Standard Adopt Standard
MF889A-25 silicone stone weather resistant sealing adhesive meets or even surpass the following standard specification:
GB / T 232611 SR25LM
ISO 11600 G, F 25LM
GB / T 22083 G, F 100/50
Application method
Surface cleanup
Remove all impurities and pollutants such as grease, dust, water stains, frost, surface stains, defective sealants, assembly accessories, and protective coatings in the seams and assembly depression.
Non-porous materials such as metals and glass must be used to clean the surface according to the "double cloth wiping". In all cases, the solvent must be wiped with a clean, no descending white cloth. Methods of cleaner or soapy water.
The porous material must be grinded, sawable, rinsed (water, etc.), Russia grinding or synthesizing the above method cleansing the surface, and be sure to ensure that the surface of the glue is thoroughly clean and dry. Materials such as dust and loose particles should be blown out with a compressed air without oil, and use a vacuum cleaner.
Using the undercoat
It is necessary to determine whether undercoat is required by the adhesive test. If the test is determined by the test, the bottom coated to a non-detaching daily cloth is applied to the surface of the sewing to the thin layer, and it is air dry in time.
Shield
The part of the seam is to be shaded to ensure that the work line pump element main adhesive is said, and the shielding tape is not allowed to contact the cleaning surface that will glue. After the glue is formed, it must be trimmed immediately before the sealing gel has not been concluded.
After the shielding tape should be removed immediately.
liner material
Open-hole polyurethane foam rod, closed porosity polyethylene and unsettless polyethylene
The material is recommended by the material. For shallow seams, it is recommended to use a polyethylene tape to prevent three-sided bonding.
Glue method
Install the appropriate pad material, bond the spacer or tape as required.
The MF889A-25 silicone stone weather resistant seal is continuously squeezed and filled with the seam, and the sealing adhesive is compacted in the gasket material and the surface of the seam in the surface of the sealing glue surface. It is recommended to use a convex tool to trim the surface to be concave, and soap or water can be used as a helper material when trimming.
After the trimming, the shield tape was torn off immediately.
Uncorrified silicone sealants should be careful not to splash into the unbelrable surface, such as polished granite or other natural stone, because these unsucked silicone sealants cannot be completely removed with organic or chlorinated solvents, so These surfaces must be obscured, or be careful when geling to prevent sealing gums from being in contact with these surfaces, once uncured sealants come into contact with these surfaces, it will leave a film on the surface, which may affect Beautiful view of the surface of the substrate.
Operational precautions
If you accidentally enter your eyes, you should rinse it immediately.
Do not touch the skin for a long time, avoid children's contact
Unpairing food, drug or cosmetics
Before using the adhesion test and refer to the technical information and safety data sheet of this company, learn about the safety use, harm of the product. If the security matters not involved in this product, please follow the requirements of JGJ102.
Storage and validity
The packed products can be stored in a cool, ventilated, dry, and use it before the "validity period" of the product packaging.
Packaging
Soft package: 592ml each, 20 per box
Use restrictions
This product is not allowed to be used as a structural adhesive, and is not tested or stated as suitable for medical or medicinal.
This product is not suitable for:
The interface in the groundwater or excessive friction is immersed in the water.
It is possible to seep over the oil, plasticizer, solvent surface, or part of the vulcanized rubber gasket or tape
Frost or moist surface
Fully contact with the air in the air during solidification (sealed adhesive needs moisture)
Sealed glue surface paint application (general paint can't adhere to the surface of silica gel)
Direct contact with food or other food grade surface applications
Bonding the cement, the concrete substrate must be completely dried and maintained after 7 days, otherwise it will affect the bonding performance.
Technical Services
Provide complete product technical information.
Adhesive test, compatibility test.
The company's laboratory can provide contaminative testing for customers, customers can maze (or other forms) in the engineering, and the company's laboratory will conduct pollution tests and issued a written test report.
Glue injection method
Install appropriate gasket materials, adhesive spacers or tape as required.
Continuously squeeze the MF889A-25 silicone stone weathering sealant into and fill the joints. When the sealant surface is not yet skinned, press the sealant into the gasket material and the joint surface with appropriate strength. It is recommended to use convex tools to trim the rubber surface into a concave shape. Do not use soap or water as auxiliary materials for trimming.
After finishing the dressing, remove the masking tape immediately.
Be careful not to splash the uncured silicone sealant on non-abrasive surfaces, such as polished granite or other natural stones, because these wet silicone sealants cannot be completely removed with organic or chlorinated solvents. Therefore, these surfaces must be masked, or extra care must be taken when applying glue to prevent the sealant from contacting these surfaces, once the uncured sealant comes in contact with
These surfaces, it will leave a layer of film on the surface, which may affect the appearance of the substrate surface.

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.
