Waterproof Butyl Sheet

Product Name: DF88-150 Waterproof Butyl Sheet
(Self-adhesive Waterproof Butyl sheet with Steel Plate Inserted)
Patent No. 200820134668.5

General Specification: 4mm*150mm*6m.

1. Features:
(1) It’s a self-adhesive waterproof butyl rubber sheet with a steel plate inserted
(2) Be good at waterproofing and sealing for its high bonding strength.
(3) Easy operated, high tensile strength and non-curing lifelong.
(4) Do well in following and adapting to the interfaces of cracks and deformations.
(5) It has excellent resistance to chemical, corrosion and weather.
(6) There is no flowing at 90 degrees Celsius and no cracking at -40 degrees Celsius.
(7) Odorless, solvent-free and environmentally friendly.

2. Application:
Used in waterproofing and sealing of concrete joints of subways, tunnels, dams, culverts and other underground works, effectively preventing leakages due to structural deformations.

3. Basic Performance:
(1) Appearance: black sheet parceled by release paper.
(2) Density of 1.14 ± 0.1 g//cm3
(3) Heat resistance: 90 degrees Celsius for 2h with no flowing, cracking and deformation.
(4) Low temperature flexibility:-40 degrees Celsius with no cracking.
(5) Water absorption: 168h 23 ± 2 degrees Celsius ≤ 0.3%
(6) Shear force between self-adhesive butyl and steel ≥ 11N/mm
(7) Vertical adhesive strength between waterproof sheet and mortar board ≥ 0.1MPa
(8) Shear force between waterproof sheet and mortar board ≥ 2.5N/mm

4. Using:
Tear off the isolation paper; remove the two release films of faying surface at both ends of the waterproof sheet ( longitudinal lap length 110mm); compact the lap by hand (lap length is 100mm); make the longitudinal center line of waterproof sheet align with the center line of expansion joints and fixed; then fix the model to pull concrete.

Packing: Cartons.
Transportation: Non-hazardous material, transport as general cargo.
Storage: Keep level in a cool and dry warehouse to prevent direct sunlight and keep away from heat. Storage period is six months.
