SGR808 Flame-retardant Adhesive is a two-component flame-retardant adhesive used for bonding conveyor belt joints. It cures at room temperature and normal pressure. The bonding area is only half of that of other methods. It can be put into use 20 minutes after bonding and can be used in an environmental condition of -5°C to 80°C. It is especially suitable for use in special fireproof and explosion-proof environments in coal mine roadways.
Main Performance Indicators
- Peel strength (N/2.5cm): ≥80 after 2 hours of curing, ≥140 after 24 hours of curing.
- Shear strength (MPa): ≥2.0 after 20 minutes of curing, ≥3.4 after 24 hours of curing.
- Flame retardancy: Self-extinguishing after leaving the fire source.
- Shelf life: 18 months (stored in a cool and dry place).
Main Uses and Advantages
- It is mainly used for bonding the joints of conveyor belts with canvas, nylon and other material layer cores.
- It has a fast curing speed at room temperature, high strength, corrosion resistance, aging resistance, good flexure resistance, and is difficult to burn when exposed to fire.
- The operation process is simple and the cost is low.
Usage Method
- Mix the SGR808 adhesive and the 450 curing agent evenly. Apply it on the surface of the dry joint in three times. Wait until the solvent evaporates (if it is baked with an infrared lamp, the solvent evaporation can be accelerated). When the adhesive film is not sticky to the touch but has a sticky feeling, it can be bonded.
- When bonding, align the joint, bond it from the front to the back, and use a rubber hammer to push and press it back and forth 2 to 3 times from the middle to the surroundings to expel the air.
- After the joint is bonded, let it stand for 20 minutes and cool down to room temperature. Then the site can be cleaned up and the conveyor belt can run under load. If the curing time is extended, the bonding effect will be better.
Precautions
- This adhesive contains organic solvents and is slightly toxic. When storing and using it, pay attention to preventing poisoning.
- If the adhesive liquid becomes thick, an appropriate amount of diluent can be added for dilution.
- Do not let the adhesive liquid come into contact with water. The surface of the bonded object must be dry, otherwise it will affect the curing effect and bonding strength.
