3. This product can harden hydroxide radical polyester ( generally, the acid value is between 20-50mgKOH/g; when the acid value is at 35KOH/g, it is in best condition.) When the temperature is 200¡æ, the harden time is 5 minutes; if the temperature is 150 ¡æ, time needed is 25 mintues; The best condition we commend is 180¡æ, and baking time is 15 minutes. This product is very sensitivity to benzoin, the surface can change yellow easily. To avoid this phenomenon, we should choose appropriate polyester resin and reduceBenzoin¡¯s doage.
