KF-IM100 Inorganic Zinc Silicate Primer

KF-IM100 inorganic zinc silicate primer uses ethyl silicate hydrolyzate as binder and ultrafine zinc powder as anticorrosive pigment. The coating has a zinc powder content greater than 85%, providing cathodic protection through sacrificial anode action. Temperature resistance 400 degrees. Widely used as heavy-duty anticorrosive primer for offshore platforms/petrochemical equipment/high-temperature pipelines/storage tanks.

ProductsOverview

Inorganic zinc silicate primer is a heavy-duty anticorrosive coating designed by KeXin New Material according to ISO 12944 standards. It is scientifically formulated with high-quality resin and high-performance anticorrosive pigments, featuring excellent anticorrosion performance and adhesion. Widely used for protective coating in heavy-duty anticorrosion fields such as steel structures, bridges, petrochemicals, and ships.

The product has passed rigorous salt spray testing (>1000h) and adhesion testing (>5MPa), and with a complete base-intermediate-topcoat system, it can provide long-lasting protection for 15-25 years. Kexin provides free coating design solutions and technical support services.

CoreAdvantages

Ethyl silicate inorganic bonding · Zero VOC

Ethyl silicate hydrolyzes and polycondenses to form a Si-O-Si three-dimensional inorganic network. The coating VOC is less than 50g/L, approaching zero VOC. The inorganic binder is UV-resistant, high-temperature resistant up to 400 degrees, and solvent-resistant. The standard primer for offshore platforms and petrochemical high-temperature equipment.

Greater than 85% zinc powder · Strongest cathodic protection

The dry film zinc powder content of the coating is greater than 85%, higher than epoxy zinc-rich. The high zinc powder content ensures good electrical contact between zinc particles and between zinc particles and steel. The sacrificial anode protection effect is stronger and more durable than epoxy zinc-rich. Salt spray greater than 2000h.

Validated on offshore platforms and petrochemical installations

Norwegian North Sea offshore platform inorganic zinc silicate primer verified for over 30 years. Petrochemical high-temperature pipeline 400 degrees inorganic zinc primer. Ship water tanks and ballast tanks inorganic zinc primer. Heavy-duty anticorrosive primer for all steel structures requiring the highest anticorrosion grade.

ApplicationProcess

1

Surface preparation

Clean substrates thoroughly of oil and rust. Blast steel to Sa2.5. Pre-treat per product spec to keep the substrate clean. Ambient 5-40°C, relative humidity<85%。

2

Primer / pre-treatment

Select the matching primer or pre-treatment per substrate and system. Mix strictly at the stated ratio and control DFT. Proceed after the primer dries; pre-stripe critical areas.

3

Main-coat application

Apply the main coat per the process spec, strictly controlling DFT, temperature/humidity and flash-off to keep the film uniform without sagging or pinholes.

4

Curing process

Cure fully by stoving or by ambient air drying as the product requires. Keep oven temperature uniform within ±5°C and ramp up gradually to avoid coating defects. For ambient-curing grades, ensure adequate ventilation and suitable humidity.

5

Inspection & acceptance

Inspect all parameters: dry film thickness, adhesion, gloss, colour difference and chemical resistance. Full performance testing is carried out against the relevant standards. Only after everything passes are the test report and warranty issued, and the goods are packed and shipped in dust-free conditions.
