As an authorized supplier in Pune, Shree Paint & Coating Industries provides prompt supply, technical data sheets (TDS), and specification guidance for all Sigma Coating systems across Maharashtra.
Intermediate coatings form an important layer in a protective coating system. They help build the required film thickness and improve the overall protection of surfaces exposed to demanding industrial environments.
Epoxy intermediate coatings provide an additional protective layer between the primer and finish coat. They help improve the durability and overall performance of the coating system.
High-build epoxy coatings are designed to provide greater film thickness with fewer coats. They help protect surfaces exposed to harsh industrial conditions.
MIO (Micaceous Iron Oxide) epoxy coatings contain special mineral pigments that help create a protective barrier against moisture and environmental exposure.
Zinc phosphate epoxy coatings combine epoxy resin technology with corrosion-inhibiting pigments to protect prepared metal surfaces.
Barrier coatings help limit the penetration of moisture and other corrosive elements into the coated surface. They are used as part of protective coating systems in demanding environments.
Polyurethane finish coatings provide an attractive topcoat with good gloss, colour retention and resistance to outdoor exposure. They are commonly used where both appearance and long-term surface protection are important.
Two-component polyurethane coatings are formulated using a base and hardener that react to form a durable protective finish.
High-gloss polyurethane coatings create a smooth and shiny finish while helping protect the underlying surface.
Semi-gloss polyurethane coatings provide a balanced finish with moderate shine and a professional appearance.
Weather-resistant polyurethane coatings are designed for surfaces exposed to sunlight, rain and changing outdoor conditions.
Selected polyurethane finish systems are designed to withstand exposure to specific chemicals and industrial contaminants.
Epoxy finish coatings provide a durable protective layer for surfaces exposed to mechanical wear, moisture and selected chemicals. They are suitable for industrial applications where long-lasting protection is required.
Epoxy finish coatings provide a protective and decorative finish for prepared metal and concrete surfaces.
High-build epoxy finishes are designed to create a thicker protective coating layer, helping protect surfaces in demanding service conditions.
Chemical-resistant epoxy coatings are developed to protect surfaces exposed to specified chemicals, oils and industrial substances.
Glass-flake epoxy coatings contain specially selected glass flakes that create a strong barrier against moisture and corrosive substances.
MIO epoxy finishes use micaceous iron oxide pigments to improve barrier protection and provide a durable coating finish.
Alkyd coatings offer a smooth and attractive finish for suitable industrial and metal surfaces. They are commonly selected for general-purpose applications where ease of application and good appearance are important.
Synthetic alkyd coatings provide a protective decorative finish for general metal and industrial surfaces.
High-gloss alkyd coatings provide a shiny finish that enhances the appearance of painted surfaces.
Industrial enamel coatings provide a decorative and protective finish for suitable industrial surfaces.
Quick-drying alkyd coatings are designed to reduce waiting time between application and handling, subject to recommended conditions.
Polysiloxane coatings are high-performance finishes designed for demanding environments where weather resistance, colour retention and long-term durability are important.
High-performance polysiloxane coatings provide a durable finish for structures exposed to challenging outdoor and industrial conditions.
Weather-resistant polysiloxane coatings help maintain the appearance of surfaces exposed to sunlight, rain and changing weather conditions.
Corrosion-protective polysiloxane systems are used as part of suitable protective coating systems to help protect steel structures in demanding environments.
Surface-tolerant epoxy coatings are designed for maintenance situations where complete surface preparation may be difficult. They can be suitable for properly assessed surfaces where conventional coating preparation is challenging.
Surface-tolerant epoxy primers are designed to provide adhesion and corrosion protection on suitably prepared surfaces, including certain aged or previously coated substrates.
These coatings provide an additional protective layer in maintenance coating systems where surface conditions and preparation requirements need special consideration.
Maintenance epoxy coatings help restore and protect existing surfaces that require repair or recoating.
Heat-resistant coatings are specially developed for equipment and structures that operate at elevated temperatures. They help protect surfaces while maintaining coating performance under the specified temperature conditions.
Aluminium-pigmented heat-resistant coatings are designed for suitable metal surfaces exposed to elevated temperatures.
Silicone-based coatings are developed for applications that require resistance to higher operating temperatures.
Thermal protective coatings are used on suitable equipment and surfaces where protection against heat exposure is required.
Tank lining systems are designed to protect the internal surfaces of storage tanks and vessels from corrosion and contact with stored materials. The correct lining depends on the tank contents, operating temperature and service conditions.
Epoxy tank linings create a protective internal coating that helps prevent corrosion and protect tank surfaces.
Chemical tank linings are developed for storage vessels that come into contact with specified chemicals and industrial liquids.
Solvent-resistant lining systems are designed for tanks and vessels that store or handle compatible solvents.
Food-contact tank linings are designed for suitable storage applications where the lining must meet the required food-contact standards.
Fresh water tank linings help protect the internal surface of tanks used for storing water. Product selection should be based on the relevant potable-water or water-contact approval.
Cargo tank linings are designed to protect tanks used for transporting or storing specific cargo materials.
Road marking coatings help create clear and visible traffic guidance for drivers and pedestrians. They are used to identify lanes, crossings, parking spaces and other important road safety markings.
Thermoplastic road marking materials are applied in a heated state and form durable markings after cooling.
Water-based road marking coatings provide a practical solution for marking suitable road and traffic surfaces.
Reflective road markings use suitable reflective materials, such as glass beads, to improve visibility under vehicle headlights.
