Dear Sir
Following are the some application of CNSL.
CNSL based surface coatings possess excellent gloss and surface finish with optimum levels of toughness and elasticity. It is widely known that CNSL resin is added to synthetics by paint/varnish manufacturers to control properties and to reduce cost. Its anti-microbial, acid resistant and rust proof properties are well known and have been utilized in protecting a bottom of the boat hulls. Because of its dark color, its outlets are restricted to anti corrosion primers, black enamels, marine paints.
CNSL is an excellent raw material for the number of anti-corrosive paint formulations
CNSL modified by heating in the presence of certain accelerators give stoving enamels resistant to alkali and acid solutions, mineral and fatty oils and various organic solvents.
Coating compositions possessing insecticidal properties are obtained by adding DDT, gammexane, etc. to CNSL or chlorinated CNSL, after treatment with formaldehyde, gums and resins and drying or semi-drying oils
CNSL is also used as a substitute for linseed oil in the manufacture of foundry core oil, which is used as a binder in the foundry.
Used as a processing aid, which enhances the vulcanization properties. CNSL enhances the insolubility of natural rubber vulcanizates in petroleum solvents.
CNSL used to provide oxidative resistance to sulfur-cured natural rubber products.
Sulfurated CNSL is added to rubber gum stock or nitrile rubber to improve the processability, mechanical properties and resistance to crack and cut
Adhesives suitable for plywood are made
by oxidizing CNSL with potassium permanganate or manganese dioxide at 100degC reacted with para-formaldehyde and compounded with CuCl2.
Also CNSL modified with furfural, aniline, xylol, etc. gives good plywood adhesives.
It is highly suitable for 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
These resins can be used for Surface Coatings with or without oil modification when high chemical resistance is desired
Excellent material for the purposes like Insulating Varnishes, Molding Powders, Brake Lining Compositions, etc.
Resole type CNSL formaldehyde resin is used as adhesive in the preparation of composite wood, medium density particle board etc.
Proven material in the formation of foundry cores
Incorporation of CNSL products in rubber improves tensile strength and abrasion resistance, reduces fatigue, enhances self adhesion, rubber to cord adhesion, contributes to antioxidant and antiozonant activity. The fast curing cashew modified phenol-formaldehyde resins enhance the resistance of the product to aging, chemical attack and the action of solvents and acids.
with above mentioned application we can definitely use CNSL in manufacturing of composite.
you can go through this article you can get some idea for composite preparation.

How it cure...The paper provided doesn't have any information about the curing of CNSL Resin.
Ok you want curing of CNSL Resin
You can go through below mention paper
