PUA series drinking water grade polyurea

Product Overview

Ruitu Technology PUA series drinking grade polyurea is the third-generation polyurea product newly developed by Qingdao Ruitu New Material Technology Co., Ltd. The material is a two-component product composed of semi prepolymer, polyether, filler, pigment and other raw materials, with a 100% solid content. It is sprayed into a film on site by a two-component high-pressure spraying equipment. This coating does not contain organic solvents and other volatile substances. After curing into a film, its chemical properties are stable and meet the hygiene standards for drinking water. It can be widely used for the protection of internal surfaces of pipelines, containers, etc. involving drinking water.

Technical features

100% solid content, no solvents, safe construction, environmentally friendly.

Fast curing, 40 seconds gel, 10 minutes to reach the initial strength.

Resistant to high temperature softening, the adhesion can still reach over 6Mpa at 80 ℃.

Excellent chemical resistance, able to withstand long-term corrosion from media such as water, seawater, acid and alkali salts.

Excellent adhesion on steel substrates.

application area

Ruitu Technology's PUA series of drinking water grade polyurea polyurethane coatings can be widely used for anti-corrosion protection of various types of drinking water pipelines and steel structures, such as drinking water pipelines, seawater desalination pipelines, and seawater desalination devices.

★ Drinking water pipeline

★ Municipal water supply pipeline

Theoretical dosage

The recommended film thickness is about 1.0-2.0mm, and the estimated consumption is 1.5-2.5kg/m2. The consumption at nodes, corners, and certain special areas may be too high compared to the theoretical consumption.
