Non Sparking Putty Knife by Pahwa MetalTech

Safe Gasket Scraping and Surface Preparation in Hazardous Plant Areas

Pahwa MetalTech's Non Sparking Putty Knife is precision-engineered for reliable, spark-free performance in the most demanding hazardous environments. Compliant with ATEX, EN, and IS standards, these tools eliminate ignition risk in oil and gas, petrochemical, pharmaceutical, mining, and explosives industries. Every tool is quality-inspected for dimensional accuracy, alloy integrity, and functional performance before delivery, ensuring Zone 0, Zone 1, and Zone 2 classified area compliance throughout service life.

Non Sparking Putty Knife

Material : 

Pahwa MetalTech's Non Sparking Putty Knife is available in two premium non-sparking alloys: QTi® (Copper Titanium) and BronAL® (Aluminium Bronze).

QTi® offers superior hardness and tensile strength for heavy-duty applications, with a longer service life than conventional beryllium copper.

BronAL® delivers excellent corrosion resistance, ideal for marine, chemical, and humid environments. Both alloys comply with ATEX, EN, and IS non-sparking tool certifications and are non-magnetic, ensuring safety in Zone 0, Zone 1, and Zone 2 classified areas. Material test reports and special certifications are available on request.

Size and Range : 

Pahwa MetalTech offers the Non Sparking Putty Knife in the following specifications: Type A and B; 25mm to 65mm blade width; 200mm blade length.

The range covers the most common operational requirements for hazardous area maintenance.

All sizes are manufactured to precise tolerances for reliable fit and performance. Custom sizes and configurations beyond the standard range are available on request for specific site requirements or OEM applications. Contact Pahwa MetalTech for custom configuration enquiries.

Applications :

Pahwa MetalTech's Non Sparking Putty Knife is used across critical hazardous industries.

Petrochemical gasket removal, oil refinery flange face cleaning, classified spray paint areas, pharmaceutical equipment cleaning and sealing, chemical plant gasket replacement, and classified zones where scraping, spreading, or applying sealants must be done without spark.

In all these applications, QTi® and BronAL® non-sparking alloys eliminate ignition risk from tool-to-surface contact, protecting personnel, equipment, and facilities. These tools help operations teams comply with OISD, PESO, ATEX, and other international safety frameworks governing classified zones.

Do's

  • Select the blade width that matches the joint or gasket surface being worked — a blade too wide flexes and reduces control.
  • Hold the putty knife at a low angle (15–20°) for spreading sealant to achieve a thin, even film without buildup.
  • For gasket removal, drive the blade under the gasket at the edge using short controlled strokes — avoid gouging the flange.
  • Use the stiff Type A blade for scraping hard deposits and the flexible Type B blade for spreading and finishing.
  • After spreading sealing compounds, clean the blade immediately — cured sealant is very difficult to remove and reduces flexibility.
  • Apply a light coat of release agent to the blade before using it with adhesive-backed gasket materials.
  • Check the blade-to-handle joint for security before each use — a loose blade can separate from the handle mid-scrape.
  • Store putty knives flat in a tool roll — blades stored on edge develop permanent curvature that distorts spreading work.

Donts

  • Never use a steel putty knife in a classified zone — the blade contacts the metal flange face and can generate sparks.
  • Do not use the putty knife blade as a screwdriver, chisel, or pry tool — the thin blade will bend and snap.
  • Avoid applying lateral bending force to the blade — putty knives transmit pushing and pulling loads, not lateral loads.
  • Do not use the putty knife on flange faces that are live or under pressure — always depressurise before gasket work.
  • Never hold the blade with bare hands during a gasket removal stroke — the blade edge can cut fingers if it slips.
  • Do not use a bent or kinked blade for precision spreading — the deformation transfers to the sealant layer.
  • Avoid using the putty knife to remove cured two-part epoxy or structural adhesive without solvent pre-treatment.
  • Do not use the putty knife blade on glass-reinforced or composite surfaces — blade contact can fracture the surface gel coat.
