TOTALLY SOLVENT FREE OSMOSIS PREVENTION COATING FOR GRP
SAFEGUARD TSF is a totally solvent free, two part epoxy coating that contains a high content of minute ceramic micro-spheres which enhance the epoxies natural water resistant properties. It has been specifically developed for use on GRP hulls for protection against “osmosis”. The result is a coating which is incredibly abrasion resistant and which has extremely low permeability to oxygen and water vapour. It should be used where effective osmosis protection coating is required with the ability for multiple coats to be applied in quick succession without the fear of solvent entrapment.
- Totally solvent free
- Can be rapidly over-coated for quick completion of the job.
- Excellent inter-coat adhesion
- Excellent water barrier properties
On existing boats, all antifouling must be removed by using STRIPPIT or STRIPPIT OFF antifouling remover, scraping or blasting. The surface must then be degreased and abraded as above.
MIXING Epoxy resins and hardeners must be thoroughly mixed in the correct ratios to ensure complete curing of the product. Each can of SAFEGUARD TSF is supplied with the correct amount of hardener, all of which must be added to the can of resin and mixed well immediately before use. Do not try to accelerate or retard setting of the material by varying the amount of hardener used as this will cause the coating not to set at all, or to prematurely fail. Thorough mixing is also critical to the correct curing of the product and although small packs can easily be mixed by hand, a spiral mixer used in a pneumatic or cordless drill is essential for mixing larger packs. Once mixed SAFEGUARD TSF will remain usable for between 30 and 90 minutes, depending on the ambient temperature. Pot life can be extended by pouring the mixed material into trays which will allow the exothermic heat generated by the curing reaction of the resin and hardener to dissipate. If a small amount of material is required the components must me accurately weighed in the proportions shown on the hardener label. Because solvent must not be added to this material it should not be applied when the ambient temperature is less than 12ºC.

The ceramic micro-spheres are totally impervious to water. Their perfectly spherical shape enable a high packing density in the coating that help prevent water penetration.

SAFEGUARRD TSF is aeasy to apply by roller or brush.
APPLICATION SAFEGUARD TSF is usually applied with a 7” short pile simulated mohair roller. Wash the roller before use and allow to dry to prevent bits of loose fabric from spoiling the finished coating. A special grade is available for application by high-pressure airless spray.
SAFEGUARD TSF must be spread evenly to avoid runs or curtains. Load the roller and apply in one direction to an area approximately 800 mm square. Roll at 90° to the first direction until the SAFEGUARD TSF has been spread evenly. To obtain a smoother finish when applying the last coat, the stippled effect imparted by the roller can be removed by laying off with a good quality 4 or 6 inch brush.

SURFACE PREPARATION SAFEGUARD TSF should only be applied to GRP hulls, which are in good condition with low moisture content - (recommended at below 5%). If the hull has a high moisture content, please refer to our “OSMOSIS PREVENTION & REPAIR GUIDE” for details of the work required.
New GRP surfaces must be thoroughly degreased with solvent using plenty of clean cloth, and thoroughly abraded to a matt finish with a Nippy Disc or a dual action sanding machine to provide a mechanical key and improve adhesion. The sanded surface must then be wiped over with a clean cloth soaked in SYNSOL 100 solvent to leave the surface clean, dry and dust free.
