Common problems/solutions for composite material release agent products (adding release agent/extrusion)

compound materialtake offMold agentProduct common problems/solutions (adding release agent/extrusion)

Add release agent (pultrusion) inside
Product Features:Used for unsaturated resins and epoxy resins

Production process:Pull squeeze

Common problem (1):The surface powder produced by the product precipitates.
Solution (1):Suggest adding release agent to the liquid.

Common problem (2):The finished product is glued to the mold.
Solution (2):It is recommended to increase the proportion of mold release agent added, but adding too much can also delay curing.

The advantages of adding mold release agent in the extrusion process:

1. Easy to disperse in resin; 

2. Has the function of cleaning molds; 

3. Can protect metal molds from corrosion; 

4. Improve production efficiency while reducing extrusion resistance and mold loss;

5. It can reduce the surface tension of resin mixtures, lower resin viscosity, improve the resin's wettability with reinforcing materials and fillers, and enhance the resin's flowability; 

6. Assist in defoaming and improve the surface quality of components to make the product surface smooth; 

7. Does not affect the curing characteristics of the resin, does not change the shelf life of the mixed resin, does not affect the physical and mechanical properties of the product, does not affect the weather resistance of the product, etc
