Collinite No. 900 Paste Mold Release: Industrial-Grade Performance for Fiberglass Fabrication
When it comes to surface protection and release chemistry, few names carry the weight of Collinite. Founded in 1936 by Charles H. Collins and his son Chuck, Collinite has built its reputation on creating top-quality wax products using premium ingredients. That same no-compromise philosophy that drives their legendary automotive and marine waxes extends directly into their mold release products — most notably the Collinite No. 900 Paste Mold Release.
What Makes the Collinite No. 900 Stand Apart
This highly versatile mold release paste is designed for manufacturers who require the best, and it has been extensively tested and approved by the world's largest fiberglass manufacturers in molding processes, both filled and unfilled, with and without gelcoat. That breadth of approval across so many different process types is a testament to the formula's reliability and adaptability on the shop floor.
The No. 900 is used extensively for normal hand lay-up and spray-up molding in the manufacture of fiberglass boats. Whether you're pulling complex hull shapes or flat panel sections, the paste-type consistency delivers consistent, even coverage — a critical factor when mold integrity and part quality are on the line.
Ease of Use Without Sacrificing Durability
One of the most practical advantages of the Collinite No. 900 is its application simplicity. Professionally formulated for durability, it requires no hard rubbing or machine buffing and is suitable for both normal hand lay-up and spray-up molding. For production environments where time and labor are closely managed, a release agent that performs without the need for power tools or extensive manual effort is a genuine operational advantage.
Collinite still does it the right way — in the small rust-belt city of Utica, NY, with hands on the products and feet firmly on the ground. That hands-on, small-batch mindset means every can of No. 900 reflects the brand's commitment to consistent, professional-grade results.
Built for Professionals, Trusted by Industry
Extensively tested and approved by the world's largest fiberglass manufacturers in molding processes — both filled and unfilled, with and without gelcoat — the No. 900 is designated for professional use. It fits naturally into the workflows of boat builders, composite fabricators, and anyone working with fiberglass layup operations who demands clean, reliable part release every time.
Collinite's reputation has spread not through mass marketing but by word of mouth from satisfied customers, and by consistently offering superior products, Collinite has weathered many changes in industry trends while their formulas remain among the best on the market. The No. 900 Paste Mold Release is a prime example: a straightforward, proven product trusted by professionals who can't afford mold failure on the production line.
