GWIPPO Glass-Lined Cover Coating has become a trusted porcelain enamel coating solution for chemical equipment protection worldwide, supported by four key advantages:
With over 35 years of experience in enamel technology and 30 years of glaze formulation expertise, GWIPPO is supported by a professional technical team with deep knowledge of glaze application processes and on-site operation.
Our cover coat offers excellent resistance to explosion, chipping, high temperatures, and strong acid and alkali corrosion. It is widely applied in glass-lined reactors, storage tanks, agitators, and other chemical equipment, significantly extending service life and operational reliability.
Using scientifically optimized formulations and electric furnace melting technology, the glaze is processed into uniform flakes through precise and controlled production procedures, ensuring stable quality and consistent performance.
GWIPPO provides comprehensive global service support, including free enamel firing guidance and 24/7 emergency technical assistance, ensuring reliable performance throughout the equipment lifecycle.
Glass-lined equipment is suitable for most chemical media except phosphoric acid containing fluoride ions when the operating temperature is ≥ 180℃ and the fluoride ion volume fraction is ≥ 30%.
For alkaline media, the appropriate glaze type should be selected based on specific operating parameters, including reaction temperature, alkali concentration, and pH range.
Glaze types such as GP-10#, GP-21#, and GP-26# demonstrate excellent alkali resistance and are commonly recommended for alkaline applications.
GP-16# glass-lined agitator enamel frit offers excellent resistance to both acids and alkalis, along with a relatively high thermal expansion coefficient. This makes it particularly suitable for externally enameled components such as stirrers, nozzles, and accessories.
For operating temperatures approaching 200℃, GP-12# Enamel Frit is recommended due to its excellent high-temperature stability and reliable performance under elevated thermal conditions.
