International & Awlgrip Yacht Paint Seminar Thailand 2016
สัมมนาเรื่องสี International และ Awlgrip ประเทศไทย ประจำปี 2559

East Marine Co Ltd Thailand and International Yacht Paints Singapore cordially invites you to attend Thailand's first International and Awlgrip Yacht paint seminar 2016.

We all know the importance of quality and the challenges a yacht painter has.

Knowledge of the correct quality products to use in building, repair and maintenance is sometimes misleading.

Guest speaker Mr Alan Koh, International Yacht Paints Singapore, will introduce new antifouling ranges available and specifically formulated for Yachts in the Asia Pacific region.

Topcoat vs Gelcoat 0

Topcoat

Famous paint manufacturers like Awlgrip, manufactures two different type of resin bases for urethane topcoats.  Awlgrip, which is a polyester urethane, and Awlcraft 2000 is an acrylic urethane.  Polyester molecules are much smaller than acrylic molecules.

A given volume of polyester resin contains many more molecules than the same volume of acrylic resin.  Thus, the polyester has more reaction sights than the acrylic.  This means that Awlgrip topcoat is the choice where harness is important (for example, resiting fender wear, deck areas, and etc) and maximum resistance to chemicals is necessary.  When both are fully cross-linked, polyester form a tighter, tougher film.  A denser cross-linking provides a harder, more abrasion resistant film with better chemical resistance.

Having a different cross-link structure than Awlgrip topcoat, Awlcraft 2000 cures faster which helps application in certain harsh environments.  The faster cure rate makes it the preferred choice if metallic finish is required.

High cross-link density also yields a rigid film.  In today's marketplace there is a need for both polyester and acrylic urethane technology.  Both will resist staining and provide long-lasting gloss.

Application characteristics, chemical and stain resistance, repair-ability and cure times all need to be considered when choosing a urethane products.

Benefits of Topcoat (Awlgrip & Awlcraft 2000)

•  Excellent chemical and abrasion resistance;
• Provides a durable finish with excellent gloss hold out and DOI (distinction of image);
• Awlgrip can be applied by spray or brush / roll;
• Outstanding colour retention;
• Great resistance to UV degradation (for example: yellowing) and salt erosion;
• Custom colour available through Awlmix system;
• Superior flow-out;
• Provides a smooth and dense film for easy maintenance;
• Will prolong the aesthetic appearance of a fibreglass boat;
• Compatible with a range of Awlgrip primer systems.

 Limitations of Topcoat 

• Use above the waterline only (not for continuously immersed substrates);
• Topcoats recommended for professional application only;
• Repairs is usually carried out by professional applicators only;
• The extreme gloss can highlight any imperfections in the surface underneath.

Gelcoat

Gelcoat is made of a polyester resin although different to a paint in its chemical composition.  It's a thick material used during fibreglass boat construction to achieve a durable, cosmetic finish.

The gelcoat is applied as a thick coating in the mold.  Once lamination is complete, the hull is removed from the mold.

In order to remove the mold, release agents are used on the mold surface prior to application of the gelcoat.  Mold release agents vary but often consist of wax.  A product like gelcoat builds thick layer and with a high pigment load, the coating is slightly porous.

This porosity will become worse over time as the resin layer wears away and exposing the remaining material to UV degradation, resulting in a chalk-like finish as oxidisation occurs, and discolouring.

Coloured gelcoats are prone to degrade faster than white gelcoats due to the natural light reflectance in white pigments like titanium dioxide.

Benefits of Gelcoat

• Less gloss (minor scratches don't show as easily);
• The softer polyester resin allows for easy buffing and polishing;
• Offers a smooth surface for paint;
• Gelcoat repair kits are widely available, at a reasonable price.

Limitation of Gelcoat

• High maintenance (requires polishing with abrasive materials and waxing to prolong a glossy surface), this will be more at tropical countries due to higher temperature;
• Years of high maintenance reduce the thickness of the resinous layer at the surface, increasing the amount of maintenance needed to maintain gloss;
• Colour choice limited (including colour choice of repair kits);
• Gelcoat repairs can be labour intensive as the surface must be sanded and polished again;
• Porous surface is difficult to clean, especially around exhaust pipes, waterline and non-skid decks without using chemicals.  This includes water spots;
• Softer resin system means more fragile, so may spider and chip more easily.
