NORPOL SVG Gelcoats The New Low-VOC Gelcoat Series
Combining Performance and Processing Robustness
Are you looking for help to reduce VOC emissions in your manufacturing operation?
You are not alone. Changing European regulations are driving the need to have a closer look at the processes and materials that are being used. Also, many companies are trying to further improve working conditions.
Many of our customers have made the decision to introduce closed-mould processes, and have expressed the desire to work with low-VOC raw materials. As the application of gelcoat can be expected to remain an open mould process for the foreseeable future, a low-VOC gelcoat will be required.
Your solution: NORPOL SVG Gelcoats
• Allowing for a signifi cant reduction in emission of volatiles• Excellent protection from weathering: retention of gloss/ colour• Excellent mechanical properties• Improved surface aesthetics • Easy to apply: processing robustness enables high quality manufacturing under different external
temperatures• Applications include sanitary components, boats, car bodywork, cladding panels, etc.
Approved by Lloyds and Det Norske Veritas (DnV) for boat building.
Low-VOC and Processing Robustnesss
Low-VOC content and low VOC emission• Spray product (in white colour) contains 30%
volatiles, brush product 25%• Styrene evaporation reduced by half vs. traditional gelcoats• Monomer is styrene, no additional monomers/ solvents
Excellent application properties• Easy fl ow, air release, and curing• Application in broad temperature range
Improved weathering resistance over NORPOL NGA Gelcoats• Better colour retention compared to conventional ISO/ NPG gelcoat• While gloss retention is comparable
Based on premium ISO/ NPG resin systems• Well-suited for contact with water/ less aggressive chemicals
Good fi lm fl exibility ensures resistance to micro-cracking.
