- the synthetic resin used as a binder can be used in the form of an emulsion, dispersion or solution. Bitumen or bituminous substances up to 10% by weight can also be used as binders. In addition, known dyes, pigments, water-repellents, odor correctors and
- Inhibitors or anticorrosive agents and the like are used.
- At least one alkyd resin or modified alkyd resin and / or a drying vegetable oil is preferably contained in the agent or in the concentrate as the organic chemical binder.
- Alkyd resins with an oil content of more than 45% by weight, preferably 50 to 68% by weight, are used.
- binder mentioned can be replaced by a fixative (mixture) or a plasticizer (mixture).
- fixative mixture
- plasticizer mixture
- additives are intended to volatilize the active ingredients and crystallize or precipitate! prevent. They preferably replace 0.01 to 30% of the binder (based on 100% of the binder used).
- the plasticizers come from the chemical classes of phthalic acid esters such as
- phosphoric acid esters such as tributyl phosphate phate
- adipic acid esters such as di- (2-ethylhexyl) adipate
