India’s construction industry is one of the world’s largest and fastest-growing — consuming vast quantities of industrial chemicals for site maintenance, building material manufacturing, surface treatment and structural repair. From construction contractors managing large infrastructure projects to wall putty manufacturers and building material suppliers — the demand for reliable, cost-effective industrial chemicals in bulk is enormous.
Orbit Chemicals, Kishangarh supplies three core product categories to the construction industry: industrial rust remover chemical, high-whiteness marble powder and polyester resin systems. All three are available in bulk B2B quantities with pan-India delivery from our Kishangarh, Rajasthan manufacturing facility.
Product 1: Industrial Rust Remover Chemical (RR) — Bulk Supply India
Rust is one of the most pervasive and costly problems facing the construction industry across India. Construction machinery, scaffolding, rebar, hand tools, formwork steel, cranes, excavators and storage facilities all develop rust — particularly during and after monsoon season when India’s humid climate dramatically accelerates corrosion.
Untreated rust causes progressive structural weakening, equipment failure, safety hazards, aesthetic damage and — critically — when rebar in reinforced concrete corrodes, it can compromise the structural integrity of buildings and infrastructure over time.
How Rust Remover Chemical (RR) Works — Phosphoric Acid Chemistry
Orbit Chemicals’ Rust Remover (RR) is a phosphoric acid-based industrial rust remover formulated for construction industry use. Unlike simple acid rust dissolvers, phosphoric acid rust removers work through chemical conversion — they convert iron oxide (rust, Fe₂O₃) into iron phosphate, a more stable compound that:
- Stops further rust progression
- Provides a mild protective layer on the treated metal surface
- Does not aggressively attack the underlying base metal
- Can be neutralised and painted/coated over after treatment
Construction Industry Applications
- Rebar treatment — Remove surface rust from rebar before concrete pouring to ensure proper bonding and prevent rust staining in concrete
- Construction machinery maintenance — Regular treatment of excavators, cranes, concrete mixers, pumps and other equipment to extend operational life
- Scaffolding and formwork — Maintain scaffold poles and steel formwork in reusable condition
- Steel structure treatment — Pre-painting rust removal on structural steel columns, beams and purlins
- Tool and equipment maintenance — Hand tools, cutting blades, trowels and other construction tools
- Site infrastructure — Water pipes, gate frames, storage tanks and site facilities
Step-by-Step Application for Construction Use
- Surface cleaning: Remove loose rust scale, mud, concrete splatter and grease with wire brush or cloth. The chemical works best on clean surfaces.
- Application: Apply Rust Remover (RR) directly to rusted surfaces using brush, spray or by soaking small parts. For heavy rust: apply undiluted. For maintenance/light rust: dilute 1:1 with water.
- Dwell time: Allow 15–30 minutes for moderate rust; 45–60 minutes for heavy corrosion. You will observe colour change from orange-red rust to grey-black iron phosphate.
- Scrubbing: For heavy rust accumulation, use stiff wire brush during or after dwell time to remove loosened scale.
- Rinsing: Rinse thoroughly with clean water after treatment.
- Coating: Apply paint, epoxy primer or protective oil within 24 hours to prevent re-rusting.
Safety Note: Wear chemical-resistant gloves and eye protection when handling concentrated Rust Remover (RR). Avoid use on aluminium, zinc or galvanised metal surfaces — phosphoric acid attacks these metals. Keep away from electrical components during application.
Bulk Supply for Construction Contractors
Rust Remover (RR) is available from Orbit Chemicals in 5L, 20L, 200L drum and bulk tank supply. For large construction contractors, we recommend setting up a quarterly bulk supply agreement to ensure consistent availability during active construction season.
Product 2: Marble Powder — Bulk Supply for Construction & Building Materials
Marble powder (also called marble dust or calcium carbonate powder) is one of the most widely used industrial minerals in India’s construction and building materials sector. Sourced from premium Kishangarh white marble, our marble powder is used across multiple construction applications.
