Primers and Sealers

Primers and Sealers

Priming serves as a key process to enhance the quality of composite molds and tooling, reducing surface roughness and establishing a consistent surface profile. Whether applied to plugs, masters, or production-grade molds, mold primers not only create a chemical barrier but also provide a glossy finish, ensure vacuum integrity, and establish an optimal bonding surface for semi-permanent sealers and release agents.

Sealers, on the other hand, are meticulously designed to safeguard mold and tooling investments. They seal micro-porosity and condition raw bonding sites on various substrates, including Class A tooling gel coats, fiberglass, carbon fiber composites, and metals. At our core, we view sealers and primers not just as obligatory steps but as opportunities to be the most reliable and trouble-free aspect of the entire manufacturing process. Our goal is to contribute to smooth production runs, ensuring your orders are fulfilled consistently and supporting a positively moving bottom line.

Our Product - Chemlease®

Chemlease® sets the standard in composites molding with advanced mold primers that optimize process efficiency and enhance part quality by refining mold surfaces. Simultaneously, Chemlease® mold sealers offer targeted protection, specifically designed to safeguard investments in composites molds and tooling from chemical and physical damage during the molding process.

Common Problems Solved with This Solution

Common problems like rub marks and streaking can be effectively addressed with Chem-Trend’s advanced solutions. Rub marks, often caused by excess abrasion, can be minimized by ensuring proper tool preparation and regular touch-ups of the release agent.
When it comes to streaking during the process, The key lies in proper mold cleaning, followed by the application of release in a light, even coating using clean 100% cotton cloths.
