Stir the container slowly for 5 minutes before using. Do not over mix as this will cause loss of thixotropic properties. If the product is over mixed, let it rest for at least 4 hours to recover original properties. Apply the gel coat in several thin passes to avoid...
Viscosity:Viscosity is a fluid’s resistance to flow. The fluids that have less viscosity can flow easily (like water) while fluids with high viscosity can flow relatively more difficultly (like honey). The unit of viscosity is either “cp” or “mPa.s”. When...
Before starting to build the mold, make sure that the pattern has a perfect surface. Since the surface quality of the mold will replicate the pattern, the surface of the pattern should be worked carefully, and the surface coating material should be checked for...
One of the challenges of hand lay-up process is to obtain the right resin/glass ratio in each application. In order to control the ratio, below methods can be followed; 1. Visual Check: Visual check provides a good idea about the quality of lamination. – A laminate...
Polyester Resin :Polyester resins typically contain around 35-45% styrene monomer which has a flash point of 32 °C. Therefore all sources of flame, sparks and static electricity must be avoided at all times. Smoking is strictly prohibited in areas where resins are...
Within the simplest terms, polyester resins are unsaturated polymers formed by the reaction of poly functional acids and poly functional alcohols. They are classified as Saturated and Unsaturated Polyester Resins based on their chemical...
