Notes

(1)	In this subclass, the following terms or expressions are used with the meanings indicated:

-	"use of materials for coating compositions" means the use of known or new polymers or products;

-	"rubber" includes:

(a)	natural or conjugated diene rubbers;

(b)	rubber in general (for a specific rubber, other than a natural rubber or a conjugated diene rubber, see the group provided for coating compositions based on such macromolecular compounds);

-	"based on" is defined by means of Note (3), below;

-	"filling pastes" means materials used to fill up the holes or cavities of a substrate in order to smooth its surface prior to coating. [5]

(2)	In this subclass, coating compositions, containing specific organic macromolecular substances are classified only according to the macromolecular substance, non-macromolecular substances not being taken into account.

Example: a coating composition containing polyethene and amino-propyltrimethoxysilane is classified in group C 09 D 123/06.

However, coating compositions containing combinations of organic non-macromolecular compounds having at least one polymerisable carbon-to-carbon unsaturated bond with prepolymers or polymers other than unsaturated polymers of groups C 09 D 159/00 to C 09 D 187/00 are classified according to the unsaturated non-macromolecular component in group C 09 D 4/00.

Example: a coating composition containing polyethene and styrene monomer is classified in group C 09 D 4/00.

Aspects relating to the physical nature of the coating compositions or to the effects produced, as defined in group C 09 D 5/00, if clearly and explicitely stated, are also classified in this subclass.

Coating compositions characterised by other features, e.g. additives, are classified in group C 09 D 7/00, unless the macromolecular constituent is specified. [5]

(3)

In this subclass, coating compositions comprising two or more macromolecular constituents are classified according to the macromolecular constituent or constituents present in the highest proportion, i.e. the constituent on which the composition is based. If the composition is based on two or more constituents, present in equal proportions, the composition is classified according to each of these constituents.

Example: a coating composition containing 80 parts of polyethene and 20 parts of polyvinylchloride is classified in group C 09 D 123/06. A coating composition containing 40 parts of polyethene and 40 parts of polyvinylchloride is classified in groups C 09 D 123/06 and C 09 D 127/06. [5]

(4)

In groups C 09 D 101/00 to C 09 D 201/00, it is desirable to add the indexing codes relating to additional macromolecular constituents of the coating composition. The indexing codes, which are chosen from the said groups, have the same numbers as the classification symbols, but a colon is used instead of the oblique stroke, and should be linked.

Example: a coating composition containing 80 parts of polyethene and 20 parts of polyvinylchloride is classified and indexed as follows: C 09 D 123/06 // (C 09 D 123/06, C 09 D 127:06) [5]

(5)

Attention is drawn to Chapter IV of the Guide which sets forth the rules concerning the application and presentation of the different types of indexing code. [6]
