High chemical resistant, clear resin system.
abe.®cote sf 217 is a two-component, solvent-free novolac modified epoxy.
abe.®cote sf 217 clear resin system is used for sealing, laminating, screening and grouting applications. Not suitable for use on galvanised or other zinc coated surfaces.
Advantages
- High chemical resistance not possible with standard epoxies.
- May be used as a laminating resin.
- For high chemical resistance screening.
- For chemical tile grouting.
- For sealing porous elements such as concrete and wood.
Colour
Light amber – do not use pigments.
Surface Preparation
All surfaces must be clean, sound and dry. Moisture content tests must be conducted prior to application of the priming system. Maximum moisture content should be between 4-5%. (e.g. Protimeter Survey Master or equivalent) or Dynamic Calcium Chloride moisture “weight gain” over 24 hours or (a practical overnight “plastic sheet test” is also advisable approx. 1 m2masked down on surface)
Bonding / Priming
abe.®cote 384 for metal surfaces.

| Spread rate | A practical spread rate would be approximately 6 m2/litre/coat |
| Recommended number of coats | 2 minimum and 3 for adverse conditions. |
| Film build | Where film build is required a non-woven chemical resistant mat or tissue is generally used (e.g. a 25 gsm mass results in resin uptake of approximately 250 ml/m²) |
| Filled system | |
| Typical film thickness | 6 – 10 mm |
| Spread rate film thickness | 1 l/m² yields 1 mm |
Chemical Properties of Dry Film
See last 3 pages of this data sheet.
Properties of Cured Material
| Maximum service temperature | Chemical resistance best at ambient and dramatically reduced at higher temperatures (see charts on next pages) |
| Shrinkage during cure | Negligible |
Mixing
Add the entire contents of the activator tin to the base and, without splashing, stir with a flat paddle until homogeneous. This takes at least five minutes. Beware high summer temperature and overfast drill mixing causing extremely fast curing. Very low winter temperature retards/stops curing.
Coverage

Application
For laminating and sealing applications:
Apply abe.®cote SF 217 by brush or short -fiber roller. Overcoating times must be strictly adhered to. Final cure time, particularly in immersion situations, must also be adhered to. abe.®cote SF 217 must not be applied if the ambient temperature is below 5 ºC. The curing reaction will not proceed at low temperatures.
For screeding and grouting applications:
Premix the aggregate to obtain even distribution of the various fractions. When using a mechanical mixer, place mixed liquid in the pan and slowly add the premixed aggregate, mixing until an evenly coated wetted mix results. Use this procedure also if manual mixing is carried out in a drum. All lumps must be broken down and an even, wetted mass obtained. Apply by means of a pointing trowel to tiles, remove excess and ensure that surface is tooled to compact. When screeding, lay using plastic trowels and screed rails of the appropriate thickness. Rails should be kept as clean as possible otherwise false thicknesses will result.
abe.®cote SF 217 mortar mix:
The usual thickness of this mortar is 6 to 10 mm and it must be laid on to a surface which has previously been primed with a coat of abe.®cote SF 217. The applied screed must receive 2 coats of mixed resin to seal the surface.
Do not feather edge the product.
Approximate mortar yield:
5 L Resin kit + 3 x 9.5 kg aggregate *2 yields approx.17.0 Litres
Small areas should be laid at a time trowelled to a smooth surface and not touched again. Always maintain a wet edge joint where one area abuts another. Prime the edge using abe.®cote SF before edge before laying adjacent material.
Cleaning
abe® super brush cleaner before dried/cured.
Protection on Completion
Protect against traffic and spillage until cured. Most epoxies chalk and degrade in extensive sunlight.
Model Specification

Handling & Storage
All abe.®cote SF 217 related products have a shelf life of 12 months if kept in a dry, cool store in the original, unopened packs. If stored at high temperatures and/or high humidity conditions, the shelf life may be reduced.
Health & Safety
Wet abe.®cote SF 217 is toxic. Ensure the working area is well ventilated during application and curing Avoid inhalation of dust and contact with skin and eyes. Suitable protective clothing, gloves, eye protection and respiratory protective equipment should be worn. The use of barrier creams provides additional skin protection. If contact with skin occurs, wash with water and soap. Splashes into eyes should be washed immediately with plenty of clean water and medical advice sought.
Cured abe.®cote SF 217 is inert and nontoxic but must not be allowed to come into contact with foodstuff or drinking water.
NB: When transporting liquids and semi-liquids by aircraft, ask for material safety data sheet.
