GP-MAC Polymer Modified Bitumen Waterproof Coating (Liquid Waterproof Membrane)

The polymer-modified bitumen waterproof coating (liquid waterproof membrane) and the water-based bituminous waterproof coating (JC/T408) are a type of water-based waterproof coatings. They are made by emulsifying road bitumen with grease, and then fully mixing it with water-based emulsions, additives, etc. through special equipment.

Product Characteristic

●Cold construction, which is safe and convenient. It can be constructed on wet substrates and has excellent adhesion to concrete, wood and asbestos boards.
●It has excellent low-temperature elongation performance, can adapt to the deformation of the substrate, and ensures the waterproof quality of the project.
●It is resistant to high temperatures, corrosion and aging.

Product Classification

Type: The product is classified into Type L and Type H according to its performance.

Product Apperance

Stir evenly and no color difference, no gel formation, no caking, and no obvious bitumen filaments.

Application Scope

It is suitable for waterproofing and moisture - proofing projects of roofs, walls, floors, basements, cold storages, and cavities, as well as seepage prevention, caulking and anti - corrosion projects of reservoirs and pipelines. It can also be used for the repair of old roofs and other waterproofing projects.

Package, Storage and Delivery

●This product is packaged in plastic barrels, with each barrel weighing 20 kg.
●The product should be protected from exposure to the sun and rain, and good ventilation should be ensured. The storage temperature should be between 5°C and 40°C.
●The water-based bituminous waterproof coating is non-flammable and can be transported in the general way. The temperature during transportation shall not be lower than 0°C. Keep it away from heat sources, prevent collisions, and ensure the packaging is intact.
●Under normal transportation and storage conditions, the shelf life is six months from the date of production.
