Rosin modified maleic anhydride resin is a slight yellow transparent solid, which is adducts of gum rosin and maleic anhydride through the esterification by glycerol or pentaerythritol.
Applications for C5 petroleum resin include printing inks, paper sizing agents, and asphalt modifiers. It also serves as a binder in the production of composite materials such as fiberglass and carbon fiber composites.
Hydrogenated petroleum resin is a product that converts unsaturated hydrocarbons in petroleum resin into saturated hydrocarbons by hydrogenation of petroleum resin, and improves the hue, smell and weather resistance of petroleum resin. Mainly divided into C5 hydrogenated resin and C9 hydrogenated resin.,DCPD Hydrogenated Resin and Hydrogenated C5&C9
Hydrogenated dicyclopentadiene resins affect adhesive performance when used as tackifiers in styrene-block-copolymer-based hot-melt pressure-sensitive adhesives.
The styrene modified C5 resin HC5090 is hydrocarbon resin is a low molecular weight, aliphatic hydrocarbon resin, derived mainly from dienes and other reactive monomers. It is characterized by its light color, excellent balance of tack and of adhesive and cohesive properties, heat resistance, and wide compatibility.
TPR-560 is a high softening point modified terpene phenolic resin, which is characterized by high and low temperature resistance. TPR-560 has super cohesive force and excellent viscosity retention on adhesive, and is commonly used in pressure sensitive adhesive and hot melt adhesive.
Aromatic resins (C9 resins) are made from C9 hydrocarbon aromatics. Their composition depends on the hydrocarbon raw material (coal tar, crude oil). The softening points of these resins range over a wide range. Compared to C5 resins, they have a higher melt viscosity, are darker in color (dark yellow to brown) and have a higher softening point ranging from about 100 to 150°C. C9 resins are versatile resins that are compatible with many polymers.
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.
