SOLUBLE COATING COMPOSITIONS FOR TEMPORARY PROTECTION OF SURFACES |
摘要 |
<p>An aqueous composition which is suitable for producing a temporary protective-coating upon a surface which is prone to deterioration or damage, particularly a bare metal surface, comprises an aqueous medium and, dissolved or dispersed therein in salt form, an addition polymer having a specified molecular weight and glass transition temperature which incorporates residues of one or more hydrophilic monomers and carries carboxyl groups equivalent to a specified acid value. The coating can be removed when desired by treatment with dilute aqueous alkali.</p> |
