Original authentic 3M 94 electronic double-sided adhesive adhesive for adhesive surface treatment for plastic adhesive for adhesive bottom coating
Used to guide the
1, bonding surface preparation
• Clean the bonding surface with a non-shedding cloth dipped in 50% isopropyl alcohol, acetone or toluene.
• Shake the bottle with 3M 94 base glue vigorously before use.
• Use 3M special tool or brush, roller (without fiber falling off), 94 adhesive evenly coated on the bonding surface, the general coating thickness is 2~4u.
3. Drying time
• Drying time generally depends on temperature, humidity, coating thickness.
• Normal drying time: 1 minute to 1 hour
• Optimal drying time: 10 min ~30 min (temperature: 23℃, humidity: 65%)
• Pay attention to the coating surface is absolutely free from contamination
4, double-sided tape bonding
• Apply double-sided tape to the dried coated surface and apply pressure.
Points for attention:
•1, 3M 94 bottom glue is a chemically active substance, so each time to use, only take out the day (8 hours) of the amount, the rest is still sealed and stored.
•2. The operating environment should be well ventilated and kept clean.
- Global Tab
3M 94 adhesive tape bottom coating, high adhesion, and resistance to high temperature, with double-sided tape used together, can play a very good bonding effect, widely used in construction, automotive and other industries, such as building window screen magnetic strip and window frame fixation, car mirror paste, etc
Product details: Model 94# Brand 3m Bonding Material Type Glass, electronic components, Plastics, rubber, metal, other materials, ceramic shelf life 12(months) 3M94# bottom coating 946.3ml(1 gallon)/ tank 12(4) cans/tank is mainly used for surface pretreatment of some low surface energy materials. Increase the initial stickiness of adhesive tape. Especially suitable for acrylic foam adhesive tape.
Packing: 946.3ml/ 12 cans/box
The adhesive surface shall be cleaned with 50% acetone solution, and the surface shall be thoroughly dried with a brush (without fiber falling off), and the bottom glue shall be evenly coated on the adhesive surface with a coating thickness of 0.05MM. The adhesive tape can be pasted after the bottom glue is dried.
3M 94 bottom glue is a kind of light brown transparent liquid. In order to improve the bonding performance, it is a kind of adhesive coating on the surface of the adhesive before coating. It interacts with water molecules in the air, can produce high adhesive force, and has the ability to resist high temperature, especially when used with 3M acrylic foam tape, can play an excellent bonding effect.
