High Elasticity Heat Resistance Mechanical Strength Rubber to Metal Bonding Agent 823GB As Production Of Tires, Hoses, And Rubber Shoes

(Equivalent to Chemlok 220LF/6125/6220, Chemosil 225/222/222NL, Thixon 520/526) 

1. Description
 Rubber to metal bonding agent 823GB is 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) polymers to metal.
 2. Purpose
 Surface treatment agent used for bonding rubber to metal as a cover coat.
 3. Applicable Range
 Used as a cover coat adhesive and in combination with a primer adhesive, suitable for the following types of
 rubber:
Natural rubber (NR), Natural & butadiene rubber (NR+BR), Polyisoprene rubber (IR), Butadiene rubber (BR),
 Chloroprene rubber (CR), Styrene butadiene rubber (SBR), Nitrile butadiene rubber (NBR), etc.
 4. Features and Benefits
 Environmentally friendly, Compliant with GB 33372-2020.
 Free of heavy metal elements.
 Good construction performance.
 Excellent fatigue resistance.
 Excellent weather resistance - heat resistance, water resistance, solvent resistance, oil resistance, salt spray
 resistance, corrosion resistance.
 5. Performance
 Components: polymers, organic compounds, inorganic fillers and organic solvents.
 6. Typical Properties

7. Application
 Stirring: During the storage process of 823GB, 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.
 Diluting: 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, or 100 parts of 823GB and 10 parts of diluent. 
Roller coating method: no dilution is required, or 100 parts of 823GB and 10 parts of diluent. 
Dip: 100 parts of 823GB and 20-30 parts of diluen. 
Spray method: 100 parts of 823GB and 50-100 parts of diluent. 
Coating: This product can be coated by brushing, dipping, roller coating, spraying, and other methods. The 
processing layer should be uniform to avoid excessive overflow. 
Cover coating: Dry film thickness(DFT) 10-20μm. 
Drying: Drying at room temperature takes about 45-60 minutes, and forced drying can shorten the drying 
time. 
Product storage: This product needs to be stored in a dry room temperature environment to avoid prolonged 
exposure to high humidity and high temperature environments. 
Cleaning: Before heating vulcanization, dip a rag in xylene solvent to remove excess treatment agent spilt 
around. Once cured, solvent cannot be removed. 
Vulcanization: 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. 
8. Shelf Lift/Storage
 Shelf life is 12 months from date of shipment when stored at ＜ 37°C in original, unopened container. Do
 not store or use near heat, sparks or open flame.
