The seam an agent of epoxy resin curing agent ( How much do you know? ）

The current joint seam epoxy beauty products, mainly used in market is composed of epoxy resin, curing agent, pigment and so on, the performance principle is from the produce curing reaction of epoxy resin and curing agent, so as to achieve the effect of solidification, the seam. Epoxy resin has the difference between domestic and imported, quality and price disparity is very big, curing agent also have different quality and price at the same time. Today is mainly tell everyone about a beautiful seam an agent of epoxy resin curing agent quality how to distinguish? The joint products on the market price from a few yuan to several hundred yuan, what's the difference between these products? How to identify the advantages and disadvantages? “ A price points a points goods & throughout; Is some truth in this sentence the

the curing agent of epoxy resin, roughly divided into two categories:

1, the reaction type curing agent

this kind of curing agent for aldehyde and aromatic organic compounds, such as formaldehyde and phenol, bigger toxicity.

2, catalytic curing agent

only the curing reaction, the catalysis of this kind of material is mainly caused by resin molecules in the ring opening polymerization of epoxy base, thereby the couplet body structure of polymer, itself is not involved in the crosslinked network, which does not produce toxic substances.

so consumer is when the choose and buy the seam an agent must choose type catalytic curing agent of the seam an agent products, because it does not contain toxic substances. Beautiful seam an agent factory beautiful seam an agent has been sticking to the principle of product quality, led, all products adopt type catalytic curing agent, to ensure the product of the rights and interests of consumers and health.
