Abstract
Solutions of aminotriazine resins at least 30 mol % of whose alkylol groups are etherified with a C1-C16 alkanol in a mono-C1-C4 alkyl glycol of the formula R1—O—(R2—O—)w(R3—O—)x(R2—O—)y(R3—O—)z H. I where R1 is C1-C4 alkyl, R2 is CH2—CH2 and R3 is and w, x, y and z are an integer from 0 to 10 and at least one of them is other than 0 or in a solvent mixture which consists to the extent of at least 20% by weight a of mono-C1-C4 alkyl glycol of the above formula.
Claims5
A process for preparing an aqueous curable coating composition, which comprises adding a solution comprising a water-insoluble aminotriazine resin at least 30 mol % of whose alkylol groups are etherified with n-butanol in a mono-C1-C4 alkyl glycol of the formula
- R1—O—(R2—O—)w(R3—O—)x(R2—O—)y(R3—O—)zH I
- where R1 is C1-C4 alkyl, R2 is CH2—CH2 and R3 is
- and w, x, y and z are an integer from 0 to 10 and at least one of them is other than 0, or in a solvent mixture which comprises at least 50% by weight of a mono-C1-C4 alkyl glycol of the above formula,
- as a curing agent, to the aqueous coating composition.
