INTERCURE 200 PART A INDIVISIBLE KIT

What is Intercure 200 Part A and why choose it?

Intercure 200 Part A is the base component of a two-component rapid recoat epoxy primer, based on zinc phosphate and micaceous iron oxide and formulated with proprietary polymer technology. When correctly mixed with its curing agent (Part B) it provides a high-solids, low-VOC protective primer for steelwork, designed for fast curing and overcoating even at low temperatures.

This system is intended for demanding protective coating projects where productivity and corrosion protection are both critical. It is suitable for use as a shop or site primer, with overcoating typically possible within 3 hours in most climates, helping to speed up fabrication and maintenance schedules.

Main features

• Two-component rapid recoat epoxy primer: Part A is mixed with Part B in a 3:1 volume ratio to create a high-performance epoxy coating.
• Fast cure and overcoating: Overcoatable within 1–3 hours in typical temperatures (see drying schedule), supporting high throughput in fabrication shops and rapid maintenance work on site.
• Performs at low temperatures: Designed to cure and be overcoated rapidly even under low temperature conditions; capable of curing below 0°C, with application restrictions (see below).
• High solids, low VOC: 67% volume solids with VOC values of 2.67 lb/gal (320 g/L) by EPA Method 24, 213 g/kg (EU Solvent Emissions Directive) and 297 g/L (Chinese National Standard GB23985).
• Robust anti-corrosive pigmentation: Zinc phosphate and micaceous iron oxide pigmentation for long-term steel protection in aggressive environments.
• Good film integrity over time: At 75 microns dry film thickness, the coating can typically be overcoated after up to 6 months’ exposure, provided it is properly cleaned and any mechanical damage repaired.
• Versatile application methods: Can be applied by airless spray, conventional air spray, brush or roller.
• Low temperature and chemical service suitability: Preferred in systems for chemical environments where zinc-rich materials may be attacked in acidic or alkaline conditions.
• System compatibility: Compatible with a wide range of recommended primers and topcoats/intermediate coats from the International Protective Coatings range.

Product characteristics and limitations

• Preferred for use in chemical environments where zinc-rich materials may be attacked in acidic or alkaline conditions.
• Over-application should be avoided; excessively thick films may reduce topcoat adhesion after ageing and may suffer cohesive film splitting if subsequent coats are also over-applied.
• Capable of curing at temperatures below 0°C (32°F), but should not be applied below 0°C (32°F) where ice formation on the substrate is possible.
• Only thin with recommended International GTA thinners; alternative thinners, especially those containing ketones, can severely inhibit curing.
• Not available in pale and pastel shades due to rapid discoloration; like all epoxies, it will chalk in exterior exposure. These effects do not impair anti-corrosive performance.
• In C1 and C2 corrosive environments (ISO 12944), small damaged areas and welds may be repaired by hand or power tool cleaning.
• Not intended as a primer for steelwork subjected to immersion conditions.
• Can be used as a primer on suitably prepared alternative substrates such as stainless steel and alloys (subject to International Protective Coatings guidance).
• Absolute adhesion of topcoats to aged Intercure 200 is lower than to fresh material but adequate for the specified end use.
