- Lower density than competitive systems means lighter moulds
Neomould 2017-S-1 is a special formulation consisting of unsaturated Polyester resin based on DCPD and low profile additive dissolved in styrene. The resin is pre-accelerated and contains fillers. Neomould 2017-S-1 has moderate reactivity, medium viscosity and shows zero shrinkage upon cure.
Neomould 2017-S-1 is highly suitable for mold making as it shows low heat buildup in thin and thick layers as well as zero shrinkage during cure.
Neomould 2017-S-1 was developed for easy processing with good wet out of fiber reinforcement.
The color of the resin allows easy control of air pockets and bubbles during laminating.
The resin exhibits tack free cure without negative effect on secondary bonding. Enhanced thixotropic behaviour allows buildup of thicker laminate layers in one gowithout slip or drain from vertical surfaces.
Cured with 2.0 % MEK Peroxide. Cured 24h at room temperature, followed by post curing for 16 h at 60 ºC.
GUIDELINES BEFORE USE
Before work begins, the temperature of the workshop, the plug and the materials must be between 15 and 25ºC (ideally 21 ºC). Please keep in mind that materials taken from outside or from cold storage may require 2-5 days to reach workshop temperature. Homogenize pails and drums of tooling gelcoat and Neomould 2017-S-1 resin thoroughly prior to taking out any quantity.
Neomould 2017-S-1 can be applied by Hand lay-up and Spray-up processes. Best results are obtained when the different resin-fiber layers are applied evenly with similar thickness. Keep in mind to avoid excessive temperatures in the work shop, best results are obtained between 23 & 27 ºC.
Temperature development of Neomould 2017-S-1 measured in laminate on mold side (2 % Curox M 312):
The peak temperature of layers up to 10 mm in one go should stay below the critical Tg of the model surface. Thicker layers up to 12 mm did not show tendency for inappropriate peak temperature and did not negatively influence the zero shrinkage behaviour.
However, it is recommended to reduce the amount of the hardener when it is foreseen that thicker laminates will be build up in one go. Best results in thick layers over 8 mm and /or warmer work shop conditions are obtained with hardener content between 1.0 – 1.5 %.
The resin should be stored in a dark and dry place at temperatures between 5ºC and 30ºC. Shelf life is reduced at higher temperatures and the properties of the resin might change during storage.
The shelf life of styrene containing unsaturated polyesters will be significantly reduced when exposed to light. Store in dark and in 100% light tight containers only. Exposure to direct sunlight should be avoided.
From DCPD resins it is known that skin formation occurs when exposed to air ventilation or replacement from the original packaging.
