Solvent-borne Self-curing Inorganic Zinc Silicate Coating
Honestjoy's liquid HJ-3029 with zinc metal pigment HJ-197
Description: HJ-996M is a two-component, medium-zinc, solvent-borne, selfcuring
inorganic zinc silicate coating. Applicable by airless spray.
Recommended use: As a general purpose rust-preventing primer in paint systems for long-life protection of
steel exposed to moderately to severely corrosive environment.
Service temperatures: Maximum service temperature is depending on the subsequent coat.
Colours: Metal grey
Volume solids, %: 61 ± 1
Theoretical spreading rate: 12.2 m²/litre - 50 micron
489 sq.ft./gallon - 2 mils
Flash point: 14°C/57°F
Specific gravity: 2.4 kg/litre - .0 lbs/gallon
Dry to touch: 30 (approx.) min. at °C/68°F (75% RH)
Fully cured: 16 (approx.) hours at °C/68°F (75% RH)
V.O.C.: 545 g/litre - 4.5 lbs/gallon
Shelf life: 6 months (25°C/77°F) for liquid 10C and 3 years for our zinc metal pigment HJ-197 (stored in closed container) from time of production.
Shelf life is dependent on storage temperature. Shelf life is reduced at storage
temperatures above 25°C/77°F. Do not store above 40°C/104°F.
Shelf life is exceeded if the liquid is gelled or if the mixed product forms gels before

Safety: Handle with care. Before and during use, observe all safety labels on packaging and
paint containers, consult Honestjoy Material Safety Data Sheets and follow all local or
national safety regulations. Avoid inhalation, avoid contact with skin and eyes, and do
not swallow. Take precautions against possible risks of fire or explosions as well as
protection of the environment. Apply only in well ventilated areas.
SURFACE Remove oil and grease, etc. with suitable detergent. Remove salt and other contaminants by
PREPARATION: (high pressure) fresh water cleaning. Abrasive blasting with sharp abrasive to minimum Sa 2½ with
a surface profile equivalent. In case of new steel to be exposed to no more than medium
aggressive (industrial) environment and without any extraordinary demands to lifetime, a surface
preparation degree of SSPC-SP6 may suffice.
Consult separate APPLICATION INSTRUCTIONS.
APPLICATION From 0°C/32°F to 40°C/104°F. Curing needs minimum 65% relative humidity and is very retarded
CONDITIONS: at lower temperatures. Furthermore consult separate APPLICATION INSTRUCTIONS.
SUBSEQUENT According to specification. Recoating is expected to take place within 6 months after application
COAT: of HJ-996M.
Service HJ-996M may be used for high temperature service if overcoated with
temperature: Honestjoy's Silicone Aluninum 910A.
In such a case it will be resistant to permanent dry temperatures up to 500°C/932°F. In case of
cyclic service conditions with regular periods of low and high temperatures it is recommended to
keep the maximum temperature below 400°C/752°F.
Note: If used as anticorrosive protection under insulation of high temperature equipment it is very
important that NO moisture can penetrate during slowdown periods. This to avoid risk of "wet
corrosion" when the temperature rises.
Film thicknesses: 50 micron/2 mils dry film thickness is recommended, but 75 micron/3 mils dry film thickness
(125 micron/5 mil wet) may be specified, this will alter spreading rate and may influence drying
time and recoating interval.
(The dry film thickness range does not take into account the correction factors for rough surfaces
Mixing: When mixing part of the content in a can the mixing ratio on volume should be made as follows:
Measure 8.0 parts of liquid 10C and then add our zinc metal pigment H-197 up to a total
of 10.0 parts by volume.
Thinning: For application at high temperatures, a special thinner is available.
Recoating: Recoating intervals are strongly dependent on both temperature and humidity. Deviations from the
standard conditions may shorten or prolong the recoating intervals.
Full curing will be obtained after:
0°C/32°F and min. 75% RH: 3 weeks
10°C/40°F and min. 75% RH: 6 days
°C/68°F and min. 75% RH: 16 hours
(a certain curing does take place at temperatures below the freezing point, but at an extreme low
speed). Furthermore consult separate APPLICATION INSTRUCTIONS.
