Proper use of release agent:
1, thin wall simple profile, the dosage can be appropriate less, such as 0.8% or less;
2, thick wall or shape of complex profiles need to add more;
3. In the high packing system, the addition amount of internal release agent should be increased, but the addition amount of internal release agent is too much, will delay curing;
4, in the pultrusion production, if the resistance is too large and can not find the reason, it is necessary to appropriately increase the release agent dosage; When using, attention should be paid to the feeding sequence. When mixing, the internal release agent should be added to the resin system and mixed evenly before adding curing agent, filler and other resin additives, so as to achieve the best release effect.
Release agent can play a separate function between the mold and the finished product, because the use of release agent has chemical resistance, and will not dissolve when in contact with different resins. Because the blister molding process is completed at high temperature, the release agent also has the effect of heat resistance, and has the function of not easy to decompose and wear.
