Silicone adhesive plastic is a better method
More types of plastic, such as ABS, PA, PP, PPSU, PPU, TPU, PC, PU, PPS, and so on.
Silica gel material itself is relatively inert, and not all plastics can be directly bonded with silica gel, so before production, to choose a more suitable plastic can be more successful production
Common silicone adhesive plastic (ABS,PA,PC,PPSU,PP), due to the different temperature resistance of each material.
The choice of production process is not the same, so the choice of glue is different.
Silicone adhesive plastic glue price between 20 yuan -1500 yuan.
Silicone adhesive plastic glue.
Molding process generally has two: 1. Silicone molding and plastic bonding.
2. Unvulcanized silica gel and plastic are formed together in the mold.
So today let's talk about what kind of glue to use.
There are two general methods of bonding.
(1) quick drying: the adhesive effect can be seen in about 5-6 minutes.
1. First, the surface of silicone to be bonded is treated with K770. K770 primer is liquid and easy to operate.
Silicone coated with K770 primer can be dispensed within 12 hours (there may be differences between each primer, you need to ask the manufacturer for clarification)
2. Press fast dry adhesive 601 on one side of silicone or plastic (ABS,PA,PC,PPSU,PP) (which side is convenient) and press together for several seconds.
If left at room temperature for 1 minute, the adhesive effect can be seen.
Advantages of quick drying of silicone adhesive plastic:
1. Fast bonding speed, dispensing scheme can be used.
2. Environmental protection grade ordinary SGS.
3. Good viscosity, can reach the degree of silicone tear.
4. Resistance to high and low temperature (-40°-100°)
Disadvantages of quick drying of silicone adhesive plastic:
1. If the silicone is relatively thin, there may be a slight whiteness and hardness at the bonding place.
But now there is also a fast dry gum market low albino.
(2) slow drying: about 12 hours to see the bonding effect.
1. Clean silicone and plastic surfaces with alcohol.
Make sure the bonded material is clean.
2. Apply glue, evenly apply kn-300a on the surface of silicone or plastic (ABS,PA,PC) (which side is more convenient), and press the two materials together.
(note: slow dry glue will solidify slowly. If the joint is not fixed, there will be gaps, or if it pops, it should be fixed for at least half an hour.)
3. Leave for 12 hours to see the adhesive effect.
Advantages of slow drying of silicone adhesive plastic:
1. High environmental protection level.
(FDA, medical grade, REACH)
2. The glue is soft after curing, and the hardness of the glue is 30°
3. Resistance to high and low temperature (-40°-130°)
4. Dispensing scheme is optional
I. unformed silicone adhesive plastic (PA,PC,PPSU,PP).
1..Cleaning: first, clean the plastic (PA,PC,PPSU,PP) with alcohol and let dry.
2. Apply glue: apply cl-24s-15 evenly (or soak, brush, etc.) on the surface of plastic (PA,PC,PPSU,PP) and bake for 15-20 minutes at 90-130 °.
3. Molding: the cooled plastic (PA,PC,PPSU,PP) and unvulcanized silica gel are integrated into the molding.
(silicone and liquid silicone are different from the glue used for plastic forming)
