Product Introduction
Butyl tape, abbreviated as IIR, is an abbreviation for lsobutylene lsoprene rubber. It has good chemical and thermal stability, with the most outstanding being its airtightness and water tightness. Its air permeability is only 1.7 times that of natural rubber and 1.5 times that of styrene butadiene rubber, while its steam permeability is 1.2 times that of natural rubber and 1.4 times that of styrene butadiene rubber
This material, which is difficult for gases to penetrate, is a piece of cake for waterproof sealing. What's even more frightening is its outstanding weather resistance. According to relevant testing data, the base rubber can withstand high temperatures up to 120 ° C and low temperatures up to -40 ° C
The leakage rate of building waterproofing remains high. According to previous surveys conducted by China Building Waterproofing and Zero Point Consulting, the penetration rate is over 90%. Waterproof repair is already a promising blue ocean waterproofing market, but it is soon to become a red ocean market. Even Dongfang Yuhong quickly established a repair department in 2017, and many large enterprises have also set up repair departments to share this big cake. Products that quickly become popular for repair; Acrylic salt, butyl tape.

(2) Sealing and waterproofing treatment of construction joints in subway tunnel structures in municipal engineering.
(3. Air tightness, waterproofing, and shock absorption at the joints of colored profiled boards. Air tightness, waterproofing, and shock absorption at the joints in polycarbonate sheet engineering.).
(4) Adhesive sealing treatment in automotive assembly
(5) Waterproof sealing treatment of joints in steel structure construction
(6) Butyl tape with composite aluminum foil is suitable for waterproof sealing of various civil roofs, color steel, steel structures, waterproofing membranes, PC boards, etc. under sunlight exposure
Construction regulations
general principles
(1) This regulation applies to the sealing and waterproofing engineering of civil structure roofs and metal panel surfaces that use adhesive tape as a supporting material for waterproofing membrane bonding, metal profiled plate bonding, PC board bonding, and other related materials.
(2) When designing or using adhesive tape, it should be done in accordance with relevant regulations or by referring to the company's enterprise standards.
general provisions
(1) Construction needs to be carried out within the temperature range of -15 ° C to 45 ° C (relevant measures should be taken when exceeding the specified temperature range)
(2) The surface of the base layer must be cleaned or wiped clean, kept dry, and free of floating soil and oil stains.
(3) The bonding area must not be torn or peeled off within 24 hours after construction.
(4) Select different types, specifications, and sizes of tape according to actual engineering needs.
(5) Place boxes at a distance of approximately 10CM from the ground, and do not stack more than 5 boxes.
Construction tools
Cleaning tools, scissors, rollers, wallpaper knives, etc.
Usage requirements
(1) The bonding surface is clean and free of oil stains, grey water, and water vapor.
(2) We guarantee the bonding strength at a base temperature of 5 ° C or above, and special production can be carried out in specific low-temperature environments.
(3) When using, peel off the adhesive tape once before use.
(4) Do not use with waterproof materials containing organic substances such as benzene, toluene, methanol, ethylene, silicone, etc.
process characteristics
(1) Construction is convenient and fast. The use should be bonded in place once, and the surface of the base layer should be clean.
(2) The construction environment requires a wide range of requirements. Construction can be carried out normally when the ambient temperature is between -15 ° C and 45 ° C, and the humidity is below 80 ° C, demonstrating strong environmental adaptability.
(3) The repair process is simple and reliable. Just use single-sided tape for the large leakage area.
