Is vinyl ester compatible with polyester resin?
Ortho polyester, isothalic polyester and vinylester resins are compatible, they all have styrene (commonly known as the “fiberglass smell”) and chemically bond to one another.
What is the difference between epoxy resin and vinyl ester resin?
Vinylesters are more expensive than Polyesters. CRD Epoxy resins are much more suited to extremely strenuous tasks such as enduring vibrational loads, are more water resistant and environmentally stable than either Vinylester or Polyester resins, whilst providing higher tensile strength and thermal stability.
Should I use epoxy or polyester resin?
If the repair is critical or structural, an epoxy resin should be considered. If you are repairing an epoxy product, then epoxy should be used for the repair (polyester will perform poorly in this case). If you are repairing a polyester product, or non-critical part you should use a polyester resin.
How strong is vinyl ester?
VE vinyl ester resin
| PARAMETER | UNIT | VALUE |
|---|---|---|
| Tensile strength | MPa | 16-95 |
| Tensile modulus | MPa | 3,000-3,800 |
| Tensile stress at yield | MPa | 77-88 |
| Elongation | % | 2.5-9 |
How much catalyst do I need for vinyl ester resin?
about 1.5% catalyst
These resins only require about 1.5% catalyst and are quite specific on the ratios, especially in hot weather. You will also use the same ratio’s for Polyester-based putty, like our OEM Super Poly Fill, or our gelcoat putty.
What is the difference between epoxy and polyester resin?
Fiberglass mat should not be used with epoxy because the binding material in the mat will NOT dissolve in epoxy resin.
Will epoxy stick to vinyl?
The short answer is yes and no. First and foremost you will need to consider that the epoxy is only as durable as the surface it is bonded with. You will be applying the epoxy to the tiles rather than the concrete floor. Also, can you coat vinyl flooring? Many new vinyl tiles are designed to look like natural stone, with almost no sheen.
Which resin to use?

What is the difference between polyester and vinyl sticker?
Polyester (Mylar) – another option you have when it comes to tough label materials is Mylar, or polyester. This is considered a stronger material than vinyl since it is more tear resistant and can withstand exposure to oils, solvents, and a number of chemicals.