Why Kishangarh Marble Powder Stands Out
Kishangarh is the world’s largest marble processing hub — which means marble powder sourced here comes from the purest, highest-whiteness marble in India. Key quality parameters of Orbit Chemicals marble powder:
- Calcium carbonate (CaCO₃) purity: above 95%
- Whiteness: above 92% (Ry)
- Moisture content: below 0.5%
- Available mesh sizes: 100, 200, 300 and 400 mesh
- Consistent particle size distribution in every batch
Construction Industry Uses of Marble Powder
1. Wall Putty Manufacturing
Marble powder is the primary filler ingredient in cement-based and polymer-modified wall putty — the smooth white coating applied to interior walls before painting. The fine particle size and high whiteness of marble powder contribute to:
- Smooth, paintable surface finish
- High initial whiteness and brightness of the putty
- Better adhesion to cement and plaster substrate
- Improved scrub resistance of the finished putty coating
- Lower cost per unit of coverage compared to alternatives
2. Texture Paints and Exterior Coatings
In decorative texture paints and exterior wall coatings, marble powder provides the textural character, brightness and opacity that define the product’s performance. Different mesh sizes create different surface texture effects — coarser grades for rough texture, finer grades for smooth or semi-textured finishes.
3. Cement and Concrete Additive
At low replacement levels (5–15% of cement weight), marble powder improves concrete workability, reduces water demand and slightly improves early compressive strength. Used in precast concrete and decorative concrete products.
4. Floor Screeds and Repair Mortars
In polymer-modified floor screeds and repair mortars, marble powder improves surface hardness, reduces shrinkage and enhances the cosmetic finish of the cured mortar surface.
5. Paint Industry — Extender Filler
The paint manufacturing industry is a major consumer of marble powder as an extender filler — reducing the required quantity of expensive titanium dioxide (TiO₂) while maintaining brightness and opacity in interior emulsion paints.
Marble Powder Packaging and Bulk Supply
Orbit Chemicals marble powder is available in:
- 25 kg HDPE bags (standard)
- 50 kg HDPE bags (for larger buyers)
- Bulk loose supply for buyers with bulk handling silos
Competitive bulk pricing with pan-India delivery from our Kishangarh facility. Construction material manufacturers, wall putty producers and paint manufacturers in Rajasthan, Gujarat, Maharashtra and Delhi NCR are among our regular marble powder buyers.
Product 3: Polyester Resin & Catalyst System — Construction and Building Use
The construction industry uses polyester resin in multiple applications — from bonding stone cladding and decorative elements to manufacturing fiberglass reinforced plastic (FRP) panels used as wall cladding, roofing sheets and structural components in industrial buildings.
Construction Applications for Polyester Resin
- FRP roofing sheets and wall cladding — Used extensively in industrial and commercial buildings as lightweight, corrosion-resistant alternatives to metal sheets
- Decorative stone cladding bonding — Polyester resin used to bond thin stone veneers and cladding to building facades
- Anchoring systems — Resin anchors for fixing bolts and fittings in masonry and concrete
- Surface coating and protection — Protective coatings on concrete surfaces in industrial facilities
- Repair mortars — Polymer-modified repair compounds for concrete spalling and surface defects
Recommended Polyester Resin Grades for Construction
- Yellow PA Polyester Resin — Cost-effective industrial grade for non-colour-sensitive construction applications. High reactivity, good mechanical properties.
- White Polyester Resin — All Grades — For applications requiring white appearance — decorative FRP panels, stone bonding, repair compounds visible in finished work.
- MEPK Hardener + Cobalt Accelerator — Complete catalyst system for polyester resin curing. Available in all standard concentrations for ambient temperature cure in Indian climate conditions.
Temperature-Adjusted Dosing for Indian Climate
This is critical for construction site use where temperature varies dramatically between seasons and regions. Orbit Chemicals provides climate-adjusted dosing recommendations for our catalyst system:
- Summer (above 30°C): Reduce cobalt to 0.1–0.15%, MEPK to 1–1.2% — prevent premature gelling
- Monsoon season (high humidity): Standard dosing but increase cobalt slightly — humidity slows surface cure
- Winter (below 18°C): Increase cobalt to 0.3–0.4%, MEPK to 1.8–2% — ensure adequate cure at low temperatures
Product 4: Epoxy Resin for Structural Repair and Crack Filling in Construction
Beyond marble processing, epoxy resin plays an important role in construction — for structural crack filling in concrete, stone and masonry, for anchoring systems and for bonding structural elements. Orbit Chemicals supplies several epoxy grades relevant to construction use:
- Orbit Epoxy Crack Filler ORB 330 — Low-viscosity crack filler for concrete and stone structural cracks
- Orbit Epoxy 25 — General crack filling grade for construction stone and concrete repair
