Chlorinated rubber alkyd resin combinations

Composition. Chlorinated rubber combination paints contain a second resin as the property-determining binder. The chlorinated rubber is added to an alkyd resin, acrylic resin, or bituminous substances to improve properties such as drying rate, water resistance, or chemical resistance. This application only accounts for a small proportion of the total chlorinated rubber consumption. 

General paint coating systems are a combination of oil-type rust preventative primer and long oil alkyd resin paint or chlorinated rubber paint (intermediate and overcoats) with a total thickness of less than 150 p,m. These are applied in relatively mild atmospheres such as rural, mountain, and city. 

Chlorinated rubber is compatible with alkyds of similar linearity and low polarity. Most of the highway marking points in the United States are based on a combination of chlorinated rubber and a compatible alkyd resin based on soybean oil. 

Binders of paints are normally vegetable oils, e.g., - linseed, dehydrated - castor, - soybean, ->tung and - oiticica oils as such (-xlrying oils) or in modified form (->alkyd resins). They are often combined with numerous synthetic resins. Natural resins (- resins, natural) are also applied in special applications where their high price is acceptable. Decorative - casein paints for plaster walls have lost importance. Chlorinated and cyclized - rubber are also in use (swimming pool coatings).
