Product Details
Product Description
MF898 silicone weather-resistant sealant RTV, neutral, one-component silicone sealant,Silicone sealant
MF889-25 silicone weather resistant sealing glue is a single component, highly elastic, low modulus (LM) silicone weather resistant sealed adhesive, used in various forms of curtain wall buildings, especially high-rise building curtain walls and structural complex buildings form. It can be easily extruded at most external ambient temperatures, and solidifying silicone sealing gums in which persistent weathering is formed by means of moisture in the air. Due to its displacement capacity, it can provide 25-year quality assurance with the structural adhesive supporting of the construction industry standard JG / T 475 or European standard ETAG 002, which can be used in its displacement capability.

This product is not allowed to be used as a structural glue, nor is it tested or stated as suitable for medical or medicinal.
This product is not suitable for:
1. Place of seams in groundwater or excessive friction
2. Long-term immersion in the water
3. May exude oil, plasticizer, solvent surface, or part of the vulcanized rubber gasket or tape
4. Frost or moist surface
5. When the cure is completely exposed to the air (the sealant needs moisture to curing)
6. Application of sealed glue surface (general paint can not be attached to silica gel surface)
7. Direct contact with food or other food grade surface applications

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 glue gun to paint from the hose and coat it on the surface of the substrate. In order to increase the curing speed and achieve complete curing faster, the product can be sprayed uniformly and appropriately with subsequent connection operations.

Precautions

* After opening, it should be used up within days, otherwise it must be kept tightly sealed.
* Avoid contact with skin and eyes. In case of accidental contact, rinse immediately with plenty of water and consult a doctor ifnecessary; avoid contact with children; do not contaminate food, medicine or cosmetics. Foaming during curing, pay attention to check and clean the spilled glue.
* 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 slowly, and the construction time will be shortened if the temperature and humidity are higher than the recommended upper limit.
