Sun John Corporation

Sun John Corporation was established in ***8 and has been a manufacturer of asphalt roofing felts until ***5. From the very beginning, we have been determined to play a leadership role in the field of waterproofing materials, so in ***7 we set up a new production line for self-adhesive waterproofing membranes. In the recent years, we have broadened our scope to include other special purpose membrane systems and coating systems. We strive to meet customer needs and, with our experienced technicians, our broad line of high performance and premium grade waterproofing membranes is always able to respond to particular requirements. Our own in-house research and development laboratory continues to play a key role in keeping us and our production lines on the leading edge of technology.
