So, laminating resin is just for forming a mold around the glass. Sanding resin is for applying a thin sandable coat on top of the laminating layer.
What is the difference between laminating and finishing resin?
Polyester resin comes in two forms, a laminating resin that does not contain wax, and a finishing resin that contains wax. Polyester laminating resin remains tacky to the touch and does not cure in the presence of air, making it ideal for layups. Polyester finishing resin contains wax, which allows the resin to cure.
What is the role of resin in laminate flooring?
While the reinforcement fibers provide the primary strength for a laminate, the role of the resin, transferring that load to across an array of fibers, is also paramount to the overall strength and stability of a part.
What is the difference between gelcoat and laminating resin?
Laminating Resin and Gelcoat are both polyester resins, use MEKP catalyst, contain styrene, and can be tinted with compatible colorants. However, Gelcoat typically contains ISO (isophthalic) resins that give it stronger UV and water resistance for use as a finish coat.
Can laminating resin cure on its own?
Yes, it will cure on its own. Finishing resin contains wax, which enables the resin to cure. Laminating resin does not contain wax, so it will not cure. When you are done building up layers, you will need to apply a coat of finishing resin. One good complete coat is all you need to cure the previous laminating layers.

What is polyester molding resin?
Polyester Molding Resin is a general purpose polyester resin, ideal as a orthophthalic fiberglass resin for part fabrication and for building low cost molds. This resin is easy to work with, less expensive compared to it's epoxy and vinyl ester counterparts, and is wax free, meaning you won't have to sand between coats.
What is fiberglass resin?
The majority of all fiberglass parts are constructed using polyester resins, it's the most widely used type of resin in the composites industry. Polyester resins require a catalyst to cure or harden, typically methyl ethyl ketone peroxide ( MEKP ). They are naturally UV resistant, generally viewed as easy to use, fast curing, tolerant of temperature and catalyst variations, and they are less expensive than epoxy systems. Many view polyester resins as being easy to use because they have a high thixotropic index, basically they do a good job clinging to vertical surfaces so the resin won't run or drip as much when making parts and molds. They also wet-out fabrics quickly and easily and they are easy to mix. As the most common resin type in the industry, it can be difficult to narrow down a list of common uses. That said, you can expect to find polyester resins used in the marine industry, used for boat hulls and other applications, they are used for general part fabrication, automotive applications, and for low-cost molds.
How does resin help fabric?
First, resin holds the reinforcement fabric together while helping it conform to the desired shape. Without a hardened resin to provide shape, reinforcement fabrics are shapeless and can easily be separated. Second, resins help transfer mechanical loads from individual fibers or fiber bundles across the entire part.
Why is polyester resin so easy to use?
