Modified tackifying resin is yellow to brown flake or granule,modifying agent and parasubsititeted alkylphenols.
1:Modified tackifying resin has the characteristics of long-term effective,nice moisture stability and high viscosity-promoting ability.
2:Modified tackifying resin can be widely used inNR,SBR,BR,EPD, or blended rubber,for manufacturing hifhperformace tires,vonvey belst,v-belts,hoses,rollers,rubber plates,linings,wire and cable,adhesive,retreading materials and so on.
3:Modified tackifying resin can endow rubber compound not only with excellent initial adhesiveness,but also with good adhesivenese in storage or in hot and humid condition.It may act as softener and plasticizer during the processing,and has no effect on the curing behavior and the physical properties.Its viscosity-promoting ability superior to para-tert-butylphenol(or para-tert-octylphenol),formaldehyde resin.
4:Modified tackifying resin should be added under the temperature higher than its' softening point in the early period of mixing,to ensure the resin's homodisperse and to get the best viscosity-promoting effectiveness.It can save the use level of processing oil to a certain degree.The recommended dosage is 2-5phr.
Kept in dry and ventilating place,protected from heat and fire,the storage life is one year.The products that exceed storage and qualified can be used.
Packed in knitted bags lined with a layer of kcraft paper bag and a layer of plastic bag.The netweight is 25kg per bag.
