Composite Sheets



This orthophthalic-based resin is highly suitable for producing sheets using the hand lay-up method. It exhibits excellent fiber wetting properties and allows for easy separation from the mold, resulting in increased speed and quality of sheet production. The resulting final product is soft and free from any surface irregularities.

High Softness

Easy Molding

Excellent Wetting

No Scurf

High Transparency

This tractor may present a compact design but it’s customizable from top to bottom to meet a range of needs and execute projects of varying intensity. The robust 4-cycle diesel engine meets Tier-4 emission standards, while the Hydro-Max HST with auto throttle or Synchro-Shuttle transmission ensures a smooth ride. In the operator’s platform, the suspension seat and factory-installed joystick controls are designed for ultimate comfort and usability. The tractor’s high ground clearance makes operating on rocky or uneven terrain easier, and optional LED work lights and a high-capacity front-end loader allow you to customize the tractor for the job.

Frequently Asked Questions About Resins

Storage conditions

To ensure the utmost stability and preserve the optimal properties of resins, it is crucial to store them in sealed containers at temperatures below 24°C, away from sources of heat ignition and direct sunlight. For best results, it is recommended to warm the resin to a minimum of 18°C before usage. This pre-warming process guarantees proper curing and facilitates ease of handling throughout the application. By adhering to these guidelines, you can enhance the performance and longevity of the resin, ensuring successful outcomes in your projects.

As per customer requirements, the following features of Unsaturated Polyester Resins (UPRs) can be customized:
1. Gel time: The gel time of the resin can be adjusted based on specific needs. Gel time refers to the time taken for the resin to reach a semi-solid or gel-like state after the initiation of the curing process.
2. Curing time: The curing time, which is the duration required for the resin to fully harden and cure, can be modified to meet specific project timelines and requirements.
3. Thixotropic index: The thixotropic index of the resin can be tailored as per customer preferences. Thixotropy refers to the property of certain materials to become less viscous under applied stress and return to their original viscosity when the stress is removed.
4. Adding curing indicator: The option to include a curing indicator in the resin formulation is available. A curing indicator is a substance that changes color or exhibits a visual change to indicate the progress of the curing process. It is worth mentioning that this applies specifically to blue-colored resins, where the resin should change from blue to its natural color after curing. The blue color serves as an indicator for determining the complete curing time. If a blue-colored resin does not change to its natural color after curing, it has merely been pigmented with blue and does not possess a blue cure indicator.
5. Making resin pre-accelerated: The resin can be pre-accelerated during the manufacturing process. Pre-acceleration involves the addition of accelerators to the resin formulation before it reaches the customer, allowing for faster curing times upon application.
