Norpol® SVG Gelcoats
The New Low-VOC Gelcoat Series
Combining Performance and Processing
Robustness

[[ NORPOL® SVG Gelcoat
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 you 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.

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
Good fi lm fl exibility ensures
resistance to micro-cracking
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
