Rosin Modified Maleic Resin

Rosin modified maleic resin can be esterified by adding gum rosin to maleic anhydride, glycerol, or pentaerythritol. This type of resin is frequently used in the paint industry and is highly compatible with nitro-cotton, making it ideal for creating nitrocellulose lacquer. The finished product has a light color and retains its quality over time. Furthermore, this type of resin is suitable for use in ink and as a glossing agent for paper.
