Family of polymersA family of polymers having a high glass transition temperature (40 – 50 °C), which may be used to form aqueous polymer solutions. The polymer solutions may be applied like a paint to form a transparent and glossy coating film on various surfaces, without the need of a coalescent - that is, the polymer solution is completely free of volatile organic compounds (VOC). Furthermore, good coatings may be obtained at relatively low temperatures (down to 5 °C).
Two grades of this polymer family and their dry coating properties are described:
Grade 1 of the Polymer family gives coatings which have:
- Excellent dry adhesion on both untreated metal and glass surfaces
- Excellent water resistance, retaining their adhesion on the aforementioned substrates even when fully immersed in water for a period of more than a week
This polymer could be used for example as a coating in the painting industry,...
Grade 2 of the Polymer family - gives coatings that have a selective solubility:
- They are resistant to water and alkali solutions
- They may be easily and efficiently removed using a weak acid.
- The film dissolution may be controlled in a precise and net manner, resulting in a net etching of the film.
This polymer could be used for example for: temporary coating or adhesive, home and personal care products...
