Description
A high build, solvent-less two pot epoxy for the treatment of osmosis. It's supplied in two colours, blue and green, so that you can see where you've been and don't miss any parts. Each coat lays on a minimum of 150 microns.
This product has none of the harmful solvents of some products which may cause gelcoat blister to reoccur.
The mix ratio is 2:1 by volume, as supplied.
How to use it:
OSMOSIS TREATMENT: Gelcoat should be removed by blasting, or by peeling plus a light blasting. The resultant substrate should be carefully examined and professionally evaluated as chemically dry. Surface must be clean and dry prior to application of Epiglass HT9000 or Gelshield Plus. Contact International for further details.
Method OSMOSIS TREATMENT: Apply initial coat with a thin foam roller and work into the surface using a brush. (Alternatively,Epiglass can be used as the first coat in the scheme). Lay off with a brush making sure a minimum of 150 microns wet film thickness is applied (Minimum 150 micron wet film thickness is not essential when Epiglass is used as the first coat in the scheme). Fill as required using, Interfill 830, Interfill 833 or Watertite.
At temperatures of 10 to 15 degrees C it is recommended that the fast cure versions of Interfill 830 and Interfill 833 are used. If filler set to an extent that the surface does not move under light pressure, then overcoating can proceed. Otherwise, the filler should be sanded prior to application of Gelshield Plus. Apply a further 3 coats of Gelshield Plus by roller, each coat at least 150 microns. At shorter overcoating intervals, a wet on tacky application technique can be employed. As soon as Gelshield Plus is firm enough it can be overcoated with itself, even if the surface is still tacky.Hints Mixing
Stir contents of each part prior to mixing. Mix the base and curing agents of Gelshield Plus together at the specified mix ratio. Stir well before use. Pour immediately into a wide flat tray to prevent premature curing.
Thinning: Do not thin under any circumstances. Cleaner Epoxy Thinners No. 7 for equipment cleaning only. Ensure equipment is cleaned before product has gelled.
Other If self on self overcoating times are exceeded, abrade surface thoroughly to remove gloss. In some instances, depending on curing conditions, substrate temperature etc., the next coat may be applied faster than this. If the final coat over coating times are exceeded, abrade with 80 grade paper before application of Gelshield 200. If cold, and before mixing, store Gelshield Plus at room temperature for 12 hours or stand in containers of warm water to warm product up to approximately 15degC. Excessive warming will severely reduce pot life.
When applying by roller, laying off with a brush will aid release of any surface air. If the laminate requires re building Epiglass resin should be used. Do not use Gelshield Plus for any laminating work. Before antifouling can be applied a tie coat of Gelshield 200 is needed.
Some Important Points
Gelshield Plus is not suitable for application direct to gelcoat.
Do not use at temperatures below 10degC.
If a 'wet on tacky' technique is not used, and an overnight cure is allowed between coats, care should be taken that a very thin surface film or 'amine sweat' has not formed. In the event that this does happen, it can be removed by washing with warm water with a little detergent added. Then rinse with fresh water and allow the surface to dry before proceeding with the next coat.
Product temperature should be minimum 15degC/59degF and maximum 35degC/95degF. Ambient temperature should be minimum 10degC/50degF and maximum 35degC/95degF. Substrate temperature should be 3degC/5degF above dew point and maximum35degC/95degF.
Compatibility/Substrates Cured polyester laminates & epoxy fillers.
Gelshield Plus is not suitable for application direct to gelcoat.
