A Rope Dressing.


Conventional rope dressings aim to provide an envelope or skin which will be impervious to water or gasses are widely used and their effectiveness depends on, amongst other things, on both the extent to which the envelope remains intact and on its penetration into the rope.

With locked coil ropes penetration with these conventional products is difficult to achieve without sacrifice of other requirements. For friction winders a third requirement is that it should not decrease the friction between the rope and the drum. Bryto P1 exhibits no lower co-efficient of creep or static friction that transformer oil.

Product Description

Bryto P1 is a pump able rope-dressing product offering effective corrosion protection. The penetration of the  Bryto P1 is specifically controlled, resulting in a very thin film of chemical barriers by  chemisorptions, as opposed to mechanical protection. The films formed are of molecular dimensions and are very difficult to dislodge.


Bryto P1 is particularly suited for locked coil ropes whatever their application, in addition to conventional triangular or flattened strand ropes on friction winders (Koepes) since the co-efficient of friction is a consideration.


Bryto P1 is recommended for protection of all ropes. The fluidity of the product allows it to be applied by swab or brush on short ropes, but on deep shafts application is better by a pressure spray rig operated periodically, a little and often. The product is easily pumped and will not clog jets.Features and Benefits

Excellent  Corrosion Protection Bryto P1 will provide corrosion protection not normally found with thin film rope dressings. Bryto P1 has shown to be effective in situations where weak acids, rust powder and coal dust contamination occur.


The product shows powerful penetrating  properties, allows the rope internals to be reached, providing internal corrosion protection and reducing chafing.

High co-efficient of friction

Bryto P1 has a  much higher coefficient of friction than that of conventional rope dressings, the use of which is hardly possible on friction winders.
