Water-based primers are coatings applied to materials before painting to ensure better adhesion of paint to the surface and increase paint durability). They are typically made up of synthetic resin, solvent, and additive agents). Here are some details about water-based primers from the search results:
Positive aspects:
- Water-based primers have a lower solvent content, which makes them less harmful to the environment and human health.
- They can reduce the absorption of moisture and solar radiation, which can improve resistance to the outside.
- Some water-based primers can be used on dirty surfaces that cannot be cleaned or before painting light colors over a dark finish).
Negative aspects:
- None of the search results provided negative aspects of water-based primers.
Ingredients or materials:
- The ingredients of a water-based primer can vary depending on the specific product. For example, one patent describes a water-based primer composition comprising an organic solvent selected from 2,5,7,10-teiraoxaundecane (TOU) .
- Another patent describes a primer composition that includes an aqueous dispersion of at least one thermosetting resin curable at an elevated temperature and at least one organosilane.
- A safety data sheet for a water-borne primer lists the following ingredients: Skin Sens. 1A, H317 Aquatic Acute 1, H400 (M=10) Aquatic Chronic 1, H410 (M=1) EUH071.
