CRC SP-400 Wax Based Aniti Rust Coating

Product Description

1. GENERAL DESCRIPTION

Long-term outdoor and indoor corrosion inhibitor. CRC SP 400 ANTI

RUST COATING is a long-term, outdoor and indoor corrosion inhibitor for

machined surfaces and assemblies subjected to long periods of storage or adverse

shipping conditions. the amber, dry, waxy film never becomes brittle and is highly resistant

to humidity and severe corrosive atmospheres.

2. FEATURES

Long-term protection (up to 1 year outdoors) for all metals during shipment or extended storage

Waxy film seals out moisture effectively

Highly resistant to humidity and salt spray

Can be removed or diluted, for film thickness variation, with petroleum solvents

Aerosols use hydrocarbon propellant for controlled application and film thickness

Specifications :

meets Mil-C-16173, grade 4

NSN 8030-17-039-7214

USDA, class P1

3. APPLICATIONS

Protection of finished components, in-process parts, in-transit goods, raw materials, structural steel.

Effective corrosion shield for overseas shipments, winterising of farm machinery, outdoor storage.

Protection of equipment, tools, dies, molds, jigs, pipes, shafts, housings, wire ropes, valves, gears.

To be used for brine and chloride resistance in refrigeration plants.

In paper and pulp plants.

As a cable end sealer and pipe joint protector in utilities .

Protection of air conditioning and electrical equipment in hospitals and educational institutions.

In airport and aircraft maintenance and construction.

4. DIRECTIONS

Shake aerosol can well before use. Stir or mix bulk product to break its paraffin

structure before dipping or brushing applications.

Mask area not to be treated. If necessary, remove by solvent cleaners

(CRC Fast Dry Degreaser, CRC Industrial Degreaser)

Film thickness may be adjusted by thinning with petroleum solvents,

but corrosion resistance varies with film thickness (see typical properties)

For applications in wet or very humid conditions, CRC 3-36 should be

applied first for complete moisture displacement. Allow then 2 to 4 hours

for solvent evaporation before SP 400 is applied.

When finished spraying, clean aerosol valve by turning can

upside down and pressing actuator until only propellant escapes.

Do not use on energised equipment. Use in well ventilated areas.

A Safety data sheet (MSDS) according EU directive 93/112 is

available for all CRC products.
