High Temperature Industrial Floor Coating

Chemical Resistant Floor Coatings


PERMACOAT 4000 HT is a 100% solids epoxy floor coating designed for high temperature applications commonly found in many manufacturing processes. PERMACOAT 4000 HT is designed to withstand constant temperatures to 212 degrees F (100 degrees C) and intermittent exposures to 250 degrees F (122 degrees C). When elevated chemical exposures are anticipated, contact ChemProof Polymers for specific recommendations.

PERMACOAT 4000 consists of two components, resin and hardener, in both the horizontal and vertical formulations. Its application is accomplished with rubber squeegees and short nap paint rollers.


PERMACOAT 4000 HT is designed as a heavy duty (30-90 mils) floor coating and/or secondary containment system where extensive mechanical abuse and chemical exposures are anticipated. PERMACOAT 4000 HT can be installed over most sound substrates, including old or new concrete, steel and wood. PERMACOAT 4000 HT provides a costeffective alternative to high build floor toppings.


PERMACOAT 4000 HT allows for a fast, easy application. It also offers chemical resistance higher than those found in paints and other thin mil coatings.

NOTE: At 30-50 mils, PERMACOAT 4000 HT provides excellent chemical resistance for splash and spill exposures. In addition, when applied at 50-80 mils, it can often be recommended for containment service. (For specific recommendations, refer to the “Chemical Resistance Guide” and your local distributor.)

Other Features Include:

  • - Rapid cure resulting in minimal downtime
  • - Very low odor
  • - Non-skid safety finish

Packaging and Coverage

PERMACOAT 4000 HT is packaged in one and three gallon units. Each unit consists of pre-measured components, Part A (Resin) and Part B (Hardener).

Application thickness may vary from 30-90 mils, depending on the expected service conditions. Factors to consider are 1) mechanical abuses and 2) substrate texture.

Cure Time

The cure time of PERMACoat 4000 HT and other resinous systems are very dependent upon the temperature of the substrate. The chart below represents the approximate times for the respective service conditions, following the last coat:

Mixing & Application

Prior to application of PERMACOAT 4000 HT, the resin, hardener and substrate should be between 70 degrees F and 95 degrees F.

Premix the Resin (Part A) for 30 seconds using a Jiffler mixer blade attached to a 500-750 RPM drill. Add the Hardener (Part B) only when the batch is ready to be applied. Mix for approximately 90-120 seconds. After mixing, pour immediately onto the floor.

Use a rubber squeegee to spread the resin over the premeasured area to be covered. Immediately back roll the PERMACOAT 4000 HT with a short nap (1/8 inches) wool or mohair roller. At this point, several pre-specified readings should be made with a wet mil gauge to assure uniform coverage. After the coating has been back rolled and uniform thickness verified, the surface should be saturated with a silica broadcast.

After the first coat supports foot traffic, the excess silica can be removed. Within 24 hours a second coat of PERMACOAT 4000 should be applied using the same procedure, minus the silica broadcast.

NOTE: Additional broadcasts and roll-coats can be utilized to increase floor thickness.


All mixing and application equipment should be cleaned immediately after use. If this is done, soap and water or biodegradable cleaners can be used. If the material has begun to set, more aggressive solvents will be necessary. Before using solvents, refer to their respective SDS for handling considerations.


For systems designed for splash and spill exposures, routine wash downs are recommended to reduce the length of chemical exposure. This step is not necessary where the product is recommended for containment service.

Storage and Shelf Life

PERMACOAT 4000 HT should be stored at 50-90 degrees F out of direct sunlight. All containers should remain unopened until ready for use. If stored as set out above, PERMATEC 4000 HT has a minimum shelf life of one year.

Where Permacoat 4000 HT Should Not Be Installed

PERMACOAT 4000 HT should not be applied over substrates:

  • which are wet during the application
  • subject to hydrostatic pressure
  • which are unsound
  • which are contaminated and cannot be cleaned
  • at temperatures below 50 degrees F (Consult ChemProof Polymers)


Read Safety Data Sheets (“SDS”) before using. PERMACOAT 4000 HT contains blended Epoxies as the resin and blended Amines as the hardener. Protective clothing and gloves are recommended to prevent sensitization to these materials. In case of ingestion or eye contact, it is advisable to contact a physician immediately. SDS are available for this product upon request.
