ProTXcoat 105

High Temperature Ceramic Fluid

High temperature Acid Resistant Reinforced Repair Fluid

105 is a high performance fluid grade engineering resurfacing compound specifically developed for high temperature immersion conditions (+140 degrees Celcius) and is ideal for tanks, vessels and equipment operating in high temperatures.

105 is based on a complex blend of phenolic epoxy resins and a special polyamino-amide curing system reinforced with abrasion resistant particles to produce a coating with a high level of temperature, abrasion and adhesion properties combined with optimum physical and mechanical strength.

105 has excellent adhesion to most metallic surfaces in one easy application and offers outstanding protection to chutes, hoppers, pipe elbows, valves, pumps and equipment subject to aggressive attack from dry solids and slurries.

Before proceeding, please read the following information carefully to ensure that the correct application procedure is fully understood.


Heavy contamination due to oil or grease must first be removed using MEK (Methyl Ethyl Ketone)

Surfaces should then be abrasive blast cleaned to a minimum Sa21⁄2 – Sa3 BS7079 Part A1 : 1989 or equivalent with a blast profile of 75 – 125 microns corresponding to ‘Rough’ in BS7079 Part C3/ISO 8503/1. All loose abrasive dust and debris must be blown clear or vacuum cleaned away.

Existing steel surfaces which have corroded in a chemical environment may be contaminated by soluble iron salts within corrosion pits. To prepare these surfaces it is recommended that one of the following treatments be carried out prior to final dry abrasive blasting to the specified standard.

a) Blasting with a mixture of clean water and abrasive.
b) Initial dry blast cleaning to remove corrosion and surface coatings followed by high pressure clean water jetting (minimum 1000 psi/66 bar).

105 is a two component solvent free product supplied as a Base component and an Activator component which must be mixed together prior to use.

For optimum application properties the materials should be conditioned/ warmed to a minimum temperature of 20°C (68°F) prior to mixing.

Mix the entire contents of the Base and Activator containers.

The mixed material should be used within 25 minutes of mixing at 20°C (68°F). The time will be reduced at higher temperatures and extended at lower temperatures

For ease of application and optimum performance surfaces should be at a minimum of 20°C prior to 105 being applied.

The mixed material should be applied to the prepared area using a clean brush or squeegee. Application should be carried out as soon as possible after surface preparation is complete, and certainly the same day, otherwise flash blasting will be necessary before application.

In areas where a second layer of 105 is required, this application must be carried out within the initial set time for the first layer, otherwise the surface must be lightly abraded or flash blasted.
