1、Gelcoat wrinkled
Formation reasons：The gelcoat layer solidified insufficient to carry out the next step.
Solution：According to the ambient temperature, humidity, adjust the formula, curing fully after the construction.
2、Uneven colors
Formation reasons：Color paste has expired or stratified,the paste is mixed unevenly after being added.
Solution：Mix well before using the paste，stir well after adding the resin.
3、Sundries on the surface
Formation reasons：Contaminated by smoke, dust and insects.
Solution：Keep the operation place clean.
4、The surface of the product is sticky
Formation reasons：The resin does not contain enough wax.
Solution：Add wax to the resin.
Formation reasons：Mix with other water or other solvents.
Solution：Keep the operating place and tools clean, and no solvent should be added to the resin.
Formation reasons：The amount of cobalt water and curing agent is insufficient.
Solution：Increase propriately cobalt water, methyl ethyl ketone.
5、Flow glue serious
Formation reasons：The amount of cobalt water and curing agent is insufficient.
Solution：Increase propriately cobalt water, methyl ethyl ketone.
Formation reasons：Resin viscosity too low.
Solution：Added appropriate amount of thixotropic agent.
6、Product layered
Formation reasons：Bad glass clothor or wax.
Solution：Dewaxing treatment or replacement of glass cloth.
Formation reasons：Improper handling, too much or too little resin.
Solution：Use defoaming stick carefully to make resin content uniform.
7、Too much bubble
Formation reasons：Improper selection of glass cloth.
Solution：Use a suitable glass cloth.
Formation reasons：Resin viscosity too high.
Solution：Add styrene, adjust viscosity, use a stick to roll.
Formation reasons：Overdosage of resin.
Solution：Appropriate control of gum content.
8、White product
Formation reasons：Resin mixed with water or moisture.
Solution：Note resin storage conditions: drying glass cloth before producing.
Formation reasons：The operating environment humidity is too high.
Solution：Controls the temperature and humidity of the environment.
9、Burnt product
Formation reasons：Product is too thick.
Solution：The thickness of disposable molding products should be controlled below 10mm.
Formation reasons：Too much curing.
Solution：Reduce accelerant use.
10、Poor curing
Formation reasons：Too little curing agent, accelerator dosage.
Solution：Increase the dosage of accelerant and curing agent.
Formation reasons：Curing agent activity is poor.
Solution：Replace curing agent.
Formation reasons：The curing agent didn't mix well.
Solution：Mix the ingredients well.
Formation reasons：Glass cloth contains too much water.
Solution：Use the glass cloth after baking.
11、Uneven thickness
Formation reasons：The glass cloth is not properly laid.
Solution：Concentrate your thoughts and work carefully.
Formation reasons：Too much resin, glass cloth displaced.
Solution：Control the amount of glue.
12、Products warp
Formation reasons：The product area is too large.
Solution：Appropriate reinforcement.
Formation reasons：Demoulding before complete curing.
Solution：Demoulding after curing.
13、Product deformation
Formation reasons：Deformation of the molds.
Solution：Repair and correct molds.
Formation reasons：Improper placement after demoulding.
Solution：Support the product with brackets after demoulding.
14、Local contraction
Formation reasons：Too much local resin.
Solution：Do not let the corner, groove resin stagnant too much.
Formation reasons：Local thickness is too large.
Solution：The product is fully cured and then reinforced.
15、Demoulding difficulty
Formation reasons：Mold design.
Solution：Avoid right angles in mold design.
Formation reasons：Curing agent, promoting dose is insufficient.
Solution：Extend the demoulding time.
Formation reasons：No release agent or poor release agent is used.
Solution：Use a better release agent.
Formation reasons：Resin mold is not applicable: mold has hard mold, soft mold.Such as Model S30127 is not applicable to hard mold.
Solution：Choose a suitable mold.
