conveyor belt surface repair, joints splicing, drum and rubber sheet bonding, also conveyor belt has super 

bonding strength between metal and rubber, rubber and rubber, fabric and rubber, fabric and fabric.

Features of conveyor belt adhesive SK811
Short solidify time under normal temperature, high intensity, corrosion resistance, aging resistance, flexible 

resistance and Non-flammability.

Easy operation technology, no need for vulcanizer or other large scale equipment, once repair can use 

immediately.

Can be used under the temperature of 0 to 80℃, especially for underground fireproof and explosion proof 

environment.

Instructions of conveyor belt adhesive SK811

Metal: use sand blast or grinding methods to derust the metal surface and make it rough- s est the grinding 

depth will be 30um, use Dipute cleaning solvent Sk353 to dislodge surface grease, if have to, pls brush a coat 

of metal primer SK363 and wait it totally dry, thus will enhance the bonding strength between metal surface and 

rubber.

Rubber: rubber sheet with semi-cured layer and repair strip whose surface don’t have to be ground, if rubber 

sheet without semi-cured layer, whose rubber surface have to be totally ground( do not have smooth area), use 

dry and clean brush to wipe off the dust, use cleaning solvent to wash the metal stains.

Fabric: brush other rubber area and make them flatten, grind the fabric layer carefully, (note that do not 

damage the fabric layer, s est using the tungsten carbide buffing disc), use dry and clean brush to wipe off 

the dust, use cleaning solvent to wash the metal stains.

Blending: stir conveyor belt adhesive SK811 and hardener UT-R40 fully,mix ratio will be 100:4, pls use the 

mixture in 2 hours.

Brush: brush the jointing surface uniformly twice, first brush will have to wait totally dry(at least 30 

minutes, metal surface at least need an hour), the second brush will be dry and have little stickness ( test 

with finger back), if over dried, pls brush again.
