Crosslink PVA Physically is a type of polyvinyl alcohol (PVA) that is crosslinked or bonded together using physical means, such as UV light or a sensitizer, rather than through a chemical reaction.
The purpose of crosslinking PVA physically is to increase its strength and durability, as well as improve its resistance to solvents and heat. This makes it a more versatile and useful material in various applications.
Crosslinking PVA physically involves using external stimuli, such as UV light or a sensitizer, to bond the PVA molecules together. In contrast, chemically crosslinking involves a chemical reaction between the PVA molecules to form stronger bonds.
Using UV light for crosslinking PVA physically offers several benefits, including faster reaction times, better control over the crosslinking process, and reduced environmental impact since no additional chemicals are needed.
UV light and sensitizers can be used to crosslink various materials, including PVA, polyurethane, and acrylics. However, the specific materials and conditions required for successful crosslinking may vary.
