Product Description

GP3741 NOVO-FLO SOLVE NT / ACID RESISTANT COATING is

a pigmented, high-build, high solids Novolac epoxy which resists

vapor, splash, spillage or immersion to certain aggressive acids,

alkalies and solvents. This material bonds aggressively to properly

prepared and primed substrates, protecting the substrate from

damaging chemicals.

Advantages

• Protects against certain aggressive acids, alkalies and

solvents. Refer to the Chemical Resistance Guide.

• High bond strength

• Rapid cure

• Initial high gloss

• Moisture tolerant

Typical Uses

GP3741 NOVO-FLO SOLVE NT / ACID RESISTANT COATING

protects surfaces in petroleum refineries, chemical processing,

water treatment, waste water treatment, power utilities, pulp and

paper, food and beverage and pharmaceutical facilities.

Limitations

• Slab on grade requires vapor/moisture barrier.

• Substrate must be structurally sound and free of bond inhibiting

contaminants.

• During installation and initial cure cycle, substrate and

ambient air temperature must be at a minimum of 50ºF (10ºC).

Substrate temperature must be least 5ºF (-15C) above the dew

point (for lower temperature installation contact the Technical

Service Department).

• When required, adequate ventilation shall be provided and

proper clothing and respirators worn.

• Strictly adhere to published coverage rates.

Surface Prepa ration

Proper inspection and preparation of the substrate to receive

resinous material is critical. Read and follow the “Instructions for

Concrete Surface Preparation” (Form G-1) for complete details.
