Metal Repair & Protect

Application instructions

Abrasion reasons:

Most of equipments in industries are always large styles, which are complex to realize detachable repair. In the equipment operating service, it always leads to shaft damage, also appears bearing house abrasion due to inaccurate setting, timeless maintenance and insufficient lubrication. Traditional means generally adopt surfacing machining to realize repairing, but surfacing will elevate surface of parts to a very high temperature, make parts appear distortion or crack, obtaining sizes by machining will extremely extend shutdown time.

Scratching reasons:

In the production, due to friction or slip, the surface of products or equipments will appears visible deep point, line or lump damage called scratch, such as hydraulic cylinder, hydraulic arm, etc sealing parts injured by strain and scratch, create oil &gas leakage, thus make equipment out of operating, additionally, if purchasing or replacing parts, would be more expensive, time-consuming and influence normal production scratching always appears in various roller surface, finally influence product quality.

Application ranges

• Abrasion grade repair: shaft, shat liner, bearing block, keyway abrasion and thread slipscrew, etc.
• Scratching grade repair: surface scratching of slipway, pipeline, tank surface, roller, etc smooth substrates.

Material performance

• Adhesion to metal, concrete, plastic, etc hard surface;
• Excellent anti-high temperature, corrosion and erosion
• Good machinable & abrasion resistant
