Cashew Friction Particle

cnsl friction particle is used in disc pad brakes and drum linings as a stabilizing agent. These particles (sometimes called friction dust) have a resilient nature which cushions the engaging property of a piece of lining. Friction dust is crossed linked product obtained from the reaction of cashew nut shell liquid with different aldehyde donors like formaldehyde hexamine para formaldehyde to achieve the desired friction dust properties. Basically it is a phenol formaldehyde resin, which is polymerized and reacted with any one of the aldehyde donors and made to powder form of various standard mesh sizes.

Density(kg/m3) 40-45
Specific gravity 1.15

Cardanol is a naturally occurring Phenol in light pale yellow color manufactured from CNSL. It is a monohydroxyl Phenol having a long hydrocarbon Chain (C15H27) in the Meta position.
Cardanol also known as Cashew Phenol is obtained in the distillation process of technical CNSL under reduced pressure. The distillation takes place at high temperature and Distilled CNSL vapours are received through high vacuum. The average unsaturation of about two double bonds in the side chain of the Cardanol molecules make cross linking easy and provides a satisfactory gradual drying and baking properties to paints prepared from it. Because of its peculiar structure Cardanol Varnishes have high electric Insulation, greater resistance to water, chemicals and good flexibility.
Cardanol is a phenol which has a C15 unsaturated alkyl chain with 1-3 double bonds at meta position. The component of commercial Cardanol differs in the degree of unsaturation of the side chain but for the practical purposes it can be represented by the following formula.

C6H4(OH)-(CH2)7-CH=CH-CH2-CH=CH(CH2)2 -CH3

Properties : One of the significant advantages of the Cardanol is its amenability to chemical modification to effect desirable structural changes so as to get specific properties for making tailor-made polymers of high value. Thus, structural changes could be effected at the hydroxyl group, on the aromatic ring and on the side chain. The unique Molecular structure of Cardanol, especially unsaturation of long Hydrocarbon side chain, makes the cross linking easy on Polymerization. Also besides the side chain impacts hydrophobic nature to the polymer, its coating is Water and Weather resistant.

Applications

Cardanol is used as a primary building block for epoxy curing agents and epoxy diluents and modifiers. This natural alkylphenolic material has an aromatic ring that provides a strong chemical resistant backbone while the hydroxyl group gives strong adhesion and good reactivity for fast and low temperature cure. A long aliphatic side chain provides excellent water resistance, good flexibility, low viscosity, extended pot life, and excellent corrosion protection.
Cardanol has an excellent properties ideal for the coating industry. It is widely used to manufacture Epoxy Curing Agents and other resins for Paints, Varnishes, and Laminates. It's widely used in Rubber, Pesticides, Adhesives, Mineral Oils, Break Linings, Electrical isolation putty, ink printing.

Applications

Applications	Characteristics
Surface Coatings & Paints Marine Coating (Phenalkamines)	The Cardanol based resins have good compatibility with other synthetic resins such as alkyds, epoxies chlorinated rubber, phenolic etc., and can serve as raw material for variety of paints. The Cardanol based resins have an excellent anti-corrosive characteristics
Rubber	Pure Cardanol acts as a de-oxidant and plasticizer when incorporated into rubber
Bonding	Cardanol can be substituted for phenol by up to 30% in phenolic resins used as plywood binding resins and for the lamination industries for cost savings purposes.
Cardanol Based Resins: Novolac & Resol resins Oil & Alcohol soluble resins Phenol-Cardanol-Formaldehyde resin	Cardanol based resins show outstanding resistance to softening action of mineral oils and high resistance to acids & alkalis, it has antimicrobial and insect resistance properties. Cardanol based resins have found extensive uses in automotive brake lining applications as binders/friction dust
Cardanol Derivatives: Surface Active Agent Azo Dyes Wax Substitutes Mineral Oil Additives Pesticide Diluents and modifiers	Cardanol Derivatives have been used as antioxidants, stabilizers and demulsifiers for petroleum products as well as plasticizers and processing aids for rubber compounds and modifiers for plastic materials. Cardanol and it Derivatives are also used as modifiers in coatings, adhesives, sealants, rubber, plastic, elastomers , composites and inks, in cosmetics for skin , in mosquito abatement, to coat granules used for fertilizers, insecticides, plant protection agents, fungicides and drying agents.
Brake Lining & Clutch Facings	Cardanol based resins have found extensive uses in automotive brake lining applications as binders/friction dust improving impact properties and reducing fade considerably by dissipating heat faster than phenol-formaldehyde (PF) resins.

Cashew Nut Shell Liquid Resin

Material Nut Shell
Application Hair Oil
Color Light Cream
Purity 90%
Country of Origin Cameroon
Packaging Type Tinned Can
Form Liquid

It mainly consists of two naturally produced Phenolic Compounds i.e. Anacardic Acid and Cardol. Both of them are non-drying and cannot be dried up unless by chemical reaction.
CNSL Resin is a transparent viscous resin with golden color film. It is highly suitable for the surface coating application, where outstanding film properties and very high resistance to water and chemicals are required.
Therefore, CNSL Resin is used commonly as a paint raw material due to its high water and chemical resistant property.

Properties

CNSL Resin is the best modified Phenolic type. It offers the necessary traits of a straight phenolic nature without the oil bleeding and hence functions as a good binding agent.
The flexibility, thermal stability and impact resistance it provides, causes the decrease in the co-efficient of friction. It also combines the features of thermosetting and binding, especially used for Brake Lining.

Applications

Applications	Characteristics
Brake Lining	CNSL Formaldehyde (NOVOLAC) resins are used for brake liner binding preparation
Paint and coatings	Dark color enamels application Provide required gloss, flexibility as well as good mechanical strength, quick drying ability, Excellent resistance to water, acid, alkali Weather proof, heat and fire resistant An excellent anti corrosive protection Superior properties than those of conventional oils or synthetic resins The coating withstand alkalinity normally encountered with cathodically protected steel hulls
Primers for wood and metal	Red oxide metal primer, Zinc chromate primer, other primers Provides Resistance against water, acid, alkali and other chemicals Protects against Corrosion Improves gloss, increases flexibility and as well as hardness
Lacquer	Provides toughness and elasticity to the lacquer film To achieve an excellent gloss and superfine adhesive qualities Superior to those of ordinary oil paints in respect to resistance to oils, grease moisture and chemicals
Insulation Varnishes	To achieve excellent flexibility and resistance to other chemicals High gloss and adhesion properties High water repelling and low dielectric properties
Laminating industry Resins	Improves age hardening and better bonding to the substrate
Foundry core binders	Improves collapsibility of the core and enhances bench life and anti-damp behavior in comparison to conventional core binders
Friction resistant material	An excellent heat resistant material and as a partial substitute for phenolic resin to reduce cost
Rubber	Enhances the resistance of the product to aging, chemical attack and the action of solvents and acids
Polymer based cements	For good adhesion and resistance to moisture, acids and alkalis
