| Use | Silicone rubber glue is a class of silicone rubber and silica gel, silica gel and similar plastic adhesive, rely on contact to be bonded or sealed surface of water molecules or water molecules in the air and curing. Widely used in mobile phone keys, silicone and silicone, silicone and metal, plastic, electroplating components, silicone rubber, ceramic, wood, stone, glass, nylon, leather between the bonding |
silica gel glue according to its different nature, the raw materials are also different, can be divided into room temperature bonding and high temperature bonding, the main component is silicone, cross-linking agent. Silica gel glue is a two-component instantaneous silica gel adhesive composed of agent A and Agent B. It has the characteristics of high performance, high strength, good flexibility, water boiling resistance, salt spray test and so on, and is very suitable for continuous production line operation; silica gel glue through the EU ROHS standard and SGS testing.
according to its chemical properties, silica gel glue can be divided into organic silica gel glue and inorganic silica gel glue.
organic silica gel glue with high and low temperature resistance, electrical insulation, resistance to oxidation stability, weather resistance, flame retardant, hydrophobic, corrosion resistance, non-toxic, tasteless and physiological inert and other excellent characteristics, widely used in aerospace, electrical and electronic, construction, transportation, chemical, textile, food, light industry, medical and other industries.
inorganic silica gel glue has the characteristics of strong adsorption, rapid and effective adsorption of moisture in sealed packages, stable chemical properties, non-toxic and harmless, and is widely used in food, packaging industry.
silicone rubber glue is a type of silicone rubber used for the adhesion of articles, which is cured by contacting water molecules on the surface of the bonded or sealed object or water molecules in the air. Dry cold environment curing speed may be very slow, but the appropriate environment such as 25 degrees Celsius and 65% relative humidity above the case, this type of glue can be dry in 3-30 minutes (touch dry), the general curing time is dry 10-20 minutes. Complete curing takes 24 hours. After curing, the elastomer has the same properties as the silica gel, and the adhesive strength can reach the tensile force of the silica gel itself. It is the best adhesive for the silicone rubber sealing ring and the sun-shaped hollow tube.
mainly used for the adhesion between silicone and silicone, silicone rubber and plastic, metal (such as copper, aluminum, iron, stone, bamboo, etc.), the product has high transparency, good oil resistance, acid and alkali resistance,
Good adhesion, easy to operate, dry glue fast, not white, high strength, high temperature resistance, water resistance and other characteristics.
silica gel glue is a highly active adsorption material, and various types of silica gel glue form different microporous structures due to different manufacturing methods. The chemical composition and physical structure of silica gel glue determine that it has many other similar materials that are difficult to replace: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength and so on.

Note: The above performance data are typical data measured in the laboratory environment with a temperature of 25 ℃ and a humidity of 70%, which are only for reference when used by customers, there is no guarantee that it is all the data that can be achieved in a specific environment. Please ask the customer to test the data when using it.
colloidal viscosity: 8±3
tensile strength (kg/cm2):≥ 120±10
shear strength (kg/cm2):≥ 80±10
curing speed: Table dry 8 minutes
● use dry cotton cloth or sandpaper to remove dust, oil and rust on the surface, and then wipe with acetone or trichloroethylene to clean the subsequent surface, an appropriate amount of agent A is applied to the surface of the silicone rubber to be bonded for about half a minute, and the surface agent A is allowed to volatilize.
● The front cover of the B agent can be unscrewed, and can be used; The bottle mouth is too large, if there is glue in the bottle mouth, wipe the glue with a cloth, and then use the needle or PE dropper, to control the flow of glue, to ensure the use of the effect.
A small drop of the adhesion agent is dropped on the surface to be adhered immediately, and the adhesion is maintained until hardening, and the hardening time varies from several seconds to several minutes. The practical strength can be achieved in about 30 minutes, and a very high strength can be obtained after 24 hours.
● Clean the bottle mouth after using silicone rubber glue, and tighten the lid.
Please store the glue in a cool and dry place after use.● Do not wear woven gloves, HR series of instant dry glue is absorbed by the woven material of the glove will quickly occur polymerization reaction, the reaction will produce high heat, will burn your hands, so please remember, do not wear woven gloves to use.
● If the eyes are not touched carefully, the eyes will be injured due to the hard glue after curing. Do not rub it with your hands, and immediately rinse with plenty of water or hot compress with a warm towel, so that the sweating of the eyelids will be naturally separated, do not force to pull away, serious and emergency treatment; Skin contact with warm soap water immersion, with acetone, HR series gel removal.
● silicone rubber glue is volatile and irritating. Please keep ventilation in the workplace when it is used in large quantities.
● when there is a large amount of leakage, it can be removed after curing with water.
1, long storage period, easy to use, one can not be used up, the next can continue to use, the longer the time after bonding, the better the bonding effect, room temperature 30 degrees or less can be stored for one year.
2. Avoid direct sunlight exposure.
3, available refrigerator refrigeration.
