Process: Vacuum Infusion

In this process, the mold is filled with reinforcement, sealed, and then evacuated by vacuum pressure, thereby drawing the resin through the mold until the reinforcement is saturated. This process allows you to get a very high glass content, 65 - 70% by weight, resulting in a very strong but lightweight composite.

Typical products for this application are orthophthalic, COR45-BA-041, corrosion resistant isophthalic COR45-DZ-551, fast curing, COR45-BA-637, corrosion resistant vinyl ester, VE8100-50 (non-promoted), VE8101-50 (promoted) and VEX169-826. The VEX169-826 is approved by Det Norske Veritas (DNV) for “Certification and Classification of Boat 1997, Grade 2” and “Classification of High Speed and Light Craft, Grade 2”. 

We also formulate modified vinyl ester resins such as our VEX169-540 that have comparable physical properties to vinyl esters but are more cost effective.
