Plasmet T
Product reference: 5/09
Product title: Plasmet T
Valid from: 3rd February 2006
Last reviewed: May 2019
Type
A solvent free, two-pack smooth surfacing material with good chemical
resistance.
Suggested use
Overcoating Plasmet ‘R’ to give smooth surface finish but
can be applied directly to metal surfaces where re-building
is not required. May be cast or ground to give an excellent
surface finish for use in sealing areas.
Health & safety
Warning:When using this product safety precautions should
be observed. Avoid contact with skin or eyes. Do not ingest.
Protective clothing and goggles should be worn. Read Safety
Data Sheet before use and observe all precautions.
Surface preparation
Surface should be free from oil, grease and other
contaminants. It should also be roughened to provide a
suitable key. Where possible, for optimum performance
and adhesion, surfaces should be abrasive blasted before
application of Plasmet ‘R’ to SSPC-SP10 (IS0 8501-1
Sa 2½) or equivalent with 3 mil (75 micron) profile in
accordance with data sheet SP1. Surfaces should be
dry
Application equipment
Brush, trowel or other suitable implement.
Application equipment
Trowel or short hair, stiff brush.
Application
Plasmet ‘T’ should be applied thinly enough to avoid runs or
sags in the coating.
Mixing ratio / mixing
2.5:1 Base to activator by weight.
Pour all of component ‘A’ into component ‘B’ and mix
thoroughly. The material is now ready for use and should be
applied as soon as possible. Product should not be applied
at temperatures below 41°F (5ºC).
Pot life
Variable with temperature and mass, but approximately:
68°F (20°C): 50-90 minutes
86°F (30°C): 50-60 minutes
95°F (35°C): 40-50 minutes
Packaging
1 and 5 gallon kits
Storage life
2 years minimum in unopened tins, stored at 41-104°F (5-
40°C).
Color
Black
Specific gravity
0.04lbs/cubic inch (1.2 gms/cc).
Flash point
In excess of 212°F (100°C)
Catalyst type
Modified clyclo-aliphatic/aliphatic amine
Chemical resistance
Good.
Abrasion resistance
Good.
Mechanical strength
High.
Cleaning solvent
Xylene, Toluene, Methyl Ethyl Ketone.
Cure time
Variable dependent upon film thickness and temperature, but
at 68°F (20°C) tack free 8-9 hours and full cure 4-5 days.
However, material may be usable in service before full cure is
attained. Post cure at temperatures up to 212°F (100ºC)
speed cure, improve hardness and aid machining, see
below.
Should a second application of Plasmet ‘T’ be required, this
should take place within the over coating times specified
below.
Overcoating
Where more than one coat is required, Plasmet ‘T’ should be
over-coated with itself within the following time periods:
Ambient temperature
32-50°F (0-10°C Minimum 24 hours, maximum 36
hours.
50-77°F (10-25°C) Minimum 7 hours, maximum 18
hours
77-95°F (25-35°C) Minimum 3 hours, maximum 12
hours
At low temperatures and high humidity, amine bloom may
occur, evidenced by a dull greenish tinge on the surface.
Where this occurs the bloom must be removed by abrading
the surface before over coating is carriedout.
