Polyester Resin (Inspec 222-60 LSE Low Styrene) 22.5kg- Waxed

Pre-accelerated, thixotropic, low styrene emission unsatrurated polyester resin with fast wet out and fast cure rate.Designed for hand lay-up and spray applications for high performance marine products and meets LSE requirements. It also exhibits lower shrink characteristics and low colour in thicker laminates.

Features:

• Low styrene emission- Improves safety by reducing styrene levels in the work place
• Excellent interlaminar adhesion- Delays of up to 4 days between consecutive layers*
• Low Styrene Content- Low shrink, less print through
• Excellent wet out of glass fibres- Easy and fast to roll out glass reinforcement
• Thixotropic- Minimal drainage
• Non air-inhibited (contains wax)- Cures to a tack-free finish
• Blue colour change- Confirms catalyst addition

Typical Liquid Properties:

• Specific Gravity- 1,08 - 1,10
• Viscosity @ 25°C (cP)- 2500 - 6500
• Volatile content, %- 36 - 39
• Geltime @ 25°C, using 2% CUROX M200 MEKP,(minutes)- 27 – 33
• Liquid appearance- Opaque blue
• Stability in the dark @ 20°C, months unopened- 4 minimum

Curing Characteristics

INSPEC® 222-60 requires the addition of catalyst ONLY to start the curing reaction. The Curox M200 must be thoroughly dispersed in the resin. The resin should be allowed to attain workshop temperature (23°C) before being formulated for use.

The ambient temperature and the amount of catalyst and accelerator control the geltime of the resin formulation. This can be approximately determined from the table below which shows the geltime of 100 grams by mass of
INSPEC® 222-60 catalysed with 2 ml CUROX M200.

Inter-Laminar Adhesion

INSPEC®222-60 has been tested and found to have good inter-laminar adhesion. When a laminate is built up in stages with intervals that allow intermediate curing, each layer should be finished with the correct resin to glass ratio. Any surface having an excess of resin must be abraded and thoroughly cleaned before further laminating is commenced. During construction, using a normal resin/glass fibre ratio, it has been found that an interval of 4 days is acceptable between laminate layers, provided that suitable control of the environmental conditions as per *Lloyds Register are applied. Beyond this period, it is essential to abrade the laminate surface to form a mechanical key prior to continuing.

Post-Curing

Satisfactory laminates for many applications can be made from INSPEC® 222-60 by curing at ambient temperature (but not less than 15°C). When optimum properties and long-term performance are required however, the laminate should be post-cured.
After release from the mould, laminates should be allowed to mature for 24 hours at workshop temperature (23°C). They should then be post-cured for 3 hours at 80°C, although a longer period at a lower temperature will give almost the same result. The post-cure is most effective if it is carried out immediately after the 24 hour maturing period.
For all applications involving foodstuffs, it is essential to follow the recommendations detailed under 'Food Containers'.

Pigments & Fillers

The addition of fillers or thixotropic additives may reduce the chemical resistance of INSPEC® 222-60 and is not generally recommended.
The same consideration applies to pigments, but when absolutely necessary, INSPEC® 222-60 may be pigmented by the addition of up to 4% of Pigment Paste.

Storage & Handling

To ensure maximum stability and maintain optimum properties, polyester resin should be stored in closed containers, maintained below 25°C and away from heat sources and sunlight. All storage should conform to local fire and building codes.
