Car body parts, spoilers, etc. composite products are being manufactured in sub-industry by using sanding type gelcoat and sent to the main manufacturers for final paint applications. Manufacturers after complained about creakings occurred on painted parts during the mounting process. As a result of R&D studies , İlkalem solved this problem by designin brush type G-318 and spray type G-18 gelcoats. These resins called “New Generation” have super dry sanding characteristics. These composite products, following the primer and finishing paint applications are dried in paint ovens. Then subjected to cross cut tests and perfect results achieved. As per the requirements of automotive sector, they are mostly colored in black, white and gray colors. Besides solving the cracking problems of the manufacturers also providing ease of production and increasing the product quality to the top level.
