Liquid Rubber 80
Liquid Rubber 80 is a pourable liquid rubber which cures to form a tough, flexible, rubber-like compound with exceptional tear strength and abrasion resistance. It is painted onto surfaces to provide a protective rubber coating, poured into expansion joints for filling, and cast into moulds to create new or replacement rubber parts.
It is easily applied and bonds to metal, rubber, concrete, fibreglass, wood and many other materials. Coating a surface with it protects against corrosion, wear, abrasion and vibration. Its vibration-resistant properties mean it reduces noise when used to line equipment.
Liquid Rubber 80 repairs damage to rubber conveyor belts and treads, fills expansion joints, and encapsulates parts including electrical components. Encapsulation of sensitive instruments and equipment with Liquid Rubber 80 protects against mechanical and moisture ingress.
When poured into a mould, Liquid Rubber 80 creates highly accurate rubber copies of existing patterns and parts, such as seals, gaskets and elastic supports.
It is self levelling, solvent free and has very low shrinkage. A 20-minute pot life allows enough time for careful application. It achieves a functional cure after 16 hours. Equipment can be put into light service after 10–16 hours and medium service after 24 hours. A full cure is reached in seven days.
A faster curing version is available for reducing equipment downtime and the rapid casting of new or replacement parts. Liquid Rubber Rapid 5 Minute which comes with a pot life of 5 minutes and a light handling time of two hours.
Liquid Rubber 80 Details
Surface preparation is required before application. Full instructions detailing the preparation for specific substrates can be found on the Technical Data Sheet and are provided with the product. A primer should be used for best results and maximum adhesion.
Part A and Part B are mixed at a 100:60 ratio by weight or 100:66 by volume. To ease the mixing process, the Part A container has enough room to dispense all Part B into, enabling it to be applied with a brush straight from the container.
To repair worn and damaged rubber parts, Liquid Rubber 80 is poured into holes and tears to a thickness of at least 3mm to provide sufficient strength. It will cure to seamlessly fill the damage with a new rubber surface.
For filling expansion joints, it is poured into the joint from one side and allowed to fill the entire area. The joint is filled to 1mm below the height of the concrete to prevent overfilling.
When creating new parts or replacement components, a mould must be taken of the original. Liquid Rubber 80 is poured into the mould, where it will cure to form an exact copy of the original.
For lining applications and noise reduction, it is applied via brush to surfaces to a thickness of at least 1.5mm. Applying multiple layers will build up a thicker, longer lasting, more resistant coating. The re-coat time of Liquid Rubber 80 is 12 to 24 hours.
Equipment can be put back into light service after a minimum of 10 hours. Once cured, the repair can be ground flush. Details of this process are also included on the Technical Data Sheet.
