Price Increase for CoREZYN® and Silmar® Brand Products



(St. Paul, MN – May 14th, 2021) Interplastic Corporation announced today that it will raise the price of both Silmar and CoREZYN brand polyester resins, gel coats, bonding compounds and colorants up to $0.10 per pound. CoREZYN brand vinyl ester resins and gel coats will increase up to $0.30 per pound. This increase will take effect for all shipments on or after June 5th, 2021.

Basic raw materials continue to increase due to shortages and limited supply in all areas. Styrene, epoxy, isophthalic acid, fumed silica and others have further escalated. Availability is tight from all suppliers as demand remains high. Freight and packaging costs are also increasing on a regular basis. Interplastic will continue to work with suppliers to make sure we are able to maintain a consistent supply of products.
