Part 3: Application
1. PGDA can dilute isocyanate curing agent of water-based 2KPU coating. PGDA is a hydroxyl-free aprotic solvent, which has obvious viscosity reduction effect on isocyanate curing agent; it has a certain hydrophilicity and is compatible with the paint. Appropriate volatilization speed assists the paint resin to form a film, which is conducive to the emulsification of the curing agent in water and the closer contact with the emulsion particles. PGDA is more conducive to the operability time of the coating, the non-foaming film thickness, the gloss of the paint film, the establishment of hardness, etc., lower odor, safety and environmental protection.
2. Synthesis of resins such as hydroxypropyl dispersions.
3. Coalescent: Using PGDA together with DB is very cost-effective, and using PGDA together with DBA in water-based plastic paint has high film-forming efficiency, good compatibility and excellent paint film.
4. Automotive paint, high-end deodorant wood coatings (non-toxic deodorant, high solubility, compatible with two-component polyurethane system, high gloss of paint film).
5. High-end deodorant solvent in inkjet, screen printing ink, ink and other fields.
6. Organic synthesis intermediates, cleaning, brighteners, plasticizers, printing and dyeing finishing agents, adhesives and other industrial applications.
