We are now offering mold coatings as an added service to insure the longest life for all your molds and
dies. We have two products that offer increased lubricity to any surface treated. Based on your needs we
will recommend which one is best suited for you.
M1 material is our primary coating. M1 has an operating temperature of up to 750 degrees. For some
die casting applications ,M2 can be used when an operating temperature of up to 950 degrees is
required before some oxidation begins to occur. The coatings are reasonably priced based on quantities
and required masking of areas. Surface wear ratings ( f c = friction coefficient mentioned henceforth) can be
increased dramatically in many cases with our coatings. There are always considerable gains in f c
noted. As an added benefit, there is no dimensional difference after our coatings are applied, as is the
case with many surface treatments. Once applied to surfaces, it is a permanent application and will last
for extended periods. Whenever deemed advisable by your regular maintenance, or if diminished
performance is noted, or upon recommendation by JMF Mold Coatings, the parts can be reexamined and
stripped and reapplied for premium performance.
What If maintenance is required on tooling or engineering changes are required?
Operations like grinding, milling and EDM can be accomplished without consideration for the
coatings. If however, welding or other surface applications i.e. (plating) are to be a part of the
maintenance, the parts should be sent back to JMF Precision Welding for stripping. This is a very low
cost procedure and can quickly and easily be accomplished prior to the welding procedure. We
recommend its application to bearing surfaces , slide by shut-offs, leader pins, gibs, slides, horn pins,
parting lines that receive wear or may be prone to galling, etc…our coatings have been used successfully
on all types of steels, Inconels, and even plastics and rubber compounds. Additionally, perishable
tooling can be coated to increase f c which can increase tool life and even surface finishes. The uses for
these coatings are limited only by the users imagination and specific engineering considerations.
The fc of standard 10W30 motor oil is supplied below to allow customers to compare petroleum lubricants coefficients of
friction to our coatings. This amply demonstrates the vast improvement M1 and M2 allow for wear applications.

HEALTH HAZARD DATA
ROUTES OF EXPOSURE: material can be inhaled, swallowed, or come in contact with the skin or eyes.
EFFECTS OF OVEREXPOSURE: dust and inhalation may cause mild irritation of the nose and throat. With the exception of TOW Russian studies that
found early signs of pulmonary fibrosis in some workers exposed to tungsten trioxide, tungsten metal, and tungsten carbide, most studies have shown that
insoluble tungsten compounds to be toxicologically inert. Skin and eye contact may cause irritation due to the abrasiveness of the dust. Recent scientific
evidence indicates no adverse effects are likely from accidental ingestion of small amounts of the material.
EMERGENCY AND FIRST AID PROCEDURES: inhalation- if symptoms of pulmonary involvement develop, remove from exposure and seek medical
attention; skin contact- if irritation occurs, thoroughly wash affected area with mild soap and water and prevent further contact, contact medical help if
irritation persists; eye contact- if irritation occurs, flush with copious amounts of a water, contact medical help if irritation persists; ingestion- if substantial
quantities are swallowed, give person (if conscious) a large quantity of water to drink, induce vomiting, and seek medical attention; carcinogenic assessmentNTP Annual Report, IARC monographs, et. al.) this material has not been identified as a known or suspected carcinogen by NTP, IARC, or OSHA.
