Product reference: 1/05
Product title: 200 Laminating Resin
Valid from: 14th August 1997
Last reviewed: 31 May 2019
Type: A two-pack cold cured Polyester Laminating Resin.
Suggested use
For use in wetting out with glass reinforcing tissues and fabrics.
Limitations
Not suitable for highly alkaline or polar solvents.
Health & safety
Before handling this product, the material Health & Safety Data Sheet for 200 Series should be consulted and all precautions observed. Only to be applied by competent, adequately trained personnel.
Surface preparation
Metal Surfaces: Grit blast to SSPC-SP10 (ISO 8501-1 Sa 2½) or equivalent. For full details refer to Corrocoat Data Sheet SP1.
Application equipment
As necessary for wetting out the reinforcing material. Can be used with brush, roller or spray.
Mix ratio
100:2 Base: Hardener.
Pot life
Variable with temperature.At 68°F (20°C) approximately 20-30 minutes.
Specific gravity
200 Laminating base 0.1 lbs/cubic inch (1.06 gms/cc)
Catalyst type
Methyl Ethyl Ketone Peroxide, Corrocoat Catalyst P2. In cold conditions, i.e. less than 50°F (10°C) Corrocoat Catalyst P4may be used if necessary to increase cure rate.
Overcoating
May take place as soon as the previous coat has gelled and while still tacky. Maximum overcoating time 72 hours.Please note: Maximum levels refer to ambient temperature of approximately 68°F (20°C). At higher temperatures themaximum overcoating time will reduce significantly.
Cure time
Full cure will be obtained in 4-6 days.
Cleaning solvent
Acetone, Methyl Ethyl Ketone and Methyl Iso Butyl Ketone prior to gelation.
Packaging
1 Gallon and 5 Gallon kits. Due to the hydroscopic nature of this product the use of part tins is not recommended.
Storage life
6 Months stored and away from heat sources and direct sunlight andbelow 68°F (20°C). Frequent temperaturecycling will shorten storage life and affect pot life.Beyond 6 months this product becomes increasingly susceptible to moisture uptake and foaming and out of shelf-life material must not be used. (All components must be used within their designated shelf life).
Color availability
Off white or unpigmented (translucent brown) only. Other colors are not available and it should be noted that the addition of dyes will adversely affect performance and in particular chemical resistance.
Thinners
The performance of 200 Laminating Resin may be adversely affected by the addition of solvent thinners (e.g. Xylene) and their use is prohibited. Should thinning be necessary use only styrene monomer to an absolute maximum of 5% by volume concentration.
Packaging
1 Gallon and 5 Gallon kits
Storage life
12 Months stored at temperatures below 75°F (24°C) and away from direct light and sources of heat.
Color
Translucent brown.
Flash point
88°F (31°C).
Recommended DFT
Not applicable.
Practical spreading rate
Dependent on roving usage.
Curing Time
Full cure is 4 days at 68°F (20°C). For optimum results a post cure of 4 hours minimum at circa 176°F (80 ̊C) is recommended. However, post cure is not necessary formany environments.
Spark testing
This product is subject to dielectric fatigue and repeated testing should be avoided, refer to data sheet 7/30
Cleaning fluid
Methyl Ethyl Ketone, Methyl Iso Butyl Ketone – before gelation.
Note
(1)Glassmat Reinforcement test work performed using 30% w/w of matting.
(2)All results tested at 68°F (20°C). Results will vary depending upon temperature, degree of cure, percentage of glass and quality of workmanship.
