Spray polyurea elastomer waterproof coating

1.Product Introduction

Polyurea waterproof coating is a new type waterproof coating which a lot of advantages. Its main properties are as following:

Low VOC content, nearly 100% solid contentFast curing, no flowing phenomenon, can be easily applicable on curved, inclined and vertical surface etc.Not sensitive to water and moisture, not influenced by environment and moisture when applied waterproof coating.Thickness can be from 100μm to several cm, preventing from repeated applicatioin problem.High physical properties, such as tensile strength, elogation, abrasive resistance, anti corrosion ability.Long term of heat stability under 120°C, can bear short term of 150°C impact.Various colors availableHardness from Shore A30 to Shore D65
