Applications
Mix the resins , fillers and other materials well to form a resin paste ,apply the paste on a first film , disperse chopped glass fibers evenly or the resin paste film and cover this paste film with another layer of resipaste film , and then compact the two paste films with pressure rollers of a SMC machine unit to form sheet molding compound products.

Storage
The fiberglass products should be stored away from heat and moisture, and in their original packaging. The best conditions are: temperatures between -10 ºC and 35 ºC; humidity between 35 and 65 %. If the product is not stored under these specifications, it is advisable to condition it in the workshop for at least 24 hours before use, to prevent condensation.
To ensure safety and avoid damage to the product, the pallets should be stacked not more than three layers high. When the pallets are stacked in two or three layers, special care should be taken to correctly and smoothly move the upper pallet.
