Direction For Use
● OSi HIOSil MS316 polymer can quickly dissolve in common organic solvents but is almost insoluble in water. Therefore, most of the raw materials in the formulation system are oil-soluble substances.
● The curing mechanism of the polymer involves the reaction of alkoxy silane groups at both ends of the polyether with water under catalytic conditions. This reaction hydrolyzes the silanol groups, and these silanol groups crosslink under catalytic conditions to form siloxane bonds, ultimately creating a network structure.
● Other additives and fillers in the formulation need to be pre-dried, and the mixing process should be carried out under the protection of an inert, dry gas.
● For more technical support, please feel free to consult with our technical engineers.
Cleaning
Uncured resin can be cleaned using common solvents such as ethanol. Once cured, it can only be removed through mechanical methods, along with surface cleaning procedures.
Storage &Transportation
● Transportation: Moisture-proof, rain-proof, sun-proof, high temperature-proof, keep away from heat sources, handle with care, no extrusion and collision.
● Storage: Sealed and stored in a low-temperature, dry place, the recommended storage temperature is 5~25°C, humidity ≤50%RH. Keep away from children. Avoid contact with skin and eyes.
● For skin contact, remove the sealant with a cloth, and wash the skin thoroughly with soap and water.
● For eye contact, hold eyelids apart and flush thoroughly with water, contact a physician. Please refer to the Material Safety Data Manual (MSDS) for details.
