HITEK 325

HIGH-TEMPERATURE PAINT (2000°F-2500°F)

Hitek 325 is a premium one-component, silicon-based, high-temperature resistant coating formulated to withstand continuous exposure to extreme temperatures up to 2500°F. It is specially engineered for chimneys, boilers, incinerators, exhaust stacks, and other metal surfaces operating under intense heat stress.

This coating delivers long-term protection against oxidation, scaling, and corrosion on high-heat industrial equipment. Hitek 325 forms a durable, heat-cured film that resists cracking and flaking, even after prolonged thermal cycling.

Product Overview

Hitek 325 offers exceptional thermal resistance and corrosion protection in the most demanding industrial environments. Its silicon-based formula creates a heat-stable barrier that adheres strongly to properly prepared metal surfaces.

Key Features:

  • Withstands temperatures up to 2500°F

  • Silicon-based formulation for superior heat stability

  • Single-component system – no mixing required

  • Ideal for chimneys, boilers, kilns, incinerators, and high-temp process equipment

  • Excellent resistance to oxidation, corrosion, and thermal shock

  • Quick-drying and easy to apply by spray, brush, or roller

  • Long-lasting performance in industrial and marine environments

Application Guide

Surface Preparation:

  • For Best Results: Perform abrasive blasting to SSPC-SP 10 (Near-White Metal Blast Cleaning) to remove rust, scale, and old coatings. This ensures proper surface profile and adhesion.

  • Alternative (If Blasting Is Not Feasible): Use mechanical surface preparation such as power tools (grinders, needle scalers) to meet SSPC-SP 11 standards (Power Tool Cleaning to Bare Metal).

  • Ensure the surface is completely clean, dry, and free of dust, oil, and grease before application.

  • For rust-prone or severely corroded areas, prime with Coatguard 220 Zinc-Rich Primer to enhance corrosion resistance.

Application:

  • Apply only on clean, dust-free, and dry metal substrates.

  • Use brush, roller, or air/airless spray.

  • Avoid over-application to prevent sagging or uneven thickness.

  • Ensure uniform coverage for optimal thermal protection.

  • No mixing required, but stir thoroughly before application.

Curing:

  • Allow drying at ambient conditions before exposure to high temperatures.

  • Full curing is achieved through gradual heat exposure during equipment start-up.

System Use

High-Temperature Coating System for Metal Surfaces

This coating system is designed to protect metal substrates in extreme heat conditions. Each layer serves a specific role in ensuring long-term performance and durability in industrial environments.

Layer 1: Coatguard 220 – Zinc-Rich Primer

Coatguard 220 is a high-performance zinc-rich epoxy primer used to provide long-term corrosion protection through sacrificial cathodic action.

  • Function: Creates a protective base that inhibits rust formation and strengthens adhesion for subsequent coatings.

  • When to Use: Especially recommended in high-rust areas or marine-influenced environments.

  • Drying Time: Allow the primer to fully cure before applying the topcoat. Surface must be clean, dry, and dust-free.

Layer 2: Hitek 325 – High-Temperature Resistant Topcoat

Hitek 325 is a one-component, silicon-based paint designed for surfaces exposed to extreme temperatures up to 2500°C.

  • Function: Acts as the final protective layer, resisting thermal shock, oxidation, and long-term heat exposure.

  • Application: Apply using a lint-free high tensile roller, brush, air spray, or airless spray. Avoid over-rolling to prevent lap marks.

  • Coats Required: Typically 1–2 coats depending on the design specification and exposure conditions.

  • Recoat Interval: Recoat after 4 hours or as needed based on environmental conditions and film build.

This system is ideal for use on boilers, furnaces, chimneys, incinerators, and high-temperature ducts, ensuring reliable performance even under continuous high-heat operations common in Philippine industrial settings.
