Rubber to Metal Adhesive 829GB - Replace to Chemlok 6411, Chemosil
NL 411, Cilbond 80E, Megum 538/128
Application
Rubber to Metal Adhesive 829GB is primarily designed for double coating and post-curing
applications, effectively promoting adhesion between various
elastomers and their base rubber or substrates. This product
consists of a blend of polymers, organic compounds, and mineral
fillers, all dissolved or dispersed in an organic solvent system. Rubber to Metal Adhesive 829GB boasts exceptional resistance to harsh environments and
facilitates an efficient spraying process, allowing it to be
applied as a stock solution using appropriate techniques. When used
in conjunction with the Dual Coat substrate surface treatment
agent, it is suitable for a range of rubbers, including 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),
Butyl Rubber (IIR), and EPDM.

Applying 829GB
Stirring: Rubber to Metal Adhesive 829GB in the long-term storage process will have some precipitation at
the bottom of the container, before the glue must be fully stirred,
to achieve uniform mixing before use; If the gluing process is
long, stir at a high speed for 3-5 minutes at an interval of 2
hours.
Dilute: According to the actual operation needs, this product can
also add diluent for appropriate dilution. It is recommended to dilute the diluted product according to the
amount used. The diluted product cannot 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 plus about 10-30 parts of diluent;
Spray method: 100 parts Rubber to Metal Adhesive 829GB plus about 20-40 parts diluent.
Coating: Rubber to Metal Adhesive 829GB can be applied by brush coating, dip coating, roll coating, spray
coating and other methods. Coating should be uniform to avoid
excessive spillover.
Cover coating: Dry film thickness(DFT) 12-25μm. 20μm is recommended
20-40μm for harsh environment;
Single coating: DFT 15-25μm, 22μm is recommended. for PV- bonding
above 25μm;
Drying: Drying at room temperature takes about 45-60 minutes,
forced drying can shorten the drying time,recommended drying
temperature is 60-80℃.
Product storage: Rubber to Metal Adhesive 829GB should be stored in dry and normal temperature environment, avoid
long-term exposure to high humidity and high temperature
environment.
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.
Notes
- Rubber to Metal Adhesive 829GB is volatile, please close the container after use.
- Solvent steam is harmful, pay attention to fire prevention in the
workplace, pay attention to low ventilation, prevent long-term
inhalation or long-term skin contact.
- Please refer to SDS for more safety information.
