Water Base Coating

Zircon Water Base Coating -RSJ 1419W

Description

RSJ –1419W is coating material based on Zirconium. (Zircon Flour).Water is used as carrier liquid. The newly – designed binder and suspension system gives this coating material best application properties. A high solid content assures a dense layer and thus an excellent protection against penetrations and mould metal reaction. It also maintains a good adhesive and abrasive resistance.

Composition

Form Supplied Ready Mixed.
Refractory Zircon
Carrier Water.
Colour White

Technical Data

Solid Content: 70 + 1% Density: 2.0 to 2.5

Standard Packing

RSJ – 1419W is available in 50 kg Carboys.

Shelf Life

RSJ – 1419W has a shelf life of 6 months. Should be stored in a cool and dry place. Lids of partly used carboys should be replaced tightly.

Graphite Water Base Coating - Gp 1419w

Description

A black, easily-workable paste, GP-1419W, contains a mixture of crystalline and amorphous graphite’s. It is readily reduces in water.

Characteristic

GP-1419W is particularly suited for light section iron castings where finish, dimensional accuracy and complete peel are most important. It is effective at extremely low solids content which provides excellent economy in use.

Automotive cylinder head jackets, motor body, manifolds and other cores for light, precision castings of this type are ideal for GP-1419W. Oil sand, shell and hot box cores can be coated by spray, dip or automated coating system. The total absence of foam and high dilution of GP-1419W allow coating of hot cores from shell or hot box operations without residual pock-marking or excessive coating build-up.

Cores with difficult-to-wet surfaces can be coated by using 10-20% alcohol in place of some of the water. The cause of the problem is usually surface density, wax or parting agents on the core. This alcohol addition (isopropyl alcohol is recommended) does not improve penetration and wetting of the core surface.
