Liquid plastic is a high-performance solution developed from polyurethane (PU) systems, designed to simulate the rigidity of conventional plastics such as polypropylene and polyethylene, but with significant advantages. Unlike traditional polymers, liquid plastic does not expand and, once cured, presents a solid, tough surface similar to thermosetting plastics, meaning it does not melt under heat. This material is ideal for a variety of industrial and prototyping applications, thanks to its unique combination of strength, fast cure and versatility.
The composition of Liquid Plastic
Liquid plastic is formulated from a combination of polyol and isocyanate, with the addition of specific catalysts and additives that ensure optimized resistance, adhesion and curing speed properties. In Amino products, part of the composition of our products comes from renewable sources, such as vegetable oils, which makes them a more sustainable choice compared to conventional materials derived exclusively from petroleum.
Main Features:
- Fast curing: Liquid plastic can reach its final form in minutes, ideal for production and repair processes that require agility.
- High strength: Its rigidity after curing provides a durable surface, even under adverse conditions such as extremely low temperatures.
- Sustainability (in Amino products): In specific versions, such as those from Amino, part of their composition comes from renewable sources, aligning with practices to reduce environmental impact.
- Application Versatility: Can replace toxic and difficult-to-handle materials, such as polyester, providing safety and efficiency.
Why choose Liquid Plastic?
Liquid plastics are different from other materials due to their specific structure and properties, which allow for a wide range of applications and solutions to complex problems. Unlike polyester resins, liquid plastics do not emit toxic odors, making it easier to work indoors and promoting a safe working environment. In addition, the curing speed reduces the waiting time between application steps, enabling faster and more cost-effective production.
Benefits of Liquid Plastic Over Polyester and Other Materials
- Reduced Toxicity: The absence of toxic odors makes liquid plastic much safer for operators and also for environments close to the workplace.
- Production Efficiency: With a curing time of just a few minutes, it facilitates rapid production processes, making it ideal for prototyping and rapid repairs.
- Sustainability: In Amino products, the presence of raw materials from renewable sources reinforces its environmentally responsible profile, making it a sustainable alternative.
- Versatility in Application: Can be used for repairs at very low temperatures, molding of technical parts and replacement of conventional materials in various industries.
Applications of Liquid Plastic
Liquid plastic was initially designed to replace DCPD, a material widely used in truck bumpers. However, its use has rapidly expanded, finding a variety of applications including:
- Cold Room Repairs: The ability of liquid plastic to cure quickly, even at temperatures as low as -26°C, makes it an ideal solution for cold room repairs without the need for shutdown, avoiding energy loss and maintaining the integrity of the controlled environment.
- Rapid Prototyping and Technical Parts: Its fast curing and adjustable viscosity allow the production of detailed prototypes in a matter of minutes. This is especially useful for the manufacture of technical parts that require precision and high-quality finishing.
- Replacing Toxic Resins: Liquid plastic can replace polyester resins in applications involving fiberglass lamination, eliminating odors and toxic gases, which reduces the need for stringent personal protective equipment.
Liquid Plastic Amino Solutions
Amino offers a specialized line of liquid plastic products that have been developed to meet different industrial applications and demands. Each of them has been formulated to provide the best combination of viscosity, cure time and mechanical strength.
- Amipol PCT 2558: With an extremely low viscosity, Amipol PCT 2558 is the ideal choice for rapid prototyping and the production of detailed parts. Its fluidity allows it to copy the details of any mold with precision.
- Amipol PCT 2574: With superior mechanical strength and slightly higher viscosity, PCT 2574 is recommended for applications where additional flexibility and impact resistance are required, such as in the molding of more robust parts.
- Slow Cure System: This system is designed for applications that require a longer cure time, such as large surface laminations. It cures in about six minutes, allowing for adequate handling of larger and more complex projects.
These products are highly adaptable and can be adjusted according to the specific needs of each customer, offering customized solutions for the most varied industrial challenges.
Advantages of Liquid Plastic for Industry
Liquid plastic brings significant advantages to several industries, enabling faster, safer and more economical production. Its main advantages include:
- Durability and High Strength: After curing, the liquid plastic is impact and wear resistant, offering considerable durability for structural and finishing parts.
- Versatility in Different Environments: Its resistance to low temperatures allows its use in environments such as cold rooms, where conventional materials could fail.
- Efficiency and Reduced Downtime: With extremely fast curing, liquid plastic allows for immediate repairs and accelerated prototyping, minimizing interruptions to production processes.
- Sustainability: The presence of renewable sources in Amino products contributes to more sustainable industrial practices and reduces the consumption of petroleum derivatives.
