Rubber repair & Seal

Application instructions

Rubber repair: In the mining industries, if not repaired timely the local scratch or abrasion of conveyor belt, rubber tape(tube), various rubber blades & rollers due to accidental or unavoidable emergency, which will easier to cause the serve abrasion and make influence on equipment long-term usage.

High temperature sealing material: Paste luting agent/sealing material for industrial use wherever conditions of temperature combined with pressure on smooth, plane sealing surfaces (butt joints) make extreme demands on the quality of the sealing compound.

Application ranges

• Repair damaged conveyor belt, rubber belt, rubber tubing and various rubber blades.
• Repair scratching rubber rollers, all kinds of tire casings and inner tubes.
• Sealing of metallic joints in steam and gas turbines, compressors, generators, expanders, pumps, flange,
joints, etc.

Material performance

• Excellent adhesion, bonds to all rubber and hard surface.
• Super flexibility.
• Excellent abrasive resistance.
• Excellent chemical resistance.
• Withstands hot steam and air, hot and cold water, light fuel oils and lubricants, as well as crude oil and natural gas at temperatures of up to 900 ºC.
• The adhesion on sealing surfaces and butt joints is so high that a one hundred percent seal is guaranteed even for pressures up to 250 bar.
• The pressure resistance for flanges without sealing rings is guaranteed up to 450 bar, and even up to 550 bar for screw joints.
