DTM EPOXY MASTIC 
.DESCRIPTION AND USES   . 
A two-component, high solids epoxy coating for use in 
moderate to severe environments. It is specifically designed 
for application directly on sound rusted steel with minimum 
surface preparation. It can also be used on clean steel, 
galvanized metal, concrete (including concrete floors), 
previously coated and slightly damp surfaces. It may also be 
used for water immersion service, using High Performance 
Industrial DTM Epoxy Mastic standard premix bases only with 
9102402 Immersion Activator. (Note: Do not use for 
immersion service in potable water tanks). High Performance 
Industrial DTM Epoxy Mastic can be used indoors or out. 
While exposure to sunlight and certain interior lighting 
conditions causes fading and chalking of all epoxy type 
coatings, these changes are cosmetic in nature only and film 
integrity and performance will not be adversely affected. 
Epoxy coatings will yellow with age. This is most noticeable 
with interior applications of white or light colors which are not 
subjected to bleaching from Sunlight. Note: 9102402 
Immersion Activator and 9104402 Fast-Cure Activator 
produce a semi-gloss finish. Also,using the 9104402 Fast- 
Cure Activator may result with a slight colorshift when 
compared with products using the 9101402 Standard 
Activator.
