About STP ShaliKote C

STP ShaliKote C is a 2K anti-corrosive ceramic epoxy coating built for one of the toughest problems in industrial asset protection: surfaces that are being worn away and chemically attacked at the same time. When slurry, effluent or gas carrying a high load of solid particles moves through pipelines and channels at speed, it does two things at once. It erodes the surface mechanically and it corrodes whatever is exposed underneath. A conventional epoxy handles the chemistry but not the wear; a hard wear coating often fails the chemistry. ShaliKote C is engineered to hold both fronts. The film pairs an epoxy resin system with a specific ceramic filler, cured using a modified cycloaliphatic amine, so the cured coating is both hard and chemically durable.

The ceramic filler is the defining feature. It maximises abrasion resistance and thermal shock resistance, giving the film the toughness to survive scouring flows that would strip a plain epoxy. The cycloaliphatic amine cure, meanwhile, delivers better UV tolerance than a standard amine epoxy along with strong acid and alkali resistance. For Indian plants running effluent drainage lines, wastewater treatment channels and coke oven gas ducts, that combination is exactly what keeps steel and concrete in service instead of on a repair schedule. Space Arc Engineering supplies ShaliKote C as an authorised STP channel partner, with site guidance on primer selection, DFT control and substrate readiness so the specified performance is what the asset actually gets.

The technical insight

The performance comes from how the two halves of the formulation divide the work. The epoxy backbone, crosslinked by the modified cycloaliphatic amine, forms a dense, low-porosity film that resists water, acids and alkalis and cures with a tighter network than a standard aliphatic-amine epoxy, which is why it holds up better under UV and against chemical soak. On its own that film would still abrade under a high-velocity particle stream. The ceramic filler solves that: hard ceramic particles are distributed through the binder so the incoming solids impact ceramic rather than resin, raising abrasion and thermal-shock resistance without opening up the film. At 80 plus or minus 2 percent volume solids, very little of the applied wet film is lost to solvent flash-off, so a single 200-250 micron pass builds a genuinely thick, continuous barrier rather than a thin, pinhole-prone one. In an erosion-corrosion setting the two mechanisms reinforce each other, because the coating keeps its barrier integrity precisely where mechanical wear would normally break through and let corrosion start.

Where it is used

• Internal lining of pipelines carrying slurry or gas with a high solids load, where erosion precedes corrosion
• Effluent drainage lines and wastewater treatment channels exposed to abrasive, chemically active flow
• Coke oven gas lines and associated ducting in steel and coke plants
• Structural steelwork needing combined chemical and abrasion protection
• Storage tank linings holding aggressive or particulate-laden media
• Battery storage and acid-handling areas requiring acid-resistant flooring or bunding
• Pulp and paper mill equipment and concrete exposed to wear and chemical wash
• Marine installations and mine infrastructure facing corrosive, high-wear service

Key advantages

• Outstanding abrasion resistance from the ceramic filler, suited to high-velocity particulate flow
• Excellent resistance to both acids and alkalis in one film
• High thermal-shock resistance, useful where surfaces cycle between temperatures
• High volume solids (80 plus or minus 2 percent) build a thick barrier in fewer coats
• Low-VOC system at 150 g/L, easier on enclosed-site ventilation requirements
• Better UV tolerance than a standard amine epoxy thanks to the cycloaliphatic amine cure
• Versatile substrate range: steel, concrete and epoxy mortars
• Applies by brush, roller or airless spray to suit site access and geometry

Limitations & considerations

• Short pot life of about 2 hours at 25 degrees C, so mix only what the crew can apply
• Ceramic fillers settle in the can and affect rheology; both components must be thoroughly power-stirred before and during mixing
• Needs the correct STP primer to perform: ShaliPrime C on concrete, ShaliPrime Zn Ph 60 on metal
• Steel must be prepared to NACE or SSPC standards and concrete must be sound and 28-day cured, which adds preparation time
• Recoat window of 8-16 hours at 25 degrees C must be respected for proper intercoat adhesion
• Pot life, cure and recoat times all shift with ambient temperature and need adjustment on hot or cold Indian sites

How we position STP ShaliKote C

ShaliKote C sits at the abrasion-heavy end of STP’s protective coatings line. Pair it with its own system primers, ShaliPrime C for concrete and ShaliPrime Zn Ph 60 for metal, to get the rated performance. Where the dominant threat is immersion in aggressive chemicals rather than particle erosion, STP’s chemical-resistant novolac and vinyl ester linings are the better call, and for straightforward corrosion protection of structural steel a standard STP epoxy-polyurethane system is more economical. Across our other brands, specifiers who want a broad-spectrum immersion-grade barrier often look at Fosroc’s Nitocote EN901 epoxy novolac, while Sika and MC-Bauchemie offer comparable protective-coating ranges we also supply. Space Arc can map the right primer, coating and topcoat stack to your exposure profile.
