Both PVA (Polyvinyl Acetate) and PVAc-based emulsion adhesives are primarily used for what purpose?
Correct answer: C. As adhesive materials
- A. As textile fibers
- B. As coating materials
- C. As adhesive materials
- D. As packing materials
Explanation
PVA (Polyvinyl Acetate) and PVAc-based emulsion adhesives are primarily used as adhesive materials because they effectively bond a variety of surfaces. They are widely used in woodworking, paper, and packaging industries. The other options are incorrect because PVA and PVAc are not primarily utilized as textile fibers, coating materials, or packing materials. These applications require different material properties that PVA and PVAc do not possess.

About Industrial Chemistry
Industrial chemistry applies chemical reactions and material properties to the manufacture of adhesives, dyes and polymers. Coverage includes addition and condensation polymerisation, thermoplastics and thermosetting polymers, the structural basis of colour in dyes, and how adhesive composition enables bonding between surfaces.
