Carboline Carbotherm 551 is unique insulative composite two-component coating formulated in a high temperature resistant epoxy binder. Unlike acrylic-based insulative materials it has superior toughness, hardness, impact resistance, chemical resistance and permeation resistance. It is therefore more suitable for industrial applications or other physically demanding environments. It is an ideal protective heat barrier to shield personnel from hot surfaces. It also inhibits heat transfer into or out of a structure. Its insulative properties keeps structures exposed to solar radiation significantly cooler.

Carbotherm 551 can be used to minimize or eliminate condensation of pipes or other operating equipment. Its superior application properties of higher film build per coat and fewer coats offers savings and quicker return to service. Because it bonds directly to the surface (unlike standard insulation materials) it minimizes water entry and the effect of corrosion under insulation.

Product Specification

Drying Times

• These times are based on a 1000 micron dry film thickness. Higher film thicknesses, insufficient ventilation, high humidity, or cooler temperatures will require longer cure times
• If a final colour coat (see Topcoats) is used; allow 24 hours dry time 23°C to ensure adequate dryness prior to final colour coat

Surface Preparation

General

• Surfaces must be clean and dry
• Employ adequate methods to remove dirt, dust, oil, and all other contaminants that could interfere with adhesion of the coating

Steel

• Prime with appropriate primers as recommended in section on "Primers"

Stainless Steel

• Abrasive blast to a 1-1.5 mil profile and apply material direct to substrate or over appropriate nonzinc primer

Application Methods

Application Conditions

• It is best to spray apply a light 5-10 mil coat and allow to tack dry prior to full coating. This is especially helpful over hot surfaces 65-121°C which may require 2-4 light passes
• Do not apply when the surface temperature is less than 3°C above the dew point.
• Do not apply if temperatures are expected to drop below 10°C within 24 hours of application
• Special application techniques may be required above or below normal application conditions
• Dry times will be aided by higher temperatures, lower humidity, hotter substrates, and more air movement during application and curing

Health and Safety

Clean Up

• Use Thinner 2 or Acetone
• In case of spillage, absorb and dispose of in accordance with local applicable regulations
