Coating Industry

Rubber covered rollers are used in metal decorating applications to apply paints, varnishes, and UV coatings. The coverings utilized in these applications require chemical compatibility with the Ester, Aromatic or Water based solutions which are applied to various metal substrates. Typical metal coating applications are aluminum beverage cans and window blinds. These coverings have been very successful in their own right, but consideration for the operating environment is essential to select the most suitable covering.

Coverings Hardness Range Max Temperature Chemistry
Polar-Rite™ 30-70 Shore A 350° F Esters & Ketones
Val-Rite™ 40-70 Shore A 250° F Water Based
Dura-Coat® 40-70 Shore A 300° F Water Based
Val-Rite™ Plus 40-70 Shore A 250° F Aromatics


Wood Industry

Rubber covered rollers are used in the wood applications to apply stains, varnishes, glue pressed wood, and sanding operations. The coverings utilized in these applications require chemical compatibility with the stains, varnishes or Water based solutions which are applied to various wood products.

Food Industry FDA Coverings

Rubber coverings are used in variety of applications in contact with food and potable water. Due to the close contact of these articles with items intended for human consumption, lawmakers around the globe have produced appropriate legislation in order to avoid any health hazards that might be associated with their use. In the United States the Food and Drug Administration regulations outline the specific parameters for rubber articles intended for repeated use in contact with food. Rubber Rolls intended for producing, manufacturing, packing, processing, preparing, packaging, transporting or holding food are subject to the FDA 177.2600 statues. Valley Roller will certify that our FDA coverings contain the specific ingredients and appropriate levels. It is the responsibility of the end-user to obtain the necessary FDA approval for the roll itself.

Silicone 30-80 Shore A 500° F
Val-Rite™ FDA 40-90 Shore A 275° F
Dura-Coat® FDA 40-90 Shore A 300° F

Leather Industry

There are a variety of roll applications where coverings are exposed to abrasive substrates which can alter surface finish and roll geometry. In these applications it is essential that the roll coverings are formulated to maximize resistance to abrasion. This is accomplished through the selection of the base polymers and filler systems so that improved resistance to abrasion can be realized. Valley Roller offers several coverings that have been specifically designed for abrasive roll applications and environments. These coverings have been very successful in their own right, but consideration for the operating environment is essential to select the most suitable covering.

Coverings Hardness Range Max Temperature
Val-Coat® 50-99 Shore A 325° F
Valthane® 45-95 Shore A 275° F
Dura-Coat® 35-95 Shore A 300° F
