What is Fiberglass Resin?Fiberglass Resin vs Epoxy Resin
Fiberglass Resin, also known as fiberglass resin, is a high-performance material widely used for boats, car construction and many other repairs. This high-performance polymer can be utilized with fiberglass mats, fiberglass cloths or fabrics on most surfaces like fiberglass, wood, metal or concrete to repair rust-outs or to reproduce or join different surfaces. Most fiberglass resin kits come with the fiberglass resin itself, but fiberglass resin kits can also be purchased separately. Either type of fiberglass resin kit can be mixed together using fiberglass resin mixers and then applied to any surface to create a smooth, durable or custom fit product.
Types of Fiberglass Resin
The three major types of fiberglass resin are acrylic, epoxy and fiberglass cement. Each type of fiberglass resin has its own advantages and drawbacks depending on application needs. Understanding fiberglass resin and fiberglass grout before purchasing a fiberglass resin kit will help ensure the correct application technique for the job.
Acrylic fiberglass resin is typically used in fiberglass boat decks and custom make door panels because it provides a clean, smooth surface to work on and provides excellent resistance to wear and tear. Many fiberglass manufacturers also produce fiberglass resin that can be added as a second coating to an existing fiberglass surface. This second coat can provide additional strength and durability.
Epoxy fiberglass resin is made from two chemicals – resin and binders. To produce the finished product, epoxy fiberglass resin is mixed with water and either applied with fiberglass resin mixers or with a paint brush. The process seals the fiberglass material to the desired surface. The resin and binders combine to create a smooth, glossy, durable finish. This resin is also used in flooring repair projects.
Fiberglass resin is less expensive than fiberglass resin kits, but it’s not as strong as industrial strength polyester resin. To give fiberglass resin an extra boost, it’s combined with hardeners like iron oxide. This creates a thicker, stronger layer of fiberglass resin that’s more appropriate for heavy duty outdoor applications such as fiberglass boat decking. The resin-like coating doesn’t have as much flexibility as other types of fiberglass resin, so it’s not recommended for cutting or shaping. It’s best suited for cosmetic repair projects such as sanding and honing.
If you’re planning a door panel restoration project, the fiberglass resin you’ll use won’t have to be very thick. In fact, fiberglass resin can’t be too thin because it will fail to cure properly and could crack. Many door panels are made from fiberglass resin and only need a very thin coating applied to them in order to work. The thickness of the first coat is up to the contractor and depends largely on the area being worked on and the amount of detail that needs to be removed.
Fiberglass Resin Kits
Most fiberglass resin kits contain fiberglass resin, a hardening agent and some filler. The hardening agent is often graphite. However, many companies also use white fiberglass resin for the construction of custom make door panels. Although fiberglass resin is popular, it isn’t suitable for all applications. It’s often used in residential door panels for its light weight, durability and noncorrosive properties. Although fiberglass resin can work outdoors, there are a number of considerations to keep in mind if you’re going to use it for residential repairs or custom make door panels.
The fiberglass resin should be sealed properly if you want it to work correctly and last for a long time. The resin should be cured for at least 24 hours prior to working. During this curing process, the fiberglass resin is exposed to an external atmosphere that helps it resist corrosion. This external environment can often be detrimental to fiberglass resin doors if it’s not done correctly. Proper ventilation is essential as well as an interior vacuum for fiberglass resin door panels.
