By leveraging its partners’ collective expertise and advanced technologies, the Alliance will drive sustainable practices within the composites industry.

Alan Harper Composites specializes in reusable silicone technology for composite molding. With more than 15 years of experience, the company offers an extensive range of products, including molding supplies, silicone spray machinery, high-quality platinum cure silicone and training.
