Petrolium Resin C9 HT9140 Hydrocarbon Resin for Paints

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.

Crosile®75 (Bis(3-triethoxysilylpropyl)disulfide) TESPD is a bifunction polysulfidic organosilane and has been widely in the rubber industry. Crosile®75 TESPD is used to improve the reinforcing capability of fillers with silanol group on the their surface,and also as an integral part of curing systems to improve cross-linking network properties. Compared to the Crosile®69 (Bis(3-triethoxysilylpropyl)tetrasulfide), Crosile®75 has a higher temperature stability and therefore allows higher mixing temperatures. Crosile®75 imparts greater tensile strength, higher module, reduced compression set, increased abrasion. resistance and optimized dynamic properties.
