Product Introduction

◆ Special Properties

Trimethylolethane (TME) is a tri-functional neo-pentyl structure polyol. Due to the properties associated with its neo-pentyl structure and functionality,TME can provide the excellent stability and improve the property of heat, light, hydrolysis and oxidation resistance in n a variety of applications. Also, it possesses the distinguished weather ability, glossiness and chemical resistance.

◆ Application

TME is widely used as a raw material for the synthesis of alkyd and polyester resins with very good resistance to heat, moisture and UV light.TME is commonly used to prepare silicone modified polyesters and alkyds for high temperature applications such as pot/pan,bakeware, grill and muffler coatings.Resins prepared with trimethylolethane are noted for their superior weatherability and excellent colour, heat and alkali resistance.

TME is also widely used in organic surface treatment of titanium dioxide and other inorganic pigments,which mainly enhance products resistance to yellowing,resistance to high temperature,dispersion and gloss.It has strong commonality and be suitable for various types of titanium dioxide.

TME esters can be used as the lubricant base stocks.TME is the idea choice for polyol ester synthetic lubricants, plasticizers, stabilizers for plastics.TME may also be used as a solid phase heat storage medium.

Apply Advantage
