Still using inferior curing agent?

Curing agent, also known as methyl ethyl ketone peroxide, is the most commonly used additive in fiberglass technology. Almost all fiberglass manufacturers' necessities, the amount of which is usually 1% -2% of the amount of resin, although the proportion is small, but it plays a crucial role in the quality of glass steel products.

 

According to statistics, there are currently more than 50% of resin curing quality problems caused by poor quality curing agents. No wonder many questions are heard: "I use the top grade resin. Why is the product still having problems? Isn't the quality of the resin? "The poor number of resin suppliers has become a pot.

The truth is often: the fault of inferior curing agent

 

Although curing agent is a small part of the production process of glass steel products, it has played a crucial role in the quality of the entire product, so even if you buy a high-grade resin, it is matched with a qualified level. Curing agent will eventually get a "deteriorated" product.

 

Two indicators of the quality of the hardener

1. Moisture content: Whether or not the dehydration process is carried out has become a key factor in distinguishing between the quality safety and the dangers of inferior quality. The international standard for methyl ethyl ketone peroxide is generally less than 5%, while domestically produced is generally more than 20%. Although the curing agent with high water content is cheap, but due to the presence of a large amount of water will cause the resin to cure abnormalities, (resin cured most afraid of water ). Severely affects the strength of FRP products, and will produce water mist and air bubbles.

 

2. Flash point: This is a very important safety indicator. The high-quality curing agent has a flash point of more than 70 degrees and can be used safely under any conditions. The poor quality curing agent is often only more than 30 degrees, in the summer high temperature is prone to safety accidents.
