Dry Bonding agents are used as a direct bonding system which leads to high adhesion value between Rubber and Fabric (dipped or undipped) / coated steel cords for the manufacture of range of products viz. Tyres, Belts (Transmission, Conveyor), Hoses, Moulded items, Rubberised Fabric, etc.
Dry Bonding system consists of three components viz., resorcinol donor, methylene donor and ppt. silica and needs to be added in the rubber compound during the mixing of the rubber compounds. The adhesive resin, which is formed by the in-situ reaction of resorcinol & methylene compound at the time of vulcanisation, are migrated to the interface of fabric/steel cords and forms a stable chemical bridge between reinforcing materials/substrates and the rubber compound.

2.BIO-BASED PLASTICISER
This is used to improve the dispersion of the powdered materials in the rubber matrix during the mixing stage of the Rubber Compounds and can shorten the mixing time by faster filler incorporation, without significantly influence on the physical properties of the Rubber compound. Available in various grades, zinc based, zinc-free based as well.
Helps in peptizing the Natural Rubber and Synthetic Polyisoprene rubber thereby the processability of the compound noticeably improved without lowering the molecular weight of the Rubber.
Improves the homogeneity of blend of polymers/Rubbers with different polarities and viscosities and also improves the rate of incorporation & dispersion of the compounding ingredients, which improves the processing performance and batch-to-batch uniformity of the rubber compounds.
In addition to the performances of dispersing activity, it also aids in release the rubber compounds from the mill sticking and mould sticking, thereby reducing the mould fouling.
Process Oils for Rubber are classified based on their properties as,
1.AROMATIC
2.NAPTHENIC
3.PARAFFINIC & HIGH VISCOSITY, HIGH FLASH POINT GRADES
4.WHITE OIL
Aromatic Process Oils.: High solvency oils produced through blending of judiciously selected feed stocks extracted by the use of a controlled liquid extraction process from paraffinic lubricant fractions. These oils contain a large number of aromatic ring carbons and therefore exhibit low volatility and high viscosity.
Naphthenic Type Process Oils: Light coloured, highly refined oils produced by blending of judiciously selected base stocks which ensures that the oils have higher Naphthenic ring carbon content. These oils exhibit excellent compatibility, good colour stability and non-staining properties.
Paraffinic Process Oils: – Highly refined Oils produced by blending of judiciously selected base stocks manufactured by the distillation, solvent extraction & dewaxing of select high paraffinic crude. They have low solvency and high aniline point with low aromaticity, excellent colour & thermal stability.
WHITE OILS: This can be used for high colour requirement compounds & also in the road marking paints, plastics compounds.
1. NATURAL RECLAIM
WHOLE TYRE RECLAIM
This is manufactured from the used Tyres and can be used for moulded, extruded products. The grades are SUPERFINE, FINE, MEDIUM, COARSE depends on the grain size of the reclaim rubber.
LATEX BASED
From the NR latex based products like, Gloves(Examination/surgical), Rubber bands, Elasic threads, sheets etc.
This is manufactured from the used EPDM based profiles and other products and these grades are specially double refined to suit all the processing needs of the EPDM compounds.
C.I.RESINS
Synthetic C.I. Resin D.G. TACK 80
THIS IS LOW SOFTENING POINT C.I. RESIN.
Because of the presence of the double bond in the side chain -> possessed by the Allyl group, makes C.I. resin responsible for having free double bond in polymeric chain structure, thereby gives excellent Green Tack to the Rubber compounds. This double bond is also get cured in the vulcanisation process.
HYDROCARBON RESINS:
These resins are manufactured from petroleum derivates and having the series of C5 based aliphatic resins, C9 based aromatic resins, and C5/C9 modified hydrocarbon resins
TACKIFYING RESINS
Creating tack in a rubber compound is a surface phenomenon that relies on contact between the surfaces and formation of chemical bonds
Addition of all resin tackifiers to rubber compounds improves the ability of the surfaces to make contact Addition of phenolic resins to rubber compounds allows the formation of chemical bonds based on intermolecular forces of attraction. Phenolic tackifier resins are most able to form this type of chemical bonds. Better tack means product can be used at lower levels – typically added at around 3-5 pphr – optimum level, usually determined empirically
Lower levels of tackifier in formulation results in rubber compounds with reduced heat build up
CURING RESINS
Intended to crosslink unsaturated elastomers
Contains methylol or bromo-methyl groups for reactivity
Require halogen donor for activation
Acts as plasticizer until cure temperatures are reached.
Brominated varieties are available for rapid cure and do not require halogen donor.
HEXAMINE MODIFIED REINFORCING RESINS
A Reinforcing resin, which are added to rubber compounds to adjust physical properties of the compound after it has been fully cured,To provide the rubber compound increased Hardness, toughness, stiffness, abrasion resistance, tear resistance

1. MOULD RELEASE AGENT
Mould release agent helps to aid the release of the moulded rubber products from the mould.
2. INSIDE TYRE PAINT
This is applied into the inner side of the un-cured tyre to have very good slip of the bladder into the green tyre.
3. OUTSIDE TYRE PAINT
This is the water based dispersion specially designed to have high rubber to rubber adhesion and the combination of fillers/binder aid rubber flow to reduce the splice cracking and to be sprayed onto the outer surface of the un-cured tyre
4.FINISH PAINT
This helps is rectifying the moulded minor defects, on the surface of the finished rubber products.
5. DRC – DEVULCANISED RUBBER COMPOUND
“De-vulcanise” as the name refers to the process in which the cross-linked bonds in the rubber product cleave (de-crosslink) either totally or partially and can be re-vulcanised & utlilised again like the virgin rubber.
DRC – De-vulcanised Rubber compound mainly refers to the de-linking of the sulphur linkages of the cured Rubber Products through the mechano-chemical process, from the commonly used rubber products such as tyres, extruded, moulded & calendered product.
SI-69, PEG 4000 – used as coupling agents for precipitated silica fillers used in the rubber compounds.
This is used for absorbing the moisture in the rubber compounds and is very helpful in eliminating the porosity in the rubber products produced in all the rubber process methods, including moulding, extrusion, calendered processes…
