1 Epoxy Bodig Polyester Gelcoats Desiged to Bod to Epoxy Resi Systems

2 Excellece You Ca Trust Scott Bader has bee maufacturig polyester resis ad gelcoats for over 60 years uder the trademark. Scott Bader pioeered the use of FRP i may applicatios ad are very proud to have supplied the resi which maufactured the first ever composite boat the Tod 12 Dighy. Iovatio is at the heart of Scott Bader. The sigificat Research ad Developmet resources costatly strive to develop groud-breakig products for the composites idustry. This is supported by practical customer assistace from the Scott Bader Techical Service Team who have gaied a eviable reputatio throughout the idustry. The uique rage of polyester gelcoats desiged to bod to epoxy substrates demostrates Scott Bader's ability to offer iovative solutios. Epoxy Bodig Gelcoats A uique rage of polyester gelcoats with exceptioal adhesio to epoxy substrates allowig them to be used istead of a epoxy gelcoat. These gelcoats have bee used successfully by moulders who fid the product rage offers excellet performace i demadig epoxy applicatios whilst retaiig the ease of use of polyesters. This meas customers ejoy huge savigs o de-mould time ad repairs over epoxy gelcoats, i additio to payig a lower uit price.

Why Choose Epoxy Bodig Polyester Gelcoats Istead of Epoxy Gelcoat? Ease of Use ad Time/Cost Savigs Uique Product Beefits No back surface preparatio ecessary to achieve exceptioal adhesio.

3 Why Choose Epoxy Bodig Polyester Gelcoats Istead of Epoxy Gelcoat? Ease of Use ad Time/Cost Savigs Uique Product Beefits No back surface preparatio ecessary to achieve exceptioal adhesio. No tiecoat required. Polyester gelcoats ca be backed-up rapidly meaig de-mould times are sigificatly shorter resultig i huge productivity gais. Polyester gelcoat repairs are quicker ad easier savig cosiderable time ad moey. Exceptioally easy hadlig - simply add 2% MEKP catalyst ad spray or brush apply. Sag resistat - at recommeded thickess of 0.4mm - 0.8mm Sigificatly better UV resistace - atural Florida 12-moth weatherig testig has show excellet gloss retetio ad low colour chage. Cures at ambiet temperature - heated moulds ot required, although cure at o C will reduce back up delay. Supplied i ay RAL or colour-matched colour. Optimum overcoatig (back-up time) is 2 hours - maximum is 24 hours. Compatible with both epoxy lamiatig ad ifusio systems. High Tg demostrates ability to withstad higher operatig temperatures. Adhesio Testig Rigorous testig for adhesio to a umber of differet epoxy backig systems has bee carried out. The results match a complete epoxy system. Similar results are see across the Epoxy Bodig Gelcoat rage. Result of GC adhesio test showig that failure is iteral withi the lamiate Gelcoat Back Up Z-directio Delay Time Stregth (MPa) GC GC 2 hours hours 19.4 Epoxy 6 hours 18.9 Lamiate Failure Note 1: Values for GC used as a example. Other gelcoats i this rage show similar properties. Note 2: Results based o lamiates produced with liquid epoxy backig system cured for 16 hours at 50 C. Z-Directio Testig The Z-Directio test completed o GC showed lamiate failure, see image above. This proves that GC bods effectively to epoxy substrates as the gelcoat adhesio to the epoxy lamiate did ot fail. Same lamiate failure mode is achieved across the Epoxy Bodig Gelcoat rage.
