and if it is higher than the recommended upper limit, the construction time will be shortened.

  

  

  

.CURING
When mixing SILANDE MF840Abase + SILANDE MF840 B catalyst at approximately a 10:1 weight ratio, the material will become tack-free at about 25-35 mins under ambient conditions of at 23°C, 50% R.H. After 3 days IGU can be transport to project, Development of full properties requires full evaporation of cure by-products and will normally be achieved within 5 days (can be start for installation). Full properties will take additional time in colder climates.
It is important when selecting components for a project that adhesion and compatibility tests are carried out, and found to be successful, before the project starts.
.SHELF LIFE AND STORAGE
12 months from the date of production below 30°C.
MF-840 two-component polysulfide insulating glass special sealant series (hereinafter referred to as MF-840 series) is a solvent-free, two-component, room temperature curing elastic sealant, suitable for glass, aluminum alloy, galvanized steel, and other materials Has excellent bonding properties.
MF840 series sealant is composed of two components A and B. The A component (base paste) is a white uniform and delicate paste, and the B component (vulcanized paste) is a black uniform and delicate paste. Use ratio, A component: B component = (mass ratio) 100: (6-12), the best use ratio is 100:10.
MF840 series sealant is mainly used to make insulating glass.
Insulating glass: two or more pieces of glass are effectively supported and evenly separated and bonded and sealed around the periphery, so that a dry gas space is formed between the glass layers.
MF840 series sealant can be used with butyl sealant: butyl is the first seal and polysulfide is the second seal (outer seal); it can also be used to seal single-channel insulating glass.
