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.
