A brief analysis of common problems in FRP mold gel coat resin

Feb 26, 2019

As a common category in unsaturated resins, FRP mold gel coat resins are special resins for making gel coat layers of FRP products, but this does not rule out some common problems during use. In the following content, we have selected common problems for everyone and analyzed the reasons. We also hope that you will not be anxious when encountering the problem of FRP mold gel resin. It is most important to find out the cause of the problem and then solve it.

Problem one, cracks and cracks

If a crack occurs, it is usually because the gel coat is too thick and the exothermic temperature is high. Moreover, the above problems may occur due to the excessive demolding and the impact of the external force on the surface of the gel coat.

Question 2, the gel coat wrinkles

Gel coat wrinkling is also a common problem with gel coat resins. This is mainly due to the fact that the gel coat is too thin, the thickness is not uniform, and the gel coat is not sufficiently cured. In addition, the high water content of the curing agent and the uneven mixing of the curing agent and the gel coat may cause the above problems.

Question three, the product gel coat is not shiny

Due to the low ambient temperature, high ambient humidity, coupled with the poor finish of the mold, dust on the surface, etc., it will cause the gloss of the product gel coat is not good.

Usually, when there is a problem with the FRP mold gel coat resin, you can first look at the problem of which part, and then find out the key reasons and solve it.
