Before the invention of semi-permanent release agents, wax and PVA were the common mold release for fiberglass molding which were very labor intensive and unable to produce multiple releases between applications. The transition to semi-permanent releases did provide significant labor savings and better mold throughput. However, there are issues that manufacturers may experience, such as pre-release, causing fish-eyes in gel coats, or poor release due to misapplication. This webinar addresses solutions to these issues.

Primary Topics:

  • Solutions to correct pre-release of parts from their molds
  • Recommendations on how to get the best gloss on molds and parts
  • Discussion of the use of release agents that have varying slip
  • New labor-saving products
