Applications
Adhesive-free final coat (topcoat) for a polyester laminate as protective layer and finish.Can be coloured with a maximum addition of approx. 5-10% UP pigment. Spraying is possible with the addition of approx. 5% styrene. Has its application in amongst others swimming pools, containers and tanks as well as elements for the construction industry. Topcoat LT 40 SB is always processed in combination with precoat T 40 BT for a good chemical and water resistance with a maximum water temperature of 30°C. Recent tests have shown that the use of salt solutions at elevated temperatures can cause black spots in the final coat. The use of this topcoat LT40SB is therefore not recommended.Tip: some colour pigments discolour faster than others! For example: dark grey will fade.
Usage
Mix LT40SB with 2-3% Mekp hardener and possibly 1% extra cobalt accelerator when mixing with colour pigments, as these can slow down the process. Never mix cobalt directly with Mekp hardener, but separately in the resin. Brush or roll a fairly thick layer on the surface to obtain complete hardening. Avoid too much sun or too high temperatures, otherwise the topcoat will remain sticky.Potlife: approx. 15-20 min. at 20°C. Always apply small quantities in proportion to the potlife. Processing temperature: 18-25°C.Tip 1: must cure for 7 days at 20°C, then fill with water.Tip 2: all polyesters can be slowed down with inhibitor.Tip 3: use a different colour between the T40BT( precoat) and LT40SB (topcoat). This gives a better visual control.Tip 4: when T40BT (precoat) comes into contact with water, it turns white). The quantities in grams below are the same as in ml. Polyester resinSafety
