MF3250 Butyl Sealing Tape
MF3250 is a one-component, solvent-free, non-fogging, non-vulcanized, permanent plastic sealing tape. MF3250 maintains its plasticity and airtightness in a wide temperature range, and the surface does not crack or harden. The product exhibits good adhesion performance, medium strength, good high temperature resistance and chemical properties, and maintains plasticity at low temperatures, so it is not easy to become brittle or crushed into pieces. It has passed the EN45545 flame retardant performance test and TB/T3139 " "The limit of harmful substances in interior materials and indoor air of rolling stock" test.
Scope of use
MF3250 sealing tape is mainly used in the transportation field. For sealing points, roof welds (metal, plastic, wood), etc.

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.
