Features
High build (up to 40 mils in one coat)
Can be spray or hand applied
Excellent adhesion
Service temperature up to 250°F (121°C)
Very low permeability
High abrasion resistance

Application
By Hand:
Prepare surfaces by grit blasting to a clean near white finish, SSPC-SP 10/NACE No. 2. Mix each of the base and hardener to an even consistency. Add the hardener to base and mix until an even color is achieved making sure all sides of container are scraped. Product shall be applied to surfaces ranging from 40°F (4°C) to 220°F (105°C) at a minimum of 30 mils. Immediately pour mixed material onto surface and brush, trowel or roll to required mil thickness. A wet film thickness gauge should be used to measure mil thickness.
Spray:
Prepare surfaces by grit blasting to a clean near white finish, SSPC-SP 10/NACE No. 2. The equipment should be a plural component airless spray unit with a proportioning pump capable of a volume mixing ratio of 3:1. Standard ancillary equipment should include minimum 10 gallon hoppers, static mixers, whip hose, and mastic gun. (Applicator should consult with Denso regarding recommended equipment). Product shall be applied to surfaces ranging from 40°F (4°C) to 220°F (105°C). A wet on wet spray technique should be used to achieve a minimum thickness of 30 mils. The coating thickness should be measured using a wet film thickness gauge.
