Rubber to metal bonding agent 829GB is a multifunctional adhesive suitable for bonding various elastomer compounds to substrates during the vulcanization process as a cover coat adhesive. It is formulated without heavy metals and composed of a mixture of polymers, organic compounds and mineral fillers dissolved or dispersed in an organic solvent system.
This adhesive system will bond compounds based on natural rubber (NR), polyisoprene (IR), styrene-butadiene (SBR), polybutadiene (BR), polychloroprene (CR) and nitrile (NBR), butyl (IIR) and EPDM polymers to metal.
Surface treatment agent used for bonding rubber to metal as a cover coat.
Used as a cover coat adhesive and in combination with a primer adhesive, suitable for the following types of rubber:
Components: polymers, organic compounds, inorganic fillers and organic solvents.
| Property | Value |
|---|---|
| Appearance | Black Liquid |
| Viscosity, cps @ 25°C (77°F) Brookfield LVT Spindle 2, 60 rpm | 150-600 |
| Solids Content by Weight, % | 24-26 |
| Flash Point (Seta), °C | 25 |
| Solvents | Xylene/Dimethyl carbonate |
During the storage process of 829GB, some sediment will settle at the bottom of the container. Before painting, it must be thoroughly stirred to achieve uniform mixing before use. If the painting process is long, stir at high speed for 5-10 minutes every 2 hours.
This product can also be diluted with diluents according to actual operational needs. It is recommended to dilute according to the amount used. Diluted products should not be stored for a long time. Brush coating method: no dilution is required. Roller coating method: no dilution is required. Dip: 100 parts of 829GB and 10-30 parts of diluent. Spray method: 100 parts of 829GB and 20-40 parts of diluent.
This product can be coated by brushing, dipping, roller coating, spraying, and other methods. The processing layer should be uniform to avoid excessive overflow.
Dry film thickness (DFT) 12-25μm, 20-25μm for harsh environment.
Drying at room temperature takes about 45-60 minutes, and forced drying can shorten the drying time.
This product needs to be stored in a dry room temperature environment to avoid prolonged exposure to high humidity and high temperature environments.
Before heating vulcanization, dip a rag in xylene solvent to remove excess treatment agent spilt around. Once cured, solvent cannot be removed.
Vulcanization of rubber and adhesive at the same time can obtain the best bonding properties. When the coating is placed in the molding mold, it should be quickly filled with rubber vulcanization. The actual curing condition depends on the curing condition of the rubber.
