Silicone adhesive plastic better method
More types of plastic, such as ABS, PA, PP, PPSU, PPU, TPU, PC, PU, PPS, and so on.Silicone material itself is relatively inert, not all plastic can be directly bonded with silicone, so before production, to choose a more suitable plastic can be more smooth production.
The common silicone adhesive plastics (ABS,PA,PC,PPSU,PP) have different temperature-resistant properties.The choice of production process is not the same, so the choice of glue is different.The price of silicone glue is between 20 yuan and 1500 yuan.Silicone and plastic glue.Molding process generally has two kinds: 1. Silicone molding and plastic bonding.2. The unvulcanized silica gel and plastic are formed together in the mold.So today we are going to talk about what glue is used to compare.
One: silicone molding and plastic bonding.There are usually two ways of bonding.
(1) quick drying: the bonding effect can be seen for about 5-6 minutes.
1. First treat the surface of silica gel to be bonded with K770. K770 treating agent is liquid and easy to operate.The silica gel brushed with K770 treatment agent can be dispensed within 12 hours (each treatment agent may be different, please check with the manufacturer)
2. Press the quick-dry adhesive 601 on one side of silicone or plastic (ABS,PA,PC,PPSU,PP) (which side is more convenient) for several seconds.Place it at room temperature for 1 minute to see the bonding effect.
Advantages of silicone sticky plastic quick drying:
1. The adhesive speed is fast, and the dispensing scheme can be used.
2. Environmental protection SGS.
3. Good viscosity, can reach the degree of silicone tear.
4. High and low temperature resistance (-40°-100°)
Silicone sticky plastic quick drying disadvantages:
1. If the silica gel is relatively thin, there may be a slight white and hard bonding place.
But now fast dry glue market also has low albinism.
(2) slow drying: about 12 hours to see the bonding effect.
1. Clean silicone and plastic surfaces with alcohol.Make sure the bonding material is clean.
2. Apply glue, evenly apply kn-300a on the surface of silica gel or plastic (ABS,PA,PC) (which side is more convenient), and press the two materials together.(note: the slow-drying glue is slow to solidify, and if the joint is not fixed, there will be gaps, or if it bounces off, it needs to be fixed for at least half an hour.)
3. The bonding effect can be seen after 12 hours.
Advantages of silicone sticky plastic slow drying:
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. High and low temperature resistance (-40°-130°)
4. Glue dispensing scheme is optional
One: unformed silicone adhesive plastic (PA,PC,PPSU,PP).
1..Cleaning: first clean the plastic (PA,PC,PPSU,PP) with alcohol and let dry.
2. Glue application: evenly apply cl-24s-15 (or soak, brush, etc.) on the surface of plastic (PA,PC,PPSU,PP), bake for 15-20 minutes at 90-130 °.
3. Molding: combine the cooled plastics (PA,PC,PPSU,PP) with the unvulcanized silica gel.
(dipentafulfide silica gel and liquid silica gel are different from the glue used in plastic molding)
