ACST CHEMICAL in China has more than 15 years experience in manufacturing high quality waterproof sealing products, including butyl tapes and sealants. We manufacture both double-sided and single-sided butyl tape (with aluminum, non-woven, PE, EPDM and EPR backing).Different sizes, shapes and colors (grey, white, black and etc). Anti-mildew bathroom tape is our special product. We also make butyl / acrylic / neoprene sealant. Our acrylic sealant is water-based and can be a replacement of silicon sealant, but performs much better because it is anti-mildew and environmentally friendly. We have two kinds of butyl sealant, drying and non-drying. The latter is especially for steel construction.
