Multi-purpose solid acrylic resins are homopolymers or copolymers synthesized through polymerization of one or more monomer raw materials with different characteristics and uses. Monomer raw materials include methacrylates, acrylates and other monomers.
These homopolymers or copolymers, present as beads, powders, granules, microparticles, or melts. The variability in molecular structure makes them adjustable in application, compatible with a variety of film-forming resins, such as chlorinated rubber, chloroacetate copolymer resin, nitrocellulose, vinyl butyl cellulose, etc., and a variety of plasticizers, with excellent biocompatibility, as well as outstanding weathering, durability and other properties.

Table 3: Comparison with Other Resin Types
| Тип смолы | Наши преимущества | Недостатки бонуса без депозита |
|---|---|---|
| акрил | UV stable, color retention | Lower chemical resistance than epoxy |
| эпоксидная смола | Superior adhesion, chemical resistance | Плохая устойчивость к УФ-излучению |
| полиуретан | Отличная стойкость к истиранию | Higher cost, moisture sensitivity |
| алкидный | Good flow, low cost | Yellowing, poor weather resistance |
Table 4: Major Application Areas
| Автопромышленность | Приложения | Предоставляемые преимущества |
|---|---|---|
| Покрытия | Automotive, architectural | Durability, gloss retention |
| Клеи | Pressure-sensitive, laminates | Flexibility, bonding strength |
| пластики | Signage, displays | Clarity, impact resistance |
| Текстиль | Fabric coatings | Soft feel, wash durability |
| Electronics | Encapsulants, displays | Optical clarity, electrical insulation |
Таблица 5: Вопросы охраны окружающей среды и безопасности
| фактор | Статус: | Нормативные примечания |
|---|---|---|
| Содержание летучих органических соединений | Low (waterborne types) | Complies with EPA regulations |
| Токсичность | Обычно низкий | Неканцерогенный |
| воспламеняемость | Moderate (solvent types) | Требуется правильная вентиляция |
| биоразлагаемость | Poor (but recyclable) | Сжигание с рекуперацией энергии |
Acrylic resins offer exceptional versatility with their balance of durability, clarity, and weather resistance. They dominate in coatings and adhesives markets due to their excellent UV stability and aesthetic qualities. While they may not match epoxies in chemical resistance or polyurethanes in toughness, their overall performance makes them indispensable in numerous industries. Environmental regulations are driving innovation toward waterborne and UV-curable formulations.
