Hydrogenated resin No. 0

Technical analysis of hydrogenated resin No. 0

I. Main types and raw materials

Hydrogenated petroleum resin No. 0:

C5 hydrogenated resin: Made from cracked carbon five fractions, through cationic polymerization and hydrogenation process, with light color (iron cobalt color number <5#), softening point ≥95℃, suitable for hot melt adhesive, pressure sensitive adhesive and rubber product modification, can improve colloid aging resistance and compatibility.

C9 hydrogenated resin No. 0: Made by copolymerization and hydrogenation of carbon nine fractions and aldehydes, with molecular weight <2000, low brittleness and strong viscosity, suitable for paint, ink and paper additives, and excellent compatibility with elastomers such as SBS and SIS.

DCPD hydrogenated resin: Made by hydrogenation and refining of dicyclopentadiene, with colorless and transparent particles, softening point 90-145℃, outstanding weather resistance (UV aging resistance >1000 hours), dedicated to high-end adhesives, automotive interiors and medical and health products.

Hydrogenated Epoxy Resin No. 0: TaiLuck-ST3000: Developed by Tohto Kasei, Japan, it achieves yellowing resistance (ΔE＜2.0@UV aging) through hydrogenated bisphenol A epoxy resin. After anhydride curing, the glass transition temperature reaches 80℃, which is suitable for outdoor castings, wind turbine blades and LED packaging.

2. Core Performance Advantages

Optical and Weather Resistance: Hydrogenated petroleum resin No. 0 has stable chromaticity (YI≤2.2), transparency＞90%, excellent UV resistance, and is suitable for packaging materials and automotive coatings with high appearance requirements.

Hydrogenated epoxy resin has outstanding long-term aging resistance. The outdoor coating has no obvious yellowing after 10 years of use, and the anti-pollution performance is improved by 30%.

Mechanics and Compatibility: C5 hydrogenated resin has high viscosity enhancement efficiency (peel strength increased by 20-30%), good compatibility with plastics such as EVA and PO, and can reduce the processing temperature of hot melt adhesive by 10-15℃. DCPD hydrogenated resin has a temperature resistance of 150°C and a dynamic bonding strength of >3.5 MPa, which is suitable for high-speed tire rubber and engineering plastic modification.

Environmentally friendly adaptation:

The VOC content of hydrogenated resin is <50 ppm, and it has passed RoHS and PAHs certification, meeting the environmental protection standards of medical-grade adhesives and food contact materials.

3. Application scenarios and selection suggestions

Adhesive field:

Hot melt adhesive and pressure-sensitive adhesive: C5 hydrogenated resin (such as DR-5300) optimizes colloid fluidity and is suitable for bonding non-woven fabrics, labels and automotive interiors.

Medical-grade adhesive: DCPD fully hydrogenated resin (such as DR-5395) has a chromaticity YI <2.2, is non-toxic and odorless, and is specially used for surgical patches and disposable sanitary products.

Coatings and inks:

Outdoor protective paint: TaiLuck-ST3000 resin is used as the base material, and the acid and alkali resistance of the coating film is increased by 50%, which is suitable for heavy corrosion protection scenes such as bridges and ships.

High-transparency ink: C9 hydrogenated resin is compounded with polyurethane solvent, the ink is quick-drying, and the gloss of the printed product is ≥90 GU.

Plastic and rubber modification:

Engineering plastics: DCPD hydrogenated resin (DR-5340) is blended with PP/PE to increase the impact strength by 15-20%, suitable for car bumpers and home appliance shells.

Tire rubber: Hydrogenated C5 resin enhances the rubber-cord interface adhesion and extends the dynamic fatigue life by 30%.
