Acetone stands as the preferred cleaning solution for removing uncured resin, topcoat, and Gelcoat from tools and ancillaries. Additionally, it is utilized for cleaning and degreasing substrates before or during fiberglass application.

RST-5 Concentrate is a specialized liquid solution designed for use with polyester resins in the composite industry. Typically, it is diluted with water at a ratio of 1 part concentrate to 20 parts water before application. This diluted solution serves various purposes such as cleaning, surface preparation, or enhancing certain properties of the polyester resin. It may aid in improving adhesion, reducing surface tension, or promoting better flow characteristics during application.

Silicone Rubber is a versatile material used in various composite applications due to its exceptional properties such as flexibility, durability, and resistance to extreme temperatures and harsh environments. It is commonly utilized as a mold-making material for composite parts due to its ability to capture intricate details and produce high-quality molds with excellent dimensional stability. Additionally, silicone rubber can act as a release agent, facilitating easy demolding of composite parts from molds. Its compatibility with a wide range of composite resins makes it a preferred choice for composite manufacturing processes such as vacuum infusion, resin transfer molding (RTM), and silicone rubber tooling.

Composite rubbing and polishing compounds are specially formulated abrasive materials designed to smooth, refine, and enhance the surface finish of composite materials through a process of controlled abrasion and polishing. These compounds effectively remove imperfections, scratches, and surface irregularities, leaving behind a smooth and glossy finish, thereby improving the aesthetic appeal and durability of composite products.

Some common types include:

There are several types of pigments commonly used in composite manufacturing:

Metal oxide cobalt (CoO) is added to composite materials to accelerate the curing process particularly those based on unsaturated polyester resins. It promotes the decomposition of peroxide initiators like MEKP, which speeds up polymerization. However, cobalt compounds should be handled with care due to their toxicity. Cobalt Oxide comes in various concentrations ranging from 1% – 11% for unsaturated polyester resins.

Here are some common types of fillers used in composite manufacturing:
