Melamine clear sealer/topcoat

Melamine wood coatings is 2K acid cure system which is basically used to have mid range performance properties along with price benefits as compared to polyurethane chemistry. Melamine system offers smooth dried surface finish with faster drying and early hardness achievement characteristics. Also their high surfaces covering property and ease of application makes it suitable and first choice as wood coating at mass scale wood furniture manufacturer.

Chemically it is called as melamine coating but the major amount of resin component is short oil alkyd resin and urea formaldehyde resin. Melamine formaldehyde resin is also used as an additive percentage just to increase water repellence and improve stickiness issue of melamine wood coating in cold climatic conditions. Also the cost of MF resins is much higher than any commercial alkyd and UF resin.

While formulating melamine wood coatings, the balance of Alkyd:UF ratio is very important in order to perform in terms of covering, drying, gloss level, hardness development and etc. Also the selection of acid for curing of coating and its addition level plays very important role. With less or more amount of hardener than what is actually required will have performance changes compared to the actual one. Performance properties like cracking and stickiness will arise. With excess of hardness and also because of high coating thickness, cracks can be seen after a month of application throughout the substrate and with less amount of hardener addition, stickiness issue will be major issue.

As the coating has aromatic backbone resin chemistry, it is strongly recommended to use only as interior wood finishes.

Melamine finishes can be applied on all types of wood substrate and is available in both clear and pigmented systems.

Generally RMC for 2K melamine clear sealer or topcoat will cost around Rs. 95-100/ltr and for pigmented system it would be around Rs. 140-145/ltr including all sorts of costing.
