Paint stripping chemicals are solvents or solutions designed to remove old paint, varnish, or coatings from surfaces. Coating systems involve applying protective or decorative layers, such as primers, paints, or sealants, to substrates. Both are used in industrial, automotive, and construction applications for surface preparation and finishing.

Paint Stripping Chemicals:
- Size: Typically available in 1-gallon to 55-gallon containers
- Grade: Industrial or commercial grade
- Viscosity: Low to medium (500-2,000 cP)
- Buoyancy: Not applicable (non-floating)
- Material: Solvent-based (e.g., methylene chloride, NMP) or bio-based (e.g., soy, citrus)

Coating Systems:
- Size: Varies (quarts to 5-gallon pails for liquids; powder coatings in 20-50 lb bags)
- Grade: Epoxy, polyurethane, acrylic, or alkyd-based
- Viscosity: Medium to high (1,000-10,000 cP for liquids)
- Buoyancy: Not applicable (non-floating)
- Material: Liquid or powder coatings (resins, pigments, additives)
