PP (polypropylene) adhesive treatment agent, primer, adhesion promoter, 3M94 substitute

Primer is a product used to treat the adhesive surface, speed up the bonding speed of the tape and improve the adhesive strength of the tape. It is used for surface treatment of materials that are difficult to bond.
The primer is a light brown transparent liquid that improves the performance of the glue. It interacts with water molecules in the air to improve the adhesion and has the ability to resist high temperatures (especially when used together with acrylic foam tape, it can Greatly improve the bonding effect)
How to use primer
Use a fiber-free cloth dipped in isopropyl alcohol, propylene or toluene to lightly bond the surface
Before use Shake the jar containing the primer vigorously
, use a special tool or a roller without fiber shedding to evenly apply the primer on the bonding surface (the thickness should be to)
, and ensure that the coating surface is not affected by Contamination, wait for it to dry (the normal time is to hours, the optimal drying time is to minutes)
, stick the double-sided tape to the surface of the dried primer (a certain amount of pressure is required)
Primer packaging
Quart/can/box
Gallon/can/box
Precautions for primer
Primer is a chemically active substance. Each time you use it, you only need to take out the amount you need for the day, and the rest still needs to be sealed and stored
. The operating environment should be well ventilated and kept clean
