Do you know the core technology of fiberglass - sizing agent?

The role of wetting agents

1. Lubrication - protective effect

2. Bonding-bundling effect

3. Prevent the accumulation of static electricity on the surface of fiberglass

4. Provide good bonding with matrix resin
Classification of wetting agents

A. Textile sizing agent

It has good weaving performance and smooth yarn without hairiness. It is divided into starch type and paraffin type. It needs to be post-processed before use. Currently, it is rarely used except for spun yarns.

B. Enhanced infiltration agent

The sizing agent contains coupling agents, film-forming agents, lubricants and other components, which can be directly combined with the resin.

C. Textile enhanced sizing agent

The textile type is combined with the reinforced type, and the product can be used for weaving or direct use.
Components of the sizing agent

A. Coupling agent

Form a bridge between inorganic components and matrix resin

B. Lubricant

Meet the process smoothness of fiberglass production and subsequent use

C. Film-forming agent

Plays a bonding and bundling role for fiberglass

D. Auxiliary
