Properties / Applications

CR-5

Generally speaking, R5 has good compatibility

with many solvents, plasticizers and binders.

However, it is necessary to test the solubility /

compatibility in each case.

R5 can be used to formulate fast-drying anticorrosion coatings with

good weather stability and resistance

to water and chemicals. Used as a

combination binder, for e.g. alkyd resins,

acrylates and ketone resins. R5 improves

the initial adhesion and water repellency

of the system.

CR-10

Generally speaking, R10 has good compatibility

with many solvents, plasticizers and binders.

However, it is necessary to test the solubility /

compatibility in each case.

R10 can be used to formulate fast-drying anticorrosion coatings with

good weather stability and resistance

to water and chemicals.

CR-20

Generally speaking, R20 has good compatibility

with many solvents, plasticizers and binders.

However, it is necessary to test the solubility /

compatibility in each case.

R20 can be used to formulate fast-drying anticorrosion coatings with

good weather stability and resistance

to water and chemicals. It can also be

used in abrasionresistant concrete floor

coatings and roadmarking paints.

CR-40

Generally speaking, R40 has good compatibility

with many solvents, plasticizers and binders.

However, it is necessary to test the solubility /

compatibility in each case.

R40 can be used to formulate fast-drying anticorrosion coatings with

good weather stability and resistance

to water and chemicals. Used as a

combination binder for e.g. alkyd resins,

acrylates and ketone resins, R40 improves

drying properties and resistance to inorganic

acids.

CR-90

Generally speaking, R90 has good compatibility

with many solvents, plasticizers and binders.

However, it is necessary to test the solubility /

compatibility in each case.

R90 can be used to formulate fast-drying swimming pool and concrete

coatings with good weather stability

and resistance to water and chemicals.

CR-130

R130 is soluble in aromatic and chlorinated

hydrocarbons and in ethyl acetate.

On account of its high polarity, R130 is

especially suitable for the formulation

of primers and key coats for rubber/metal

bonds. Binder for, among other things, adhesives.

CR-170

R170 is soluble in aromatic and chlorinated

hydrocarbons and in ethyl acetate.

On account of its high polarity, R170 is

especially suitable for the formulation of

primers and key coats for rubber/metal

bonds. Binder for, among other things, adhesives.
