Resins

Castro Composites specializes in high-quality thermoset resins. We exclusively work with the best brands in the market to provide you with exceptional solutions in the field of composite materials.

Our focus is on quality and performance. If you're looking for a specific resin brand, it's important to highlight that we only work with those that meet the highest quality standards. Your satisfaction and the final results are our priority.

Thermoset resins play an essential role in creating durable and efficient structures. These resins undergo an exothermic reaction triggered by the combination of the resin with the hardener or catalyst. When combined with reinforcement fibers, these resins generate high-performance composite materials. They act as elements that keep the reinforcements cohesive and preserve the mold's geometry.

In addition to their bonding function, these resins distribute mechanical loads and establish thermal limits. Factors like Glass Transition Temperature (Tg) and Heat Deflection Temperature (HDT) influence the response to different temperatures.

We explore various resin variants that we market:

Epoxy Resin: Noted for its exceptional durability and adhesion. Ideal for high chemical and mechanical resistance, as well as stability at high temperatures.
Vinyl Ester Resin: Ideal for corrosive and marine environments due to its chemical resistance and durability.
Urethane-Acrylic Resin: Balances flexibility and durability, ideal for demanding mechanical applications and wear resistance. Some references also offer excellent fire-resistant properties.
Polyester Resin: Versatile and economical, perfect for lower-cost projects with reasonably good mechanical and even chemical resistance properties.
Polyurethane Casting Resin: Offers easy pouring and high strength, ideal for prototypes and custom parts.

Each described resin variant in this main category has a specific role in creating composite materials. Explore the subcategories we link to below to get a more detailed explanation of the properties of each resin type and their applications. We're here to provide you with the most suitable resin according to your budget and property requirements.
