Product Description

MF889A-25 Silicone Stone Weatherproof Sealant
MF889A-25 silicone stone weathering sealant is a low modulus, one-component elastic sealant. It solidifies after being exposed to moisture in the atmosphere to form an elastic sealant. The product does not contain toxic and harmful substances and is non-polluting to the environment. It can form a good bond with most building materials and provide excellent weatherproof sealing performance. It has a low modulus, high displacement capacity of 100/50 class, strong ability to withstand repeated high and low temperature alternating deformations, and can be widely used in the waterproof sealing of porous materials such as various building exterior walls for residential industrialization and stone curtain walls.


Operational Precautions
If it gets into eyes accidentally, rinse with water immediately
Do not contact with skin for a long time, avoid contact with children
Do not contaminate food, drugs or cosmetics
Before use, please do a bonding test and refer to the company's technical data and safety data sheet to learn about the safe use and hazards of the product. All safety items not involved in this product, please follow the requirements of JGJ 102

Storage and validity period
The packaged product can be stored for 12 months in a cool, ventilated and dry place, and used before the "expiration date" of the product outer package

Package
Flexible packaging: 592ML per strip, 20 strips per box

Use Restriction
This product is not allowed to be used as a structural adhesive, nor has it been tested or stated as suitable for medical or pharmaceutical use.
This product is not suitable for:
Interfaces in groundwater or places subject to excessive friction
Long-term immersion in water
Oil, plasticizer, solvent may ooze on the surface of building materials, or partially vulcanized rubber gasket or tape
On frosty or wet surfaces
Places that are completely inaccessible to air during curing (the sealant needs to be cured by moisture)
Application of paint on the surface of the sealant (generally paint cannot adhere to the surface of silicone)
Direct contact with food or other food-grade surface applications
When bonding cement and concrete substrates, the substrate must be completely dried and cured for 7 days before construction, otherwise the bonding performance will be affected.

Technical Services

  .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).

  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.
