YZ 8212 butyl waterproof tape aluminum foil on one side with a smooth appearance due to the use of aluminum foil substrate and has a strong bond of butyl rubber, but also has excellent weather resistance, aging resistance and water resistance of the sticky surface sealing, protection and so on. Because it is completely free of solvents, so I do not shrink, not curing, not crack, does not emit toxic gases; so the sticky surface thermal expansion and mechanical deformation has excellent conformability, is an advanced waterproof seal materials are mainly used in steel gutters, color plates and concrete walls and metal roofing connection, car repair and other parts of the leakage. 1. Features 1) can remain permanently flexible, able to withstand a certain degree of displacement. 2) Excellent water tightness and resistance to chemical corrosion, UV (sunlight) capability; more than 20 years of life. 3) Easy to use, the amount of accurate, cost-effective Excellent. 2, the construction method 1) must be completely removed before the water plate surface, oil, dirt, dust and other impurities and repair on the sticky surface of silica gel, a special organic solvent cleaning available, such as when you must use water to clean sticky surface before pasting completely dry before construction; 2) depending on the gap, joint width, use different specifications of the tape, the first tear isolated on the use of paper tape, taped or cracks along the wiring at; 3) while pasting hand or rolling back of the small, hard roll tape, so that the surface is sufficiently sticky paste to ensure that the surface sticky tape and are closely integrated. 3, the main technical indicators Item Unit detected values ??essential component of butyl rubber-component low temperature flexibility -40 ℃ no crack tack holding the ball through the humidity 13.5 g / m 0 aging 2000H 68 ℃ surface without discoloration, hardening, turtle Temperature -40-90 ℃ crack peel strength aluminum N / cm 14.3 color plate N / cm 17.7 cement mortar boards N / cm 16.5 copper N / cm 15.6 glass N / cm 14.8 Notes: 1) In addition to the low temperature flexibility, more Other performance testing conditions for 23 ℃. 2) The product life of more than 20 years, with anti U.V100 hours for one year. 4, packaging cartons, packaging according to customer requirements 5, color black, gray, white, or 6, storage and expiration date should be stored at 27 ℃ in a cool dry place below the other colors according to user requirements, since the date of production, storage period of 12 months. 7, note 1) Please be sticky sheet surface water, oil, dust and other dirt removal before use. 2) the tape should be stored in a cool dry place, away from heat, direct sun or rain. 3) The product is a self-adhesive materials, once pasted in place to achieve the best waterproof effect.
