At KOYOKAGAKU, we specialize in the production of various adhesive products, with a focus on adhesive tapes related to the construction industry. We prioritize simplicity, convenience, and ease of use by applying advanced technology. As a result, we have developed maintenance tapes that are both strong and gentle. These tapes have thin and flexible substrates that can be torn neatly and beautifully. They adhere tightly even to uneven surfaces, leaving no residue, being resistant to peeling, and offering convenience in usage. Furthermore, we have developed a butyl series of acrylic airtight tapes, primarily using acrylic adhesive. These tapes exhibit superior durability, exceptional tear resistance, and outstanding flexibility. Our airtight tapes are hand-tearable and free from toluene, xylene, and plasticizers, making them safe and environmentally friendly. These products can withstand 50 years within walls without rotting, melting, deforming, or causing any harm, ensuring long-lasting and eco-friendly performance. At KOYOKAGAKU, we strive for 100% quality and 100% customer satisfaction. With adhesive tapes for the construction, industrial, and electronics industries as our core focus, we are committed to working with our customers to develop even better products and provide adhesive tapes that meet their specific requirements in the market.
