Fluorocarbon Membrane Butyl Rubber Waterproof Membrane

Description

Fluorocarbon film butyl rubber waterproof membrane is an environmentally friendly self-adhesive polymer waterproof material composed of a fluorocarbon film, butyl rubber base, and a release liner produced through a special lamination process.

This material combines the excellent weather resistance of fluorocarbon film with the outstanding low-temperature flexibility, adhesion, and water tightness of butyl rubber. It provides superior bonding performance on various substrates, as well as exceptional resistance to aging, weathering, and chemical corrosion.

The membrane offers excellent waterproofing, airtightness, self-healing, and reflective heat insulation properties, making it ideal for a wide range of waterproofing applications—particularly for the repair and maintenance of color steel roofing and other roofing waterproofing projects.

High Weather Resistance: The material features a built-in fluorocarbon coating, providing excellent UV resistance and a maximum outdoor service life of up to 25 years.

High Adhesion Performance: Strong bonding and tensile strength with excellent elongation, making it highly adaptable to interface deformation and cracking.

Superior Barrier Properties: The surface layer allows less than 0.1% UV transmission, reflects over 85% of sunlight, and offers effective thermal insulation.

Corrosion Resistance: The F-C high-bond energy system of the surface layer resists natural chemical corrosion.

Environmental Friendliness: Durable, corrosion-resistant, tolerant to extreme temperatures, non-toxic, odorless, pollution-free, and solvent-free.

Self-Cleaning Ability: Low surface energy and dense structure prevent biological corrosion.

Self-Healing Performance: Maintains long-lasting airtightness and watertightness, protecting the underlying material from environmental damage.
