chemlok® xj-549 adhesive
Chemlok XJ-549 is the top coat of double-layer system adhesive, and it can be used in conjunction with the primer Chemlok205TW for the bonding of elastomers and metals, or for the bonding of various non-polar elastomers. This product is a mixture of various polymers, organic compounds and inorganic fillers dissolved and dispersed in organic solvents. ChemlokXJ-549 is used for bonding IIR and EPDM, and it can also bond other kinds of elastomers such as NR, IR, SBR, BR, CR, NBR.

Features and Benefits
Applicability - can be bonded to non-polar rubber elastomers such as IIR and EPDM. coating
Simple - the coating method is simple, brush, dipping, spraying can be used.
Instructions
SURFACE PREPARATION - Thoroughly clean metal surfaces before applying adhesive. Use a solvent-based degreaser or alkaline cleaner to degrease metal surfaces. Choose the appropriate chemical cleaning or mechanical cleaning method to remove the oxide layer on the metal surface.
Stirring - In order to make the active ingredients of XJ-549 in a uniform state, it should be thoroughly stirred before use, and it should also be stirred properly during use. Drying - When coating XJ-549, the substrate surface temperature should be controlled below 60°C. The drying time at room temperature (natural drying) is about 25°C x 30-60 minutes (when the humidity is not high), and the forced drying should be controlled within the range of 60~80°C x 10-15 minutes. Coating - Can be applied by brush, dip or spray. In order to achieve the best bonding strength, the required range of coating film thickness (dry film) is 10~25μm, and the best performance can be exerted within this range. When secondary vulcanization is followed by vulcanized rubber, the dry film thickness needs to be 15~38μm. XJ-549 can be diluted according to the coating method. After dilution, the adhesive is easy to precipitate, please pay more attention to stirring evenly.
Next - XJ-549 can be vulcanized and bonded with rubber after it is fully dried, and the adhesive will harden during the molding process. Please pay attention not to put additional load on the bonding interface as much as possible when demoulding immediately after molding. Secondary vulcanization and bonding For vulcanized rubber, please apply XJ-549 on the adhesive surface, apply 5~10% compression deformation to the rubber after fully drying, and heat at 144~177°C for 20-40 minutes. Keep the pressure on after heating until cooling.
