Usage
Surface cleaning: To ensure good adhesion of structural sealant, the surface of the adhered material must be clean, dry, and free of dirt. To prevent sealant from contaminating the joint area during construction, protective tape must be used for protection. After construction is completed, it should be removed.
 & nbsp;& nbsp;& nbsp; Cleaning process:
 & nbsp;& nbsp;& nbsp; Clean and lint free white cloth must be used, and solvents such as anhydrous ethanol, acetone, xylene, etc. can be used; Double cloth wiping method:
 & nbsp;& nbsp;& nbsp; 1. Wipe the adhered area with a clean, lint free white cloth soaked in solvent;
 & nbsp;& nbsp;& nbsp; 2. Immediately wipe the solvent off the surface with a second dry, clean, lint free white cloth before it evaporates;
 & nbsp;& nbsp;& nbsp; 3. The cleaned area must be constructed within 1 hour, otherwise it will be cleaned again;
 & nbsp;& nbsp;& nbsp; 4. Open flames are strictly prohibited in areas where solvents are used, and good ventilation should be maintained.
 & nbsp;& nbsp;& nbsp; Mixing process: R881 should be mixed in a closed mixing and gluing machine system, and the mass ratio of components A and B is A: B=11~14: 1. Users can adjust the curing speed by changing the mixing ratio according to their actual needs.
Limitations
R881 should not be used in the following situations:
All materials that may leak oil stains, plasticizers, and solvents
O vulcanized or semi vulcanized rubber;
The interface on the ground that bears the structural strength
O places subjected to excessive friction and physical damage
Frost or damp surfaces
precautions
Please conduct a bonding test and refer to our company's technical documentation before use.
The O B component can react with water in the air and should not be exposed to air for a long time.
If the O B component is stratified, it is normal to stir it evenly before use.
If accidentally entering the eyes during use, rinse immediately with water.
Do not come into prolonged contact with the skin and avoid contact with children.
Do not contaminate food, drugs, etc.
